Comentarios

Utilice esta sobrecarga del método para especificar atributos que no funcionan correctamente a menos que se aplican cuando se crea un ensamblado dinámico.Use this method overload to specify attributes that do not work correctly unless they are applied when a dynamic assembly is created. Por ejemplo, atributos, como seguridad SecurityTransparentAttribute y SecurityCriticalAttribute no funcionan correctamente si se agregan una vez creado un ensamblado dinámico.For example, security attributes such as SecurityTransparentAttribute and SecurityCriticalAttribute do not work correctly if they are added after a dynamic assembly has been created.

Las solicitudes de permisos especificadas para el requiredPermissions, optionalPermissions, y refusedPermissions parámetros se usan solo si el evidence también se proporciona el parámetro, o si el ensamblado dinámico se guarda y vuelve a cargar en memoria.The permission requests specified for the requiredPermissions, optionalPermissions, and refusedPermissions parameters are used only if the evidence parameter is also supplied, or if the dynamic assembly is saved and reloaded into memory.

Nota

Al desarrollar código que emite ensamblados dinámicos, se recomienda que incluya el SecurityPermissionFlag.SkipVerification marca en el refusedPermissions parámetro.When you develop code that emits dynamic assemblies, we recommend that you include the SecurityPermissionFlag.SkipVerification flag in the refusedPermissions parameter. La inclusión de esta marca garantiza que se comprobará el lenguaje intermedio (MSIL) de Microsoft.The inclusion of this flag ensures that the Microsoft intermediate language (MSIL) will be verified. Esta técnica detectará la generación de código no comprobable, que en caso contrario, es muy difícil detectar involuntaria.This technique will detect the unintentional generation of unverifiable code, which otherwise is very difficult to detect. Una limitación de esta técnica es que también hace que SecurityException se produce cuando se utiliza con código que requiere plena confianza.A limitation of this technique is that it also causes SecurityException to be thrown when it is used with code that demands full trust.

Solo los llamadores de plena confianza pueden suministrar la evidencia al definir un dinámico Assembly.Only fully trusted callers can supply evidence when defining a dynamic Assembly. El tiempo de ejecución asigna el Evidence a través de la directiva de seguridad para determinar los permisos concedidos.The runtime maps the Evidence through the security policy to determine the granted permissions. Deben proporcionar los llamadores de confianza parcial null para el evidence parámetro.Partially trusted callers must supply null for the evidence parameter. Si evidence es null, el tiempo de ejecución copia los conjuntos de permisos (es decir, la concesión actual y denegar conjuntos) desde el ensamblado del llamador en el ensamblado dinámico que se está definiendo y marca la directiva como resuelta.If evidence is null, the runtime copies the permission sets (that is, the current grant and deny sets) from the caller's assembly to the dynamic assembly that is being defined, and marks the policy as resolved.

Si el ensamblado dinámico se guarda en disco, posteriores cargas obtendrán las concesiones en función de las directivas que están asociadas con la ubicación donde guardó el ensamblado dinámico.If the dynamic assembly is saved to disk, subsequent loads will get grants based on policies that are associated with the location where the dynamic assembly was saved.

Si isSynchronized es true, los métodos siguientes de resultante AssemblyBuilder se sincronizarán: DefineDynamicModule, DefineResource, AddResourceFile, GetDynamicModule, SetEntryPoint, y Save.If isSynchronized is true, the following methods of the resulting AssemblyBuilder will be synchronized: DefineDynamicModule, DefineResource, AddResourceFile, GetDynamicModule, SetEntryPoint, and Save. Si dos de estos métodos se llaman en subprocesos diferentes, uno se bloqueará hasta que se complete la otra.If two of these methods are called on different threads, one will block until the other is completed.

Esta sobrecarga del método se introdujo en la .NET Framework 3,5.NET Framework 3.5.This method overload is introduced in the .NET Framework 3,5.NET Framework 3.5.

Comentarios

Las solicitudes de permisos especificadas para requiredPermissions, optionalPermissions, y refusedPermissions sólo se utilizan si evidence también se proporciona, o si el ensamblado dinámico se guarda y vuelve a cargar en memoria.The permission requests specified for requiredPermissions, optionalPermissions, and refusedPermissions are used only if evidence is also supplied, or if the dynamic assembly is saved and reloaded into memory.

Nota

Durante el desarrollo de código que emite ensamblados dinámicos, se recomienda que incluya SecurityPermissionFlag.SkipVerification en refusedPermissions.During the development of code that emits dynamic assemblies, it is recommended that you include SecurityPermissionFlag.SkipVerification in refusedPermissions. Incluyendo SkipVerification en el refusedPermissions parámetro garantiza que se debe comprobar el código MSIL.Including SkipVerification in the refusedPermissions parameter ensures that the MSIL is verified. Una limitación de esta técnica es que también hace que SecurityException se produce cuando se usa con el código que solicita plena confianza.A limitation of this technique is that it also causes SecurityException to be thrown when used with code that demands full trust.

Solo de plena confianza para los llamadores pueden suministrar sus evidence al definir un dinámico Assembly.Only fully trusted callers can supply their evidence when defining a dynamic Assembly. El tiempo de ejecución se asignará el Evidence a través de la directiva de seguridad para determinar los permisos concedidos.The runtime will map the Evidence through the security policy to determine the granted permissions. Los llamadores deben suministrar un valor null de confianza parcial evidence.Partially trusted callers must supply a null evidence. Si evidence es null, el tiempo de ejecución copia los conjuntos de permisos, es decir, actual otorgar y denegar los conjuntos, desde el llamador Assembly a dinámico Assembly que se está definiendo y marca la directiva como resuelta.If evidence is null, the runtime copies the permission sets, that is, the current grant and deny sets, from the caller's Assembly to the dynamic Assembly being defined and marks policy as resolved.

Si el dinámico Assembly está guardado en el disco, carga posteriores obtendrán las concesiones en función de las directivas asociadas a la ubicación donde el Assembly se guardó.If the dynamic Assembly is saved to disk, subsequent loads will get grants based on policies associated with the location where the Assembly was saved.

Este método solo debe usarse para definir un ensamblado dinámico en el dominio de aplicación actual.This method should only be used to define a dynamic assembly in the current application domain. Para obtener más información, consulte el Load(AssemblyName) sobrecarga del método.For more information, see the Load(AssemblyName) method overload.

Las solicitudes de permisos especificadas para requiredPermissions, optionalPermissions, y refusedPermissions no se usan a menos que el ensamblado dinámico se ha guardado y vuelve a cargar en memoria.The permission requests specified for requiredPermissions, optionalPermissions, and refusedPermissions are not used unless the dynamic assembly has been saved and reloaded into memory. Para especificar las solicitudes de permiso para un ensamblado transitorio que nunca se guarda en disco, use una sobrecarga de la DefineDynamicAssembly método que especifica la evidencia como solicitado así como los permisos y proporcionar un Evidence objeto.To specify permission requests for a transient assembly that is never saved to disk, use an overload of the DefineDynamicAssembly method that specifies evidence as well as requested permissions, and supply an Evidence object.

Las solicitudes de permisos especificadas para requiredPermissions, optionalPermissions, y refusedPermissions sólo se utilizan si evidence también se proporciona, o si el ensamblado dinámico se guarda y vuelve a cargar en memoria.The permission requests specified for requiredPermissions, optionalPermissions, and refusedPermissions are used only if evidence is also supplied, or if the dynamic assembly is saved and reloaded into memory.

Nota

Durante el desarrollo de código que emite ensamblados dinámicos, se recomienda que incluya SecurityPermissionFlag.SkipVerification en refusedPermissions.During the development of code that emits dynamic assemblies, it is recommended that you include SecurityPermissionFlag.SkipVerification in refusedPermissions. Incluyendo SkipVerification en el refusedPermissions parámetro garantiza que se debe comprobar el código MSIL.Including SkipVerification in the refusedPermissions parameter ensures that the MSIL is verified. Una limitación de esta técnica es que también hace que SecurityException se produce cuando se usa con el código que solicita plena confianza.A limitation of this technique is that it also causes SecurityException to be thrown when used with code that demands full trust.

Solo de plena confianza para los llamadores pueden suministrar sus evidence al definir un dinámico Assembly.Only fully trusted callers can supply their evidence when defining a dynamic Assembly. El tiempo de ejecución se asignará el Evidence a través de la directiva de seguridad para determinar los permisos concedidos.The runtime will map the Evidence through the security policy to determine the granted permissions. Los llamadores deben suministrar un valor null de confianza parcial evidence.Partially trusted callers must supply a null evidence. Si evidence es null, el tiempo de ejecución copia los conjuntos de permisos, es decir, actual otorgar y denegar los conjuntos, desde el llamador Assembly a dinámico Assembly que se está definiendo y marca la directiva como resuelta.If evidence is null, the runtime copies the permission sets, that is, the current grant and deny sets, from the caller's Assembly to the dynamic Assembly being defined and marks policy as resolved.

Si el dinámico Assembly está guardado en el disco, carga posteriores obtendrán las concesiones en función de las directivas asociadas a la ubicación donde el Assembly se guardó.If the dynamic Assembly is saved to disk, subsequent loads will get grants based on policies associated with the location where the Assembly was saved.

Este método solo debe usarse para definir un ensamblado dinámico en el dominio de aplicación actual.This method should only be used to define a dynamic assembly in the current application domain.

Utilice esta sobrecarga del método para especificar atributos que no funcionan correctamente a menos que se aplican cuando se crea un ensamblado dinámico.Use this method overload to specify attributes that do not work correctly unless they are applied when a dynamic assembly is created. Por ejemplo, atributos, como seguridad SecurityTransparentAttribute y SecurityCriticalAttribute no funcionan correctamente si se agregan una vez creado un ensamblado dinámico.For example, security attributes such as SecurityTransparentAttribute and SecurityCriticalAttribute do not work correctly if they are added after a dynamic assembly has been created.

Si isSynchronized es true, los métodos siguientes de resultante AssemblyBuilder se sincronizarán: DefineDynamicModule, DefineResource, AddResourceFile, GetDynamicModule, SetEntryPoint, y Save.If isSynchronized is true, the following methods of the resulting AssemblyBuilder will be synchronized: DefineDynamicModule, DefineResource, AddResourceFile, GetDynamicModule, SetEntryPoint, and Save. Si dos de estos métodos se llaman en subprocesos diferentes, uno se bloqueará hasta que se complete la otra.If two of these methods are called on different threads, one will block until the other is completed.

Comentarios

Utilice esta sobrecarga del método para especificar atributos que no funcionan correctamente a menos que se aplican cuando se crea un ensamblado dinámico.Use this method overload to specify attributes that do not work correctly unless they are applied when a dynamic assembly is created. Por ejemplo, atributos, como seguridad SecurityTransparentAttribute y SecurityCriticalAttribute no funcionan correctamente si se agregan una vez creado un ensamblado dinámico.For example, security attributes such as SecurityTransparentAttribute and SecurityCriticalAttribute do not work correctly if they are added after a dynamic assembly has been created.

Este método debe usarse únicamente para definir un ensamblado dinámico en el dominio de aplicación actual.This method should be used only to define a dynamic assembly in the current application domain.

Ejemplos

El ejemplo siguiente se muestra el DefineDynamicAssembly método y el AssemblyResolve eventos.The following sample demonstrates the DefineDynamicAssembly method and the AssemblyResolve event.

En primer lugar, el ejemplo de código se intenta crear una instancia de MyDynamicType mediante una llamada a la CreateInstance método con un nombre de ensamblado no válido y detecta la excepción resultante.First, the code example tries to create an instance of MyDynamicType by calling the CreateInstance method with an invalid assembly name, and catches the resulting exception.

El ejemplo de código, a continuación, agrega un controlador de eventos para el AssemblyResolve eventos y vuelva a intenta crear una instancia deMyDynamicType.The code example then adds an event handler for the AssemblyResolve event, and again tries to create an instance ofMyDynamicType. Durante la llamada a CreateInstance, el AssemblyResolve evento se desencadena para el ensamblado no válido.During the call to CreateInstance, the AssemblyResolve event is raised for the invalid assembly. El controlador de eventos crea un ensamblado dinámico que contiene un tipo denominado MyDynamicType, proporciona el tipo de un constructor sin parámetros y devuelve el nuevo ensamblado dinámico.The event handler creates a dynamic assembly that contains a type named MyDynamicType, gives the type a parameterless constructor, and returns the new dynamic assembly. La llamada a CreateInstance , a continuación, finaliza correctamente y el constructor para MyDynamicType muestra un mensaje en la consola.The call to CreateInstance then finishes successfully, and the constructor for MyDynamicType displays a message at the console.

Comentarios

Solo de plena confianza para los llamadores pueden suministrar sus evidence al definir un dinámico Assembly.Only fully trusted callers can supply their evidence when defining a dynamic Assembly. El tiempo de ejecución se asignará el Evidence a través de la directiva de seguridad para determinar los permisos concedidos.The runtime will map the Evidence through the security policy to determine the granted permissions. Los llamadores deben suministrar un valor null de confianza parcial evidence.Partially trusted callers must supply a null evidence. Si evidence es null, el tiempo de ejecución copia los conjuntos de permisos, es decir, actual otorgar y denegar los conjuntos, desde el llamador Assembly a dinámico Assembly que se está definiendo y marca la directiva como resuelta.If evidence is null, the runtime copies the permission sets, that is, the current grant and deny sets, from the caller's Assembly to the dynamic Assembly being defined and marks policy as resolved.

Si el dinámico Assembly está guardado en el disco, carga posteriores obtendrán las concesiones en función de las directivas asociadas a la ubicación donde el Assembly se guardó.If the dynamic Assembly is saved to disk, subsequent loads will get grants based on policies associated with the location where the Assembly was saved.

Ejemplos

Ejemplo de código siguiente muestra cómo crear un ensamblado dinámico que tiene el SecurityTransparentAttribute.The following code sample shows how to create a dynamic assembly that has the SecurityTransparentAttribute. El atributo debe especificarse como un elemento de una matriz de CustomAttributeBuilder objetos.The attribute must be specified as an element of an array of CustomAttributeBuilder objects.

El primer paso para crear el CustomAttributeBuilder es obtener un constructor para el atributo.The first step in creating the CustomAttributeBuilder is to obtain a constructor for the attribute. El constructor no tiene parámetros, por lo que la GetConstructor se llama al método con una matriz vacía de Type objetos que representan los tipos de los parámetros.The constructor has no parameters, so the GetConstructor method is called with an empty array of Type objects to represent the types of the parameters. El segundo paso consiste en pasar resultante ConstructorInfo objeto al constructor para la CustomAttributeBuilder (clase), junto con una matriz vacía de tipo Object para representar los argumentos.The second step is to pass the resulting ConstructorInfo object to the constructor for the CustomAttributeBuilder class, together with an empty array of type Object to represent the arguments.

Resultante CustomAttributeBuilder , a continuación, se pasa a la DefineDynamicAssembly método como el único elemento de una matriz.The resulting CustomAttributeBuilder is then passed to the DefineDynamicAssembly method as the only element of an array.

El código de ejemplo define un módulo y un tipo en el nuevo ensamblado dinámico y, a continuación, muestra los atributos del ensamblado.The example code defines a module and a type in the new dynamic assembly, and then displays the assembly's attributes.

using namespace System;
using namespace System::Reflection;

    // 
    // SecurityTransparentAttribute has a parameterless constructor, 
    // which is retrieved by passing an array of empty types for the
    // constructor's parameter types. The CustomAttributeBuilder is 
    // then created by passing the ConstructorInfo and an empty array
    // of objects to represent the parameters.
    //
    ConstructorInfo^ transparentCtor = 
        SecurityTransparentAttribute::typeid->GetConstructor(
            Type::EmptyTypes);
    CustomAttributeBuilder^ transparent = gcnew CustomAttributeBuilder(
        transparentCtor,
        gcnew array<Object^> {} );
      
    // Create a dynamic assembly using the attribute. The attribute is

Utilice esta sobrecarga del método para especificar atributos que no funcionan correctamente a menos que se aplican cuando se crea un ensamblado dinámico.Use this method overload to specify attributes that do not work correctly unless they are applied when a dynamic assembly is created. Por ejemplo, atributos, como seguridad SecurityTransparentAttribute y SecurityCriticalAttribute no funcionan correctamente si se agregan una vez creado un ensamblado dinámico.For example, security attributes such as SecurityTransparentAttribute and SecurityCriticalAttribute do not work correctly if they are added after a dynamic assembly has been created.

Este método debe usarse únicamente para definir un ensamblado dinámico en el dominio de aplicación actual.This method should be used only to define a dynamic assembly in the current application domain. Para obtener más información acerca de esta restricción, consulte el Load(AssemblyName) sobrecarga del método.For more information about this restriction, see the Load(AssemblyName) method overload.

Esta sobrecarga del método se introdujo en la .NET Framework 3,5.NET Framework 3.5.This method overload is introduced in the .NET Framework 3,5.NET Framework 3.5.

Nota

Durante el desarrollo de código que emite ensamblados dinámicos, se recomienda que use una sobrecarga de la DefineDynamicAssembly método que especifica la evidencia y permisos, proporcione la evidencia que desea que el ensamblado dinámico tiene e incluir SecurityPermissionFlag.SkipVerification en refusedPermissions.During the development of code that emits dynamic assemblies, it is recommended that you use an overload of the DefineDynamicAssembly method that specifies evidence and permissions, supply the evidence you want the dynamic assembly to have, and include SecurityPermissionFlag.SkipVerification in refusedPermissions. Incluyendo SkipVerification en el refusedPermissions parámetro garantiza que se debe comprobar el código MSIL.Including SkipVerification in the refusedPermissions parameter ensures that the MSIL is verified. Una limitación de esta técnica es que también hace que SecurityException se produce cuando se usa con el código que solicita plena confianza.A limitation of this technique is that it also causes SecurityException to be thrown when used with code that demands full trust.
