public object CreateInstanceFromAndUnwrap (string assemblyName, string typeName);
member this.CreateInstanceFromAndUnwrap : string * string -> obj
Public Function CreateInstanceFromAndUnwrap (assemblyName As String, typeName As String) As Object

Parameters

assemblyName
String String String String

The file name and path of the assembly that defines the requested type.

typeName
String String String String

The fully qualified name of the requested type, including the namespace but not the assembly, as returned by the FullName property.

Returns

The requested object, or null if typeName is not found.

Exceptions

The caller does not have sufficient permission to call this constructor.

assemblyName is not a valid assembly.

-or-

Version 2.0 or later of the common language runtime is currently loaded and assemblyName was compiled with a later version.

An assembly or module was loaded twice with two different evidences.

Remarks

This is a convenience method that combines CreateInstanceFrom and ObjectHandle.Unwrap. This method calls the default constructor for typeName.

Public Function CreateInstanceFromAndUnwrap (assemblyName As String, typeName As String, activationAttributes As Object()) As Object

Parameters

assemblyName
String String String String

The file name and path of the assembly that defines the requested type.

typeName
String String String String

The fully qualified name of the requested type, including the namespace but not the assembly (see the FullName property).

activationAttributes
Object[]

An array of one or more attributes that can participate in activation. Typically, an array that contains a single UrlAttribute object that specifies the URL that is required to activate a remote object.

This parameter is related to client-activated objects.Client activation is a legacy technology that is retained for backward compatibility but is not recommended for new development. Distributed applications should instead use Windows Communication Foundation.

Returns

The requested object, or null if typeName is not found.

Exceptions

The caller cannot provide activation attributes for an object that does not inherit from MarshalByRefObject.

The caller does not have sufficient permission to call this constructor.

assemblyName is not a valid assembly.

-or-

Version 2.0 or later of the common language runtime is currently loaded and assemblyName was compiled with a later version.

An assembly or module was loaded twice with two different evidences.

Parameters

assemblyFile
String String String String

The file name and path of the assembly that defines the requested type.

typeName
String String String String

The fully qualified name of the requested type, including the namespace but not the assembly, as returned by the FullName property.

ignoreCase
Boolean Boolean Boolean Boolean

A Boolean value specifying whether to perform a case-sensitive search or not.

bindingAttr
BindingFlags BindingFlags BindingFlags BindingFlags

A combination of zero or more bit flags that affect the search for the typeName constructor. If bindingAttr is zero, a case-sensitive search for public constructors is conducted.

binder
Binder Binder Binder Binder

An object that enables the binding, coercion of argument types, invocation of members, and retrieval of MemberInfo objects through reflection. If binder is null, the default binder is used.

args
Object[]

The arguments to pass to the constructor. This array of arguments must match in number, order, and type the parameters of the constructor to invoke. If the default constructor is preferred, args must be an empty array or null.

culture
CultureInfo CultureInfo CultureInfo CultureInfo

Culture-specific information that governs the coercion of args to the formal types declared for the typeName constructor. If culture is null, the CultureInfo for the current thread is used.

activationAttributes
Object[]

An array of one or more attributes that can participate in activation. Typically, an array that contains a single UrlAttribute object that specifies the URL that is required to activate a remote object.

This parameter is related to client-activated objects. Client activation is a legacy technology that is retained for backward compatibility but is not recommended for new development. Distributed applications should instead use Windows Communication Foundation.

Returns

The requested object, or null if typeName is not found.

Exceptions

The caller does not have sufficient permission to call this constructor.

assemblyName is not a valid assembly.

-or-

assemblyName was compiled with a later version of the common language runtime that the version that is currently loaded.
