Ejemplos

En el ejemplo de código siguiente se define un método genérico denominado DemoMethod, cuyo tipo de parámetro y tipo de valor devuelto se especifican mediante sus parámetros de tipo genérico.The following code example defines a generic method named DemoMethod whose parameter type and return type are specified by its generic type parameters. El método se define sin una firma, mediante la Convención de llamada estándar.The method is defined without a signature, using the standard calling convention. El método MethodBuilder.DefineGenericParameters se usa para convertir DemoMethod en un método genérico y, a continuación, se usan los parámetros de tipo recién definidos para la firma y el tipo de valor devuelto.The MethodBuilder.DefineGenericParameters method is used to make DemoMethod a generic method, and the newly defined type parameters are then used for the signature and return type.

Comentarios

Utilice esta sobrecarga del método cuando no conozca la firma del método en el momento de definir el método.Use this method overload when you do not know the method signature at the time you define the method. Por ejemplo, los parámetros de tipo genérico del método pueden especificar los tipos de parámetro y el tipo de valor devuelto de un método genérico, que deben definirse después de que el método se haya agregado al tipo.For example, the parameter types and return type of a generic method might be specified by the method's generic type parameters, which must be defined after the method has been added to the type. Los parámetros y el tipo de valor devuelto del método se pueden establecer posteriormente con el método MethodBuilder.SetSignature.The parameters and return type of the method can be set later using the MethodBuilder.SetSignature method.

Esta sobrecarga del método define un método con CallingConventions.Standard.This method overload defines a method with CallingConventions.Standard. Si necesita definir un método sin una firma, con una Convención de llamada diferente, utilice la sobrecarga del método DefineMethod(String, MethodAttributes, CallingConventions).If you need to define a method without a signature, with a different calling convention, use the DefineMethod(String, MethodAttributes, CallingConventions) method overload.

Comentarios

Utilice esta sobrecarga si necesita especificar modificadores personalizados.Use this overload if you need to specify custom modifiers. Si necesita especificar modificadores personalizados después de haber creado el método, como lo haría, por ejemplo, con un método genérico cuyos tipos de parámetro se especifican mediante sus parámetros de tipo genérico, puede usar las sobrecargas del método DefineMethod(String, MethodAttributes) o DefineMethod(String, MethodAttributes, CallingConventions) para definir el método y a continuación, use el método MethodBuilder.SetSignature para definir el parámetro y los tipos de valor devuelto con modificadores personalizados.If you need to specify custom modifiers after the method has been created, as you would, for example, with a generic method whose parameter types are specified by its generic type parameters, you can use the DefineMethod(String, MethodAttributes) or DefineMethod(String, MethodAttributes, CallingConventions) method overloads to define the method and then use the MethodBuilder.SetSignature method to define the parameter and return types with custom modifiers.
