Not applicable.

Parameters

name

The name of the method. name cannot contain embedded nulls.

attributes

The attributes of the method.

callingConvention

The calling convention of the method.

returnType

The return type of the method.

returnTypeRequiredCustomModifiers

An array of types representing the required custom modifiers, such as IsConst, for the return type of the method. If the return type has no required custom modifiers, specify a null reference (Nothing in Visual Basic).

returnTypeOptionalCustomModifiers

An array of types representing the optional custom modifiers, such as IsConst, for the return type of the method. If the return type has no optional custom modifiers, specify a null reference (Nothing in Visual Basic).

parameterTypes

The types of the parameters of the method.

parameterTypeRequiredCustomModifiers

An array of arrays of types. Each array of types represents the required custom modifiers for the corresponding parameter, such as IsConst. If a particular parameter has no required custom modifiers, specify a null reference (Nothing in Visual Basic) instead of an array of types. If none of the parameters have required custom modifiers, specify a null reference (Nothing in Visual Basic) instead of an array of arrays.

parameterTypeOptionalCustomModifiers

An array of arrays of types. Each array of types represents the optional custom modifiers for the corresponding parameter, such as IsConst. If a particular parameter has no optional custom modifiers, specify a null reference (Nothing in Visual Basic) instead of an array of types. If none of the parameters have optional custom modifiers, specify a null reference (Nothing in Visual Basic) instead of an array of arrays.

Return Value

A MethodBuilder object representing the newly added method.

Exception typeCondition

ArgumentException

The length of name is zero.

-or-

The type of the parent of this method is an interface, and this method is not virtual (Overridable in Visual Basic).

-or-

The size of parameterTypeRequiredCustomModifiers or parameterTypeOptionalCustomModifiers does not equal the size of parameterTypes.

ArgumentNullException

name is a null reference (Nothing in Visual Basic).

InvalidOperationException

The type was previously created using CreateType.

-or-

For the current dynamic type, the IsGenericType property is true, but the IsGenericTypeDefinition property is false.

Use this overload if you need to specify custom modifiers. 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.

NoteNote:

For more information on custom modifiers, see the ECMA Partition II Metadata documentation. Partition II documentation is available online at http://msdn.microsoft.com/net/ecma/ and http://www.ecma-international.org/publications/standards/Ecma-335.htm.
