Namespace:  System.Reflection.Emit
Assembly:  mscorlib (in mscorlib.dll)

member DefineMethod : 
        name:string * 
        attributes:MethodAttributes *

        parameterTypes:Type[] -> MethodBuilder


Type: System.String

Return Value

Type: System.Reflection.Emit.MethodBuilder
A MethodBuilder representing the newly defined method.


The length of name is zero.


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


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


The type was previously created using CreateType.


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

The following code sample demonstrates the use of DefineMethod to set a constructor's particular signature and attributes on a dynamic type and to return a corresponding MethodBuilder for MSIL population.

No code example is currently available or this language may not be supported.
