TypeBuilder.GetMethod Method (Type, MethodInfo)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns the method of the specified constructed generic type that corresponds to the specified method of the generic type definition.

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

Syntax

'Declaration
Public Shared Function GetMethod ( _
    type As Type, _
    method As MethodInfo _
) As MethodInfo
public static MethodInfo GetMethod(
    Type type,
    MethodInfo method
)

Parameters

  • type
    Type: System.Type
    The constructed generic type whose method is returned.
  • method
    Type: System.Reflection.MethodInfo
    A method on the generic type definition of type, which specifies which method of type to return.

Return Value

Type: System.Reflection.MethodInfo
The method of type corresponding to method, which specifies a method belonging to the generic type definition of type.

Exceptions

Exception Condition
ArgumentException

method is a generic method that is not a generic method definition.

-or-

type does not represent a generic type.

-or-

type is not of type TypeBuilder.

-or-

The declaring type of method is not a generic type definition.

-or-

The declaring type of method is not the generic type definition of type.

Remarks

The GetMethod method provides a way to get a MethodInfo object that represents a method of a constructed generic type whose generic type definition is represented by a TypeBuilder object.

For example, suppose you have a TypeBuilder object that represents the type G<T> in C# syntax (G(Of T) in Visual Basic, generic <T> ref class G in C++) and a MethodBuilder object that represents a method T M() in C# syntax (Function M() As T in Visual Basic, T M() in C++) that is defined by G<T>. Suppose that G<T> has a generic method with type parameter U that creates an instance of the constructed type G<U> and calls method M on that instance. In order to emit the function call, you need a MethodInfo object that represents M on the constructed type — in other words, that returns type U rather than type T. To do this, first call the MakeGenericType method on the TypeBuilder object, specifying the GenericTypeParameterBuilder object that represents U as the type argument. Then call the GetMethod method with the return value of the MakeGenericType method as parameter type and the MethodBuilder object that represents T M() as parameter method. The return value is the MethodInfo object you need to emit the function call. The code example for the GetField method demonstrates a scenario similar to this.
