Updated: September 2009

Returns an interface mapping for the specified interface type.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
[ComVisibleAttribute(true)]
public virtual InterfaceMapping GetInterfaceMap(
	Type interfaceType
)

Parameters

interfaceType
Type: System.Type

The Type of the interface of which to retrieve a mapping.

Return Value

Type: System.Reflection.InterfaceMapping
An InterfaceMapping object representing the interface mapping for interfaceType.

Implements

_Type.GetInterfaceMap(Type)
ExceptionCondition
ArgumentException

The interfaceType parameter does not refer to an interface.

ArgumentNullException

interfaceType is null.

InvalidOperationException

The current Type represents a generic type parameter; that is, IsGenericParameter is true.

NotSupportedException

The invoked method is not supported in the base class. Derived classes must provide an implementation.

The interface map denotes how an interface is mapped into the actual methods on a class that implements that interface.

Important noteImportant Note:

This method does not return a correct mapping when the current type is an array type and interfaceType is a generic interface type. In the current release, there is no way to obtain this mapping with managed reflection.

If the current Type represents a constructed generic type, type parameters are replaced by the appropriate type arguments in the elements of the InterfaceMapping returned by this method.
