Type.GetInterfaceMap Method

Returns an interface mapping for the specified interface type.

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

abstract GetInterfaceMap : 
        interfaceType:Type -> InterfaceMapping 
override GetInterfaceMap : 
        interfaceType:Type -> InterfaceMapping


Type: System.Type

The interface type to retrieve a mapping for.

Return Value

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




interfaceType is not implemented by the current type.


The interfaceType parameter does not refer to an interface.


interfaceType is a generic interface, and the current type is an array type.


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


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


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 members on a class that implements that interface.

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.

The following example calls the GetInterfaceMap method to determine how the IFormatProvider interface maps to CultureInfo methods, and how the IAppDomainSetup interface maps to AppDomainSetup properties. Note that, because the IAppDomainSetup interface defines a set of properties, the returned InterfaceMapping object includes separate MethodInfo objects for a property's get and set accessors.
