Type.GetInterface Method (String, Boolean)

.NET Framework 1.1

When overridden in a derived class, searches for the specified interface, specifying whether to do a case-sensitive search.

[Visual Basic]
Overloads Public MustOverride Function GetInterface( _
   ByVal name As String, _
   ByVal ignoreCase As Boolean _
) As Type
[C#]
public abstract Type GetInterface(
 string name,
 bool ignoreCase
);
[C++]
public: virtual Type* GetInterface(
 String* name,
 bool ignoreCase
) = 0;
[JScript]
public abstract function GetInterface(
   name : String,
 ignoreCase : Boolean
) : Type;

Parameters

name

The String containing the name of the interface to get.

ignoreCase

true to perform a case-insensitive search for name.

-or-

false to perform a case-sensitive search for name.

Return Value

A Type object representing the interface with the specified name, implemented or inherited by the current Type, if found; otherwise, a null reference (Nothing in Visual Basic).

Exceptions

Exception Type	Condition
ArgumentNullException	name is a null reference (Nothing in Visual Basic).
