Type::GetInterface Method (String, Boolean)

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

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

public:
virtual Type^ GetInterface(
	String^ name, 
	bool ignoreCase
) abstract

Parameters

name
Type: System::String

The string containing the name of the interface to get. For generic interfaces, this is the mangled name.

ignoreCase
Type: System::Boolean

true to ignore the case of that part of name that specifies the simple interface name (the part that specifies the namespace must be correctly cased).

-or-

false to perform a case-sensitive search for all parts of name.

Return Value

Type: System::Type
An object representing the interface with the specified name, implemented or inherited by the current Type, if found; otherwise, nullptr.

Implements

_Type::GetInterface(String, Boolean)

ExceptionCondition
ArgumentNullException

name is nullptr.

AmbiguousMatchException

The current Type represents a type that implements the same generic interface with different type arguments.

The ignoreCase parameter applies only to the simple interface name, not to the namespace. The portion of name that specifies the namespace must have the correct case, or the interface will not be found. For example, the string "System.icomparable" finds the IComparable interface, but the string "system.icomparable" does not.

If the current Type represents a constructed generic type, this method returns the Type with the type parameters replaced by the appropriate type arguments.

If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the interface constraints and any interfaces inherited from class or interface constraints.

NoteNote

For generic interfaces, the name parameter is the mangled name, ending with a grave accent (`) and the number of type parameters. This is true for both generic interface definitions and constructed generic interfaces. For example, to find IExample<T> (IExample(Of T) in Visual Basic) or IExample<string> (IExample(Of String) in Visual Basic), search for "IExample`1".

The following code example uses the GetInterface(String, Boolean) method to perform a case-insensitive search of the Hashtable class for the IEnumerable interface.

The code example also demonstrates the GetInterface(String) method overload and the GetInterfaceMap method.

int main()
{
   Hashtable^ hashtableObj = gcnew Hashtable;
   Type^ objType = hashtableObj->GetType();
   array<MemberInfo^>^arrayMemberInfo;
   array<MethodInfo^>^arrayMethodInfo;
   try
   {
      // Get the methods implemented in 'IDeserializationCallback' interface.
      arrayMethodInfo = objType->GetInterface( "IDeserializationCallback" )->GetMethods();
      Console::WriteLine( "\nMethods of 'IDeserializationCallback' Interface :" );
      for ( int index = 0; index < arrayMethodInfo->Length; index++ )
         Console::WriteLine( arrayMethodInfo[ index ] );

      // Get FullName for interface by using Ignore case search.
      Console::WriteLine( "\nMethods of 'IEnumerable' Interface" );
      arrayMethodInfo = objType->GetInterface( "ienumerable", true )->GetMethods();
      for ( int index = 0; index < arrayMethodInfo->Length; index++ )
         Console::WriteLine( arrayMethodInfo[ index ] );

      //Get the Interface methods for 'IDictionary*' interface
      InterfaceMapping interfaceMappingObj;
      interfaceMappingObj = objType->GetInterfaceMap( IDictionary::typeid );
      arrayMemberInfo = interfaceMappingObj.InterfaceMethods;
      Console::WriteLine( "\nHashtable class Implements the following IDictionary Interface methods :" );
      for ( int index = 0; index < arrayMemberInfo->Length; index++ )
         Console::WriteLine( arrayMemberInfo[ index ] );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception : {0}", e );
   }
}
