TypeLibTypeAttribute Class

Contains the TYPEFLAGS that were originally imported for this type from the COM type library.

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

[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface, Inherited = false)]
public sealed class TypeLibTypeAttribute : Attribute

The Type Library Importer (Tlbimp.exe) applies this attribute to classes or interfaces.

This attribute is applied when a type library is imported and should never be changed. It is only applied when the method's TYPEFLAGS evaluate to non-zero. The attribute is designed to be used by tools that need to know how the original TYPEFLAGS were set. The common language runtime does not use this attribute.

The following example demonstrates how to get the TypeLibTypeAttribute value of a class or interface.

using System;
using System.Runtime.InteropServices;

namespace B
{
	class ClassB	
	{
		public static bool IsHiddenInterface( Type InterfaceType )
		{
			object[] InterfaceAttributes = InterfaceType.GetCustomAttributes( typeof( TypeLibTypeAttribute ), false );
			if( InterfaceAttributes.Length > 0 )
			{
				TypeLibTypeAttribute tlt = ( TypeLibTypeAttribute ) InterfaceAttributes[0];
				TypeLibTypeFlags  flags = tlt.Value;
				return ( flags & TypeLibTypeFlags.FHidden ) != 0; 
			}
			return false;
		}
	}
}
