TypeLibFuncAttribute Class

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

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

[AttributeUsageAttribute(AttributeTargets.Method, Inherited = false)]
public sealed class TypeLibFuncAttribute : Attribute

The Type Library Importer (Tlbimp.exe) applies this attribute to methods.

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

The following example demonstrates how to get the TypeLibFuncAttribute value of a method.

using System;
using System.Reflection;
using System.Runtime.InteropServices;

namespace C
	class ClassC	
		public static bool IsHiddenMethod( MethodInfo mi )
			object[] MethodAttributes = mi.GetCustomAttributes( typeof( TypeLibFuncAttribute ), true);
			if( MethodAttributes.Length > 0 )
				TypeLibFuncAttribute tlf = ( TypeLibFuncAttribute )MethodAttributes[0];
				TypeLibFuncFlags  flags = tlf.Value;
				return ( flags & TypeLibFuncFlags.FHidden ) != 0; 
			return false;
