TypeLibFuncAttribute Class

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

System.Object
  System.Attribute
    System.Runtime.InteropServices.TypeLibFuncAttribute

Namespace:  System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)
[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets.Method, Inherited = false)]
public sealed class TypeLibFuncAttribute : Attribute

The TypeLibFuncAttribute type exposes the following members.

  NameDescription
Public methodTypeLibFuncAttribute(Int16)Initializes a new instance of the TypeLibFuncAttribute class with the specified System.Runtime.InteropServices.TypeLibFuncFlags value.
Public methodTypeLibFuncAttribute(TypeLibFuncFlags)Initializes a new instance of the TypeLibFuncAttribute class with the specified System.Runtime.InteropServices.TypeLibFuncFlags value.

  NameDescription
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Public propertyValueGets the System.Runtime.InteropServices.TypeLibFuncFlags value for this method.

  NameDescription
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

The Tlbimp.exe (Type Library Importer) 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;
		}
	}
}
