Public NotInheritable Class TypeLibFuncAttribute
	Inherits Attribute
NameDescription
System_CAPS_pubmethod TypeLibFuncAttribute

Initializes a new instance of the TypeLibFuncAttribute class with the specified System.Runtime.InteropServicesTypeLibFuncFlags value.

System_CAPS_pubmethod TypeLibFuncAttribute

Initializes a new instance of the TypeLibFuncAttribute class with the specified System.Runtime.InteropServicesTypeLibFuncFlags value.

NameDescription
System_CAPS_pubproperty

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

System_CAPS_pubproperty
NameDescription
System_CAPS_pubmethod Equals

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod IsDefaultAttribute

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethod Match

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

Provides 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;
		}
	}
}

			Dim flags As TypeLibFuncFlags = tlf.Value
			Return (flags & TypeLibFuncFlags.FHidden) > 0
		End If
		Return False
	End Function

      if ( MethodAttributes->Length > 0 )
      {
         TypeLibFuncAttribute^ tlf = dynamic_cast<TypeLibFuncAttribute^>(MethodAttributes[ 0 ]);
         TypeLibFuncFlags flags = tlf->Value;
         return (flags & TypeLibFuncFlags::FHidden) != (TypeLibFuncFlags)0;
      }

      return false;
   }
