The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Retrieves the library identifier (LIBID) of a type library.

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

Public Shared Function GetTypeLibGuid (
	typelib As ITypeLib
) As Guid


Type: System.Runtime.InteropServices.ComTypes.ITypeLib

The type library whose LIBID is to be retrieved.

Return Value

Type: System.Guid

The LIBID of the specified type library.

GetTypeLibGuid extracts the LIBID directly from an existing type library. This action differs from that of the Marshal.GetTypeLibGuidForAssembly method, which calculates what the LIBID should be based on the current assembly.
