Marshal.GetTypeLibGuid Method (UCOMITypeLib)

Note: This API is now obsolete.

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

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

[<ObsoleteAttribute("Use System.Runtime.InteropServices.Marshal.GetTypeLibGuid(ITypeLib pTLB) instead.",
static member GetTypeLibGuid : 
        pTLB:UCOMITypeLib -> Guid


Type: System.Runtime.InteropServices.UCOMITypeLib

The type library whose LIBID is to be retrieved.

Return Value

Type: System.Guid

The LIBID of the type library that the pTLB parameter points to.

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.
