Retrieves the library identifier (LIBID) that is assigned to a type library when it was exported from the specified assembly.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.Reflection.Assembly
The assembly from which the type library was exported.
Return ValueType: System.Guid
The LIBID that is assigned to a type library when it is exported from the specified assembly.
When assemblies are exported to type libraries, the type library is assigned a LIBID. You can set the LIBID explicitly by applying the System.Runtime.InteropServices.GuidAttribute at the assembly level, or it can be generated automatically. The Tlbimp.exe (Type Library Importer) tool calculates a LIBID value based on the identity of the assembly. GetTypeLibGuid returns the LIBID that is associated with the GuidAttribute, if the attribute is applied. Otherwise, returns the calculated value. Alternatively, you can use the GetTypeLibGuid method to extract the actual LIBID from an existing type library.
See the Exported Assembly Conversion topic for more information about library identifiers.
