Marshal.GenerateGuidForType Method

Returns the globally unique identifier (GUID) for the specified type, or generates a GUID using the algorithm used by the Type Library Exporter (Tlbexp.exe).

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

public static Guid GenerateGuidForType(
	Type type
)

Parameters

type
Type: System.Type
The type to generate a GUID for.

Return Value

Type: System.Guid
An identifier for the specified type.

If the type has a GUID in the metadata, it is returned. Otherwise, a GUID is automatically generated. You can use this method to programmatically determine the COM GUID for any managed type, including COM-invisible types. Class interfaces are the only exception because they do not correspond to a managed type. GenerateGuidForType provides the same functionality as the Type.GUID property.
