Marshal::GenerateGuidForType Method (Type^)

.NET Framework (current version)

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)

Syntax

C++

public:
[SecurityCriticalAttribute]
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.

Security

SecurityCriticalAttribute

requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
