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
)
public static Guid GenerateGuidForType (
	Type type
)
public static function GenerateGuidForType (
	type : Type
) : Guid
Not applicable.

Parameters

type

The Type to generate a GUID for.

Return Value

A Guid 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 since they do not correspond to a managed type. GenerateGuidForType provides the same functionality as the Type.GUID property.

NoteNote:

This method uses SecurityAction.LinkDemand to prevent it from being called from untrusted code; only the immediate caller is required to have SecurityPermissionAttribute.UnmanagedCode permission. If your code can be called from partially trusted code, do not pass user input to Marshal class methods without validation. For important limitations on using the LinkDemand member, see Demand vs. LinkDemand.
