 static Guid GenerateGuidForType(Type ^ type);

public static Guid GenerateGuidForType(Type type);

[System.Security.SecurityCritical]
public static Guid GenerateGuidForType(Type type);

[<System.Security.SecurityCritical>]
static member GenerateGuidForType : Type -> Guid

Public Shared Function GenerateGuidForType (type As Type) As Guid

Parameters

type: Type

The type to generate a GUID for.

Returns

Guid

An identifier for the specified type.

Attributes: SecurityCriticalAttribute

Remarks

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.
