This attribute is used to specify the GUID of assemblies, modules, or types you expose to COM. If you don't use this attribute to specify a GUID, one is automatically generated. When you apply this attribute, use its full name ( [GuidAttribute( )] rather than [Guid( )] ) to avoid clashes with the System.Guid type. public sealed class GuidAttribute : Attribute { // Public Constructors public GuidAttribute (string guid ); // Public Instance Properties public string Value {get; } } HierarchySystem.Object System.Attribute GuidAttribute Valid OnAssembly, Class, Struct, Enum, Interface, Delegate |
