Examples

The following example demonstrates how to apply the GuidAttribute to a class that is exported to COM with a fixed GUID.

using namespace System;
using namespace System::Runtime::InteropServices;


[GuidAttribute("9ED54F84-A89D-4fcd-A854-44251E925F09")]
public ref class SampleClass
{
	// Insert class members here.
};

using System;
using System.Runtime.InteropServices;


[GuidAttribute("9ED54F84-A89D-4fcd-A854-44251E925F09")]
public class SampleClass 
{
    // Insert class members here.
}

Imports System
Imports System.Runtime.InteropServices


 <GuidAttribute("9ED54F84-A89D-4fcd-A854-44251E925F09")> _
 Public Class SampleClass
     ' Insert class members here.
 End Class

Remarks

You can apply this attribute to assemblies, interfaces, classes, enumerations, structures, or delegates, although the Tlbimp.exe (Type Library Importer) can apply it for you when it imports a type library.

The string passed to the attribute must be in a format that is an acceptable constructor argument for the type Guid. To avoid conflicts with the type Guid, use the long name GuidAttribute explicitly. Only use an explicit GUID when a type must have a specific GUID. If the attribute is omitted, a GUID is assigned automatically.
