GuidAttribute Class
Assembly: mscorlib (in mscorlib.dll)
'Declaration <ComVisibleAttribute(True)> _ <AttributeUsageAttribute(AttributeTargets.Assembly Or AttributeTargets.Class Or AttributeTargets.Struct Or AttributeTargets.Enum Or AttributeTargets.Interface Or AttributeTargets.Delegate, Inherited:=False)> _ Public NotInheritable Class GuidAttribute Inherits Attribute 'Usage Dim instance As GuidAttribute
/** @attribute ComVisibleAttribute(true) */ /** @attribute AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface|AttributeTargets.Delegate, Inherited=false) */ public final class GuidAttribute extends Attribute
ComVisibleAttribute(true) AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface|AttributeTargets.Delegate, Inherited=false) public final class GuidAttribute extends Attribute
You can apply this attribute to assemblies, interfaces, classes, enumerations, structures, or delegates, although the Type Library Importer (Tlbimp.exe) 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.
The following example demonstrates how to apply the GuidAttribute to a class that is exported to COM with a fixed GUID.
Imports System Imports System.Runtime.InteropServices <GuidAttribute("9ED54F84-A89D-4fcd-A854-44251E925F09")> _ Public Class SampleClass ' Insert class members here. End Class
import System.*;
import System.Runtime.InteropServices.*;
/** @attribute GuidAttribute("9ED54F84-A89D-4fcd-A854-44251E925F09")
*/
public class SampleClass
{
// Insert class members here.
}
import System import System.Runtime.InteropServices public GuidAttribute("9ED54F84-A89D-4fcd-A854-44251E925F09") class SampleClass{ // Insert class members here }
