GuidAttribute Class
Assembly: mscorlib (in mscorlib.dll)
[AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface|AttributeTargets.Delegate, Inherited=false)] [ComVisibleAttribute(true)] public sealed class GuidAttribute : Attribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface|AttributeTargets.Delegate, Inherited=false) */ /** @attribute ComVisibleAttribute(true) */ public final class GuidAttribute extends Attribute
AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface|AttributeTargets.Delegate, Inherited=false) ComVisibleAttribute(true) public final class GuidAttribute extends Attribute
Not applicable.
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.
using System; using System.Runtime.InteropServices; [GuidAttribute("9ED54F84-A89D-4fcd-A854-44251E925F09")] public class SampleClass { // Insert class members here. }
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 }
