Example

The following example demonstrates how AttributeTargets can be used with AttributeUsageAttribute so that a user-defined attribute class, Author, can be applied to structures and classes. The Author attribute is then applied to a class. There is no output.

C# Example

using System;

[AttributeUsageAttribute(AttributeTargets.Class|
                         AttributeTargets.Struct)]
public class Author : Attribute {

   public Author(string Name) {
 
     this.name = Name; }
     string name;
   }

[Author("John Q Public")]
class JohnsClass {

   public static void Main() {
   }
}
