Summary

Enumerates the application elements to which it is valid to attach an attribute.

Description

AttributeTargets is used as a parameter for AttributeUsageAttribute to enable an attribute to be associated with one or more kinds of application elements.

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.

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() {
   }
}
