.net 正确实现IDisposable

1. public class User : IDisposable
2. {
3. public int id { get; protected set; }
4. public string name { get; protected set; }
5. public string pass { get; protected set; }
7. public User(int UserID)
8. {
9. id = UserID;
10. }
11. public User(string Username, string Password)
12. {
13. name = Username;
14. pass = Password;
15. }
17. // Other functions go here...
19. public void Dispose()
20. {
21. // Clear all property values that maybe have been set
22. // when the class was instantiated
23. id = 0;
24. name = String.Empty;
25. pass = String.Empty;
26. }
27. }

在VS2012中，我的代码分析要求正确实现IDisposable，但我不确定我在这里做错了什么。
具体内容如下：
CA1063正确实现IDisposable在"User"上提供Dispose（bool）的可重写实现或将类型标记为密封。调用Dispose（false）应仅清除本机资源。调用Dispose（true）应同时清除托管资源和本机资源。stman User.cs 10

修改如下：

1. public class User : IDisposable
2. {
3. public int id { get; protected set; }
4. public string name { get; protected set; }
5. public string pass { get; protected set; }
7. public User(int userID)
8. {
9. id = userID;
10. }
11. public User(string Username, string Password)
12. {
13. name = Username;
14. pass = Password;
15. }
17. // Other functions go here...
19. public void Dispose()
20. {
21. Dispose(true);
22. GC.SuppressFinalize(this);
23. }
25. protected virtual void Dispose(bool disposing)
26. {
27. if (disposing)
28. {
29. // free managed resources
30. }
31. // free native resources if there are any.
32. }
33. }
