类或结构可以通过使用显示接口实现来避免将成员声明为 public. 显示接口成员实现使用完全限定的接口成员名。例如 EidtBox类可以使用显示接口成员实现来实现IControl的Paint方法和IDataBind的Bind方法。

   1:      public class Binder

   2:      {

   3:          //

   4:      }

   5:      public interface IControl

   6:      {

   7:          void Paint();

   8:      }

   9:      public interface IDataBind

  10:      {

  11:          void Bind(Binder b);

  12:      }

  13:      public class EditBox : IControl,IDataBind

  14:      {

  15:          #region IControl Members

  16:   

  17:          public void IControl.Paint()

  18:          {

  19:              throw new NotImplementedException();

  20:          }

  21:   

  22:          #endregion

  23:   

  24:          #region IDataBind Members

  25:   

  26:          public void IDataBind.Bind(Binder b)

  27:          {

  28:              throw new NotImplementedException();

  29:          }

  30:   

  31:          #endregion

  32:      }

调用方法：

   1:          static void Main(string[] args)

   2:          {

   3:              IControl editBox = new EditBox();

   4:              editBox.Paint();//正确

   5:              EditBox edit = new EditBox();

   6:              edit.Paint();//错误，找不到方法

   7:          }
