命名方法委託的基礎引用

將命名方法分配給委託時，如果符合以下條件，它們將引用相同的基礎物件：

• 它們是同一個例項方法，在同一個類的例項上

• 它們是類中的靜態方法

  public class Greeter
  {
      public void WriteInstance()
      {
          Console.WriteLine("Instance");
      }
  
      public static void WriteStatic()
      {
          Console.WriteLine("Static");
      }
  }
  
  // ...
  
  Greeter greeter1 = new Greeter();
  Greeter greeter2 = new Greeter();
  
  Action instance1 = greeter1.WriteInstance;
  Action instance2 = greeter2.WriteInstance;
  Action instance1Again = greeter1.WriteInstance;
  
  Console.WriteLine(instance1.Equals(instance2)); // False
  Console.WriteLine(instance1.Equals(instance1Again)); // True
  
  Action @static = Greeter.WriteStatic;
  Action staticAgain = Greeter.WriteStatic;
  
  Console.WriteLine(@static.Equals(staticAgain)); // True
