是否可以在继承中进行方法重载 [英] Is it possible to do method overloading in inheritance

问题描述

是否可以使用c#

Hi,
Is it possible to do method overloading in inheritance using c#

推荐答案

在继承中进行方法重载?这个问题的答案是肯定的
参见以下示例

Anser to this question is yes
see below example

class Base
  {
      public virtual void Foo(int x)
      {
          Console.WriteLine("Base.Foo(int)");
      }
  }

  class Derived : Base
  {
      public override void Foo(int x)
      {
          Console.WriteLine("Derived.Foo(int)");
      }

      public void Foo(string o)
      {
          Console.WriteLine("Derived.Foo(string)");
      }
  }

  class Test
  {
      static void Main()
      {
          Derived d = new Derived();
          int i = 10;
          d.Foo(i);  // it prints ("Derived.Foo(int)"
          d.Foo("Hii");//it prints ("Derived.Foo(string)"
          Console.ReadKey();
      }
  }

会有什么疑问?让我以更一般的方式来解释它.

重载"在技术上没有任何意义，除了命名和方法解析之外，什么也没有影响.但这只是允许不同方法的相同名称.术语超载"非常令人困惑，因为没有什么是真正的超载".实际上，这是唯一的问题.

What would be a reason for doubt? Let me explain it in a bit more general way.

"Overloading" technologically means nothing and effects nothing except naming and hence method resolution. This is nothing but allowed identical names of the different methods. The term "overloading" it very confusing, because nothing is really "loaded". That''s the only problem, in fact.
