C#运算符重载用法实例分析

本文实例讲述了c#运算符重载用法。分享给大家供大家参考。具体分析如下：

public class plane {
   public virtual double topspeed() { return 300.0d;}
   public static bool operator>(plane one, plane two) {  
     return one.topspeed() > two.topspeed();
   }
   public static bool operator<(plane one, plane two) {  
     return one.topspeed() < two.topspeed();
   }
  }
  class jet : plane {
   public override double topspeed() { return 900.0d; }
   public override string tostring() { return "i'm a jet"; }
  }
   class airport {
   [stathread]
   static void main(string[] args) {
     plane plane = new jet();
     console.writeline("plane's top speed: {0}",plane.topspeed());
     jet jet = new jet();
     console.writeline("jet's top speed: {0}",jet.topspeed());
     console.writeline("plane > jet = {0}", plane > jet);
     console.readline();
   }
  }

希望本文所述对大家的c#程序设计有所帮助。
