刚开始学习c#  帮忙看看下面一段代码哪里错了
using System;
delegate void EatDelegate(string food);
class myDelegate
{
static void zsEat(string food)
{
      Console.WriteLine("张三吃"+food);
}
static void lsEat(string food)
{
      Console.WriteLine("李四吃"+food );
}
static void wwEat(string food)
{
      Console.WriteLine("王五吃"+food);
}

static void Main()
{
      EatDelegate zs = new EatDelegate(zsEat);
      EatDelegate ls = new EatDelegate(lsEat );
      EatDelegate ww = new EatDelegate(wwEat );
      EatDelegate eatChain;
      eatChain = zs + ls + ww;
      eatChain =("西瓜");
      Console.ReadKey();
}
}

谢谢了！！！！！！！

main 方法中改为

EatDelegate e1 = zsEat;
         EatDelegate e2 = lsEat;
         EatDelegate e3 = wwEat;
         e1("西瓜");
         e2("西瓜");
         e3("西瓜");
         Console.Read();

也有更简单的方法

在添加一个方法

static void run(string food , EatDelegate e)
      {
         e(food);
      }

然后MAIN方法改为

run("西瓜",zsEat);
         Console.Read();
