c#3.0表达式的含义()=>

问题描述：

此表达式()=>"的含义是什么.我看过它在构造函数中使用过:

What is the meaning of this expression " () =>". I have seen it used in a constructor:

return new MyItem(itemId, () => MyFunction(myParam));

谢谢

答

这是不带参数的委托，写为lambda.与

It's a delegate without parameters, written as a lambda. Same as:

return new MyItem(itemId, delegate() {return MyFunction(myParam); });
