的含义（）=>操作员在C＃中，如果存在
问题描述：
我这里读了这个有趣的线上，由乔恩飞碟双向的答案。
I read this interesting line here, in an answer by Jon Skeet.
有趣的线是这个，他在那里使用委托主张：
The interesting line is this, where he advocated using a delegate:
Log.Info("I did something: {0}", () => action.GenerateDescription());
问题是，这是什么（）=>运营商，我不知道？我试图谷歌搜索，但因为它是由符号的谷歌不可能有很大帮助，真的。难道我尴尬想念这里的东西吗？
Question is, what is this ()=> operator, I wonder? I tried Googling it but since it's made of symbols Google couldn't be of much help, really. Did I embarrassingly miss something here?
答
此介绍不带参数的lambda函数（匿名委托），它相当于基本上速记为：
This introduces a lambda function (anonymous delegate) with no parameters, it's equivalent to and basically short-hand for:
delegate void () { return action.GenerateDescription(); }
您还可以添加参数，这样：
You can also add parameters, so:
(a, b) => a + b
这是大致相当于：
delegate int (int a, int b) { return a + b; }
