有人能解释一下匿名方法是C＃（在简单计算），并提供可能的例子，请

Could someone explain what anonymous methods are in C# (in simplistic terms) and provide examples in possible please

推荐答案

匿名方法被引入到C＃2为，而无需编写一个单独的方法创建委托实例的方法。他们可以的捕捉的封闭的方法中的局部变量，使他们的一种形式的关闭的。

Anonymous methods were introduced into C# 2 as a way of creating delegate instances without having to write a separate method. They can capture local variables within the enclosing method, making them a form of closure.

这是匿名方法看起来是这样的：

An anonymous method looks something like:

delegate (int x) { return x * 2; }

和必须转换到特定的委托类型，例如通过分配：

and must be converted to a specific delegate type, e.g. via assignment:

Func<int, int> foo = delegate (int x) { return x * 2; };

...或订阅的事件处理程序：

... or subscribing an event handler:

button.Click += delegate (object sender, EventArgs e) {
    // React here
};

需要注意的是lamdba EX pressions在C＃3具有的几乎的完全取代匿名方法（虽然他们仍然是完全有效的，当然）。匿名方法和lambda EX pressions都被统称为的匿名函数的。

Note that lamdba expressions in C# 3 have almost completely replaced anonymous methods (although they're still entirely valid of course). Anonymous methods and lambda expressions are collectively described as anonymous functions.
