C# 委托-lambda表达式

// 匿名方法
Func<int, int, string> func2 =
delegate(int a, int b)
{
return a+"+"+b+"等于几？" + Environment.NewLine +(a+b).ToString();
};

// Lambda表达式
Func<int, int, string> func3 =
(a, b) => { return a + "+" + b + "等于几？" + Environment.NewLine + (a + b).ToString(); };

两段代码是等效的

func2(1,2) == func3(1,3)
