多个参数的Lambda表达式 [英] Lambda expression for multiple parameters

问题描述

我了解到lambda表达式本质上是一种内联委托声明，以防止执行额外的步骤

I understand a lambda expression is in essence an inline delegate declaration to prevent the extra step

示例

delegate int Square(int x)
public class Program
{
   static void Main(String[] args)
   {
      Square s = x=>x*x;
      int result = s(5);
      Console.WriteLine(result); // gives 25
   }
}

一个人如何将Lambda表达式应用于多个参数 像

How does one apply Lambda expressions to multi parameters Something like

 delegate int Add(int a, int b)
 static void Main(String[] args)
 {
    // Lambda expression goes here
 }

如何使用Lambda表达式表达多个参数?

How can multi parameters be expressed using Lambda expressions?

推荐答案

您必须了解 Func 行为，其中最后一个参数始终是 output 或 result

You must understand the Func behavior, where the last parameter is always the output or result

Func< 1，2，outPut>

Func<1, 2, outPut>

Func<int, int, int> Add = (x, y) => x + y;

Func<int, int, int> diff = (x, y) => x - y;

Func<int, int, int> multi = (x, y) => x * y;
