Lambda expression for multiple parameters

Question

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

example

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    } } 

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  } 

How can multi parameters be expressed using Lambda expressions?

Answer 1

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

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;
