Lambda表達式 簡化了匿名委托的使用,讓你讓代碼更加簡潔,優雅。據說它是微軟自c#1.0後新增的最重要的功能之一。
首先來看一下其發展

根據上面的發展歷程,可以感到Lambda表達式愈加簡化。
詳細介紹:



using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Lambda
{
class Program
{
static void Main(string[] args)
{
int sum = 0;
Func<int, int> f1 = x => 2 * x + 1;
Func<int, int, bool> f2 = (x, y) => x > y;
Func<string, int, string> f3 = (x, y) => x.Substring(y);
Func<int, int> f4 = (x) => sum += x;
Action a1 = () => { System.Console.WriteLine("HelloWorld"); };
Action <int> a2 = (x) => { System.Console.WriteLine(x); };
Action <bool> a3 = (x) => { System.Console.WriteLine(x); };
Action<string> a4 = (x) => { System.Console.WriteLine(x); };
for (int i = 1; i <= 10; i++ )
{
f4(i);
}
a2(sum);
a1();
a2(f1(1));
a3(f2(3, 5));
a4(f3("Zhengpengfei", 5));
System.Console.Read();
}
}
}
