C#Lambda表达式的用法
示例代码如下,控制台应用程序:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace LambdaExpressionDemo
{
delegate void AddHandler(int a, int b);
class Program
{
event AddHandler AddEvent;
static void Main(string[] args)
{
int x = 10;
int y = 5;
Program program = new Program();
program.AddEvent += new AddHandler(Program.program_AddEvent);
program.AddEvent += delegate(int a, int b)
{
Console.WriteLine("C# 2.0时代的事件处理方式");
Console.WriteLine(a + b);
};
program.AddEvent += (a, b) =>
{
Console.WriteLine("C# 3.0时代的事件处理方式");
Console.WriteLine(a + b);
};
program.AddEvent(x, y);
}
static void program_AddEvent(int a, int b)
{
Console.WriteLine("C# 1.0时代的事件处理方式");
Console.WriteLine( a + b );
}
}
}
