最简单的.NET事件调用 方法

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace EventDemo
{
class Program
{
static void Main(string[] args)
{
//如何使用事件
SumCount sum = new SumCount();
//调用方法
sum.outputEvent += new SumCount.OutputValue(outPut);
sum.Begin();
Console.Read();
}
public static void outPut(int i)
{
Console.WriteLine("输入：{0}", i);
}
}

class SumCount
{
//封装
public delegate void OutputValue(int i);
public event OutputValue outputEvent;
public void Begin()
{
for (int i = 0; i < 100; i++)
{
if (i % 2 == 0)
{
outputEvent(i);
}
}
}
}
}
