ASP.NET 定时器回调方法
代码：
using System;
using System.Collections.Generic;
using System.Text;
namespace NET.MST.Sixth.Reenter
{
class Reenter
{
//用来造成线程同步问题的静态成员
private static int TestInt1=0;
private static int TestInt2 = 0;
private static object locko = new object();
static void Main(string[] args)
{
Console.WriteLine("System.Timers.Timer 回调方法重入测试：");
TimersTimerReenter();
//这里确保已经开始的回调方法有机会结束
System.Threading.Thread.Sleep(2 * 1000);
Console.WriteLine("System.Threading.Timer 回调方法重入测试：");
ThreadingTimerReenter();
Console.Read();
}
