如下，新建一个C#控制台应用程序，且在main方法中新建两个线程，分别调用两个方法：

Question

method1(),method2(),method1()用于执行一个循环，值为1-1000000000,method2()用于监听键盘输入，当输入A-Z任意键时循环暂停，按空格键循环继续，按Esc循环退出，应用程序终止，现在method1()和method2()我已经完成了，剩下的就是线程调用的问题了，已经实现了按任意键停止，但是不能继续，求高手帮忙解答，最好给段简短的代码。

Answer 1

使用Thread的Suspend方法可以暂停一个线程,Resume继续,给你写个例子吧

using System;
using System.Collections.Generic;
using System.Text;
using System.Text.RegularExpressions;
using System.IO;
using System.Threading;

namespace ConsoleApplication1
{
class Program
{
static Thread th1;
static Thread th2;
static int value = 0;
static void Main(string[] args)
{
th1 = new Thread(new ThreadStart(Method1));
th2 = new Thread(new ThreadStart(Method2));
th1.Start();
th2.Start();
}
static void Method1()
{
for (int i = 0; i < 1000000000; i++)
{
value++;
}
Console.WriteLine("完成");
}
static void Method2()
{
while (true)
{
ConsoleKeyInfo read = Console.ReadKey();
if (char.IsLetter(read.KeyChar))
{
if (th1.ThreadState == ThreadState.Stopped)
{
Console.WriteLine("th1已停止,按Esc键退出");
continue;
}
th1.Suspend();
Console.WriteLine("th1已挂起,value为{0}", value);
}
else if (read.Key == ConsoleKey.Spacebar)
{
if (th1.ThreadState == ThreadState.Stopped)
{
Console.WriteLine("th1已停止,按Esc键退出");
continue;
}
else if (th1.ThreadState == ThreadState.Running)
{
Console.WriteLine("th1正在运行");
continue;
}
th1.Resume();
Console.WriteLine("th1继续运行");
}
else if (read.Key == ConsoleKey.Escape)
{
th1.Abort();
th2.Abort();
return;
}
}
}
}
}
