C#控制台计时器问题

[lchh0917]

using System;
using System.Collections.Generic;
using System.Text;
using System.Timers;

namespace Ch13Ex01
{
    class Program
    {
        static int counter = 0;
        static string displayString =
            "This string will appear one letter at a time."+"Let begones be begones,don't drewll on the past too much."
            +"Game is over,just I want to deal with it perfectly";

        static void Main(string[] args)
        {
            Console.WriteLine("Game Start:  Press any key to continue...");
            Timer myTimer = new Timer(100);
            myTimer.Elapsed += new ElapsedEventHandler(WriteChar);
            myTimer.Start();
            Console.ReadKey();
        }

        static void WriteChar(object sender, ElapsedEventArgs e)
        {
            Console.Write(displayString[counter++ % displayString.Length]);
        }
    }
}

这个小小小程序实现将指定的字符串逐个字符间隔输出，但问题是它总在循环输出，怎么样使它只输出整个字符串偶only once，只要一次，如果可以的话再拓展下下，怎么通过键盘控制它在输出过程中暂停和继续
高手帮忙！

class Program
{
static int counter = 0;
static string displayString =
"This string will appear one letter at a time."+"Let begones be begones,don't drewll on the past too much."
+"Game is over,just I want to deal with it perfectly";

static void Main(string[] args)
{
Console.WriteLine("Game Start: Press any key to continue...");
Timer myTimer = new Timer(100);
myTimer.Elapsed += new ElapsedEventHandler(WriteChar);
myTimer.Start();
Console.ReadKey()counter = 0;
}

static void WriteChar(object sender, ElapsedEventArgs e)
{
if(counter == 0 )
{
Console.Write(displayString[counter++ % displayString.Length]);
counter++;
}
}
}
}


如果要动态暂停开始的话再开一个线程监控键盘

2楼说的再开线程控制键盘，就是暂停和继续输入操作，具体怎么弄呀，我真的不会，烦大家帮忙啊！！！

            "Let begones be begones,don't drewll on the past too much." +

        }

        static void WriteChar(object sender, ElapsedEventArgs e)
        {
            int i = System.Threading.Interlocked.Increment(ref counter);
            if (i < displayString.Length)
            {
                Console.Write(displayString[i]);
            }
        }
    }
}

3楼代码我用过了，恩，暂停可以通过，但就是暂停后不能再继续输出了。。。
还是那个继续的代码段通不过啊好像，大家帮忙 啊，嘿嘿！

[foutcast]

namespace Ch13Ex01
{
class Program
{
static int counter = 0;
static string displayString =
"This string will appear one letter at a time."+"Let begones be begones,don't drewll on the past too much."
+"Game is over,just I want to deal with it perfectly";

static void Main(string[] args)
{
Console.WriteLine("Game Start: Press any key to continue...");
Timer myTimer = new Timer(100);
myTimer.Elapsed += new ElapsedEventHandler(WriteChar);
myTimer.Start();
_thread1 = new Thread(new ThreadStart(Listen));
_thread1.Start();//启动监听线程
Console.ReadKey();
}

static void WriteChar(object sender, ElapsedEventArgs e)
{
if(counter == 0 ) //
{
Console.Write(displayString[counter++ % displayString.Length]);
counter++; //如果显示玩一行，不再显示
}
}

public Listen()
{
while (true)
{
switch (Console.ReadKey().Key)
{
case ConsoleKey.Spacebar:
Console.CursorLeft--;
myTimer.Enabled = !myTimer.Enabled;
break;
case ConsoleKey.Enter:
Console.WriteLine();
System.Threading.Interlocked.Exchange(ref counter, 0);
break;
default:
return;
}
}
}
}
}


Listen这段我是直接拿上面的，用来
