如果你觉得字符串读取写入确实需要用线程的地步那就必须加锁，否则会有脏数据。

private static StringBuilder strs = new StringBuilder();
        private static BackgroundWorker backgroundWorker;

        static void Main(string[] args)
        {
            backgroundWorker = new BackgroundWorker();
            backgroundWorker.DoWork += TransString;
            backgroundWorker.RunWorkerCompleted += DisplayString;

            //处理string
            for (int i = 0; i < 10; i++)
            {
                string str = Console.ReadLine();
                backgroundWorker.RunWorkerAsync(Tuple.Create(strs.ToString(), str));
                strs.Append(str);
            }

            Console.ReadLine(); 
        }

        /// <summary>
        /// 传递string
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private static void TransString(object sender,DoWorkEventArgs e)
        {
            var t = e.Argument as Tuple<string,string>;

            e.Result = t.Item1 + t.Item2;
        }

        /// <summary>
        /// 显示string
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private static void DisplayString(object sender, RunWorkerCompletedEventArgs e)
        {
            Console.WriteLine(e.Result.ToString());
        }

只要一个

backgroundworker

就可搞定！

用StringBuilder如果不加锁你没办法保证操作时的线程安全,而如果加锁的话和你希望同步处理的初衷又违背了,所以不要用stringbuilder, 附上使用Queue的方法


	public class StringQueueTest
	{
		private int cnt=0;
		private Queue<string> strings=new Queue<string>();
		
		public StringQueueTest()
		{
			Thread thread1=new Thread(new ThreadStart(Start1));
			Thread thread2=new Thread(new ThreadStart(Start2));
			thread1.Start();
			thread2.Start();
		}

		
		private void Start1()
		{
			while (true) 
			{
				string s=(cnt++).ToString();
				Console.WriteLine(s);
				strings.Enqueue(s);
				Thread.Sleep(1000);
			}
		}
		
		private void Start2()
		{
			while (true) 
			{
				while (strings.Count>0) 
				{
					Console.WriteLine(strings.Dequeue());
				}
				Thread.Sleep(100);
			}
		}
	}
