类的成员怎么能够使用类本身呢？
1、http://www.cnblogs.com/danielWise/archive/2012/02/10/2346117.html

 private void SetText(string text)
        {           
            if (this.textBox1.InvokeRequired)
            {   
                SetTextCallback d = new SetTextCallback(SetText);
                this.Invoke(d, new object[] { text });
            }
            else
            {
                this.textBox1.Text = text;
            }
        }

 class NETMutex
    {
        static Mutex myMutex;
        public static void Main()
        {
            myMutex = new Mutex(true, "WROX");
            NETMutex nm = new NETMutex();
            Thread t = new Thread(new ThreadStart(nm.Run));
            t.Start();
            Console.WriteLine("Thread Sleep for 5 sec");
            Thread.Sleep(5000);
            Console.WriteLine("Thread Woke Up");
            myMutex.ReleaseMutex();
            Console.WriteLine("Before WaitOne");
            myMutex.WaitOne();
            Console.WriteLine("Lock owned by Main Thread");
            Console.ReadLine();
        }

经验证，第一个示例是一个死循环。进行以下改造后测试通过！

 private void SetText(string text)
{           
      if (this.textBox1.InvokeRequired)
      {   
           SetTextCallback d = new SetTextCallback(UpdateResult);
           this.Invoke(d, new object[] { text });
       }
       else
      {
           UpdateResult(text);
                    //this.textBox1.Text = text;//直接这样也可以
      }
}

private void UpdateResult(string text)
{
            this.textBox1.Text = text;
}

虽然问题解决了，但感觉这样的逻辑好啰嗦的有木有？
