怎么么取得线程的返回值啊。。。是不是用callback啊 100分相送

Question

Answer 1

线程没有返回值，参见MSDN。
使用全局变量，等方法传递数据。

Answer 2

封装一下线程，这样即可以传任意的参数，也可以控制线程及取得返回值之类的
示例：
public MyThread
{
    public object ThreadParam = null;
    Thread workThread = null;
    object workThreadRet = nulll;
 
    public MyThread(){}
    public Start(){
         workThread = new Thread( new ThreadStart( proc ) );
         workThread.Start();
    }
    public void Abort(){
         if( workThread != null ) workThread.Abort();
    }
   
    void proc(){
        ...
        workThreadRet = ...;
    }
}

Answer 3

get string sRtnMsg
 {
   retrun  this.global
  }
