從VS2005開始就不允許非創(chuàng)建此控件的線程來(lái)調(diào)用它，那么解決方法是在該控件所在窗體里加上一句話：
CheckForIllegalCrossThreadCalls = false;

        private void Form1_Load(object sender, EventArgs e)
        {
            CheckForIllegalCrossThreadCalls = false;
            //信號(hào)量
            signel sgl = new signel(10);

            //新建一個(gè)隊(duì)列緩沖區(qū)
            Queue<int> que = new Queue<int>(10);
            Reader readerThread = new Reader(sgl,que,this);
            Writer writerThread = new Writer(sgl,que,this);
            //開啟兩個(gè)線程
            Thread tRead = new Thread(readerThread.Process);
            Thread tWrite= new Thread(writerThread.Process);
            tRead.Start();
            tWrite.Start();
        }
