我是C#的初学者。当我使用win.forms时,线程出现问题。我的应用程序冻结。这个代码有什么问题?我正在使用msdn的微软示例。 这里是我的代码:C#中的多线程与Win.Forms控件
delegate void SetTextCallback(object text);
private void WriteString(object text)
{
// InvokeRequired required compares the thread ID of the
// calling thread to the thread ID of the creating thread.
// If these threads are different, it returns true.
if (this.textBox1.InvokeRequired)
{
SetTextCallback d = new SetTextCallback(WriteString);
this.Invoke(d, new object[] { text });
}
else
{
for (int i = 0; i <= 1000; i++)
{
this.textBox1.Text = text.ToString();
}
}
}
private void button1_Click(object sender, EventArgs e)
{
Thread th_1 = new Thread(WriteString);
Thread th_2 = new Thread(WriteString);
Thread th_3 = new Thread(WriteString);
Thread th_4 = new Thread(WriteString);
th_1.Priority = ThreadPriority.Highest; // самый высокий
th_2.Priority = ThreadPriority.BelowNormal; // выше среднего
th_3.Priority = ThreadPriority.Normal; // средний
th_4.Priority = ThreadPriority.Lowest; // низкий
th_1.Start("1");
th_2.Start("2");
th_3.Start("3");
th_4.Start("4");
th_1.Join();
th_2.Join();
th_3.Join();
th_4.Join();
}
也不例外,我的表单刚刚冻结 – 2013-03-22 19:42:33
您是否尝试调试应用程序以查看它正在被挂起的位置? – 2013-03-22 19:42:53
嗯,很高兴知道!它什么时候冻结? – 2013-03-22 19:42:55
