WPF 主窗口弹出新窗口线程问题……

[scutchjian]

这是我在网上找到的方法……
private void MenuItem_Click_13(object sender, RoutedEventArgs e)
{


this.WindowState = WindowState.Minimized;
Thread newWindowThread = new Thread(new ThreadStart(ThreadStartingPoint));
newWindowThread.SetApartmentState(ApartmentState.STA);
newWindowThread.IsBackground = true;
newWindowThread.Start();
}


private void ThreadStartingPoint()
{
screenpaint = new Screen_paint();//新的窗口
screenpaint.Show(); //一调试到这一句，整个程序就死掉，还黑屏……
System.Windows.Threading.Dispatcher.Run();
}
求大神指导……

WPF默认2个线程 一个用于UI绘制，响应用户输入执行后台代码 为什么把打开一个窗口放到你的线程里面去？ 你的线程应该仅仅处理数据

[那一份抹不去的光辉]

private void ThreadStartingPoint() { Action act = () => { screenpaint = new Screen_paint(); screenpaint.Show(); }; this.Dispatcher.BeginInvoke( DispatcherPriority.Normal, act); }
