WPF禁用窗口移动

Question

在wpf我如何防止用户通过拖动标题栏来移动窗口？

既然你不能在WPF直接定义WndProc，你需要获得HwndSource，并添加一个钩到它：

public Window1() 
{ 
    InitializeComponent(); 

    this.SourceInitialized += Window1_SourceInitialized; 
} 

private void Window1_SourceInitialized(object sender, EventArgs e) 
{ 
    WindowInteropHelper helper = new WindowInteropHelper(this); 
    HwndSource source = HwndSource.FromHwnd(helper.Handle); 
    source.AddHook(WndProc);  
} 

const int WM_SYSCOMMAND = 0x0112; 
const int SC_MOVE = 0xF010; 

private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled) 
{ 

    switch(msg) 
    { 
     case WM_SYSCOMMAND: 
      int command = wParam.ToInt32() & 0xfff0; 
      if (command == SC_MOVE) 
      { 
      handled = true; 
      } 
      break; 
     default: 
      break; 
    } 
    return IntPtr.Zero; 
}
