        private const int WM_NCHITTEST = 0x84;
       private const int HTCLIENT = 0x1;
       private const int HTCAPTION = 0x2;
       protected override void WndProc(ref Message m)
       {
           switch (m.Msg)
           {
               case WM_NCHITTEST:
                   base.WndProc(ref m);
                   if ((int)m.Result == HTCLIENT)
                       m.Result = (IntPtr)HTCAPTION;
                   return;
                   break;
           }
           base.WndProc(ref m);
       }

-_-b
是没标题栏不能移动吧……

按下面的方法，你想要在什么地方移动窗体都行:

C# code
private const int WM_NCLBUTTONDOWN = 0xA1; //消息:左键点击private const int HT_CAPTION = 0x2; //标题栏[System.Runtime.InteropServices.DllImport("user32.dll")]private static extern int SendMessage(System.IntPtr hWnd, int Msg, int wParam, int lParam); //发送消息[System.Runtime.InteropServices.DllImport("user32.dll")]private static extern bool ReleaseCapture();private void Form1_MouseDown(object sender, MouseEventArgs e){  if (e.Button == MouseButtons.Left)  {    ReleaseCapture(); //释放鼠标捕捉    SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0); //发送左键点击的消息至该窗体(标题栏)  }}
