方法一：（将事件放在窗体上可以，但是窗体上如果放了pannel或其它控件将此事件放在控件上就不行了）
         private Point mPoint = new Point();

         private void Form1_MouseDown(object sender, MouseEventArgs e)
         {
             mPoint.X = e.X;
             mPoint.Y = e.Y;
         }

         private void Form1_MouseMove(object sender, MouseEventArgs e)
         {
             if (e.Button == MouseButtons.Left)
             {
                 Point myPosittion = MousePosition;
                 myPosittion.Offset(-mPoint.X, -mPoint.Y);
                 Location = myPosittion;
             }
         }

方法二：上述情况都可以

[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]
public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
ReleaseCapture(); //释放鼠标捕捉
//发送左键点击的消息至该窗体(标题栏)
SendMessage(Handle, 0xA1, 0x02, 0);
}
}
