[DllImport("user32.dll", EntryPoint = "ReleaseCapture")]public static extern void ReleaseCapture();[DllImport("user32.dll", EntryPoint = "SendMessage")]public static extern void SendMessage(int hwnd, int wMsg, int wParam, int lParam);把上面语句加载窗体类文件中，然后在拖拽的控件上加事件，比如我是一个panel
private void panelForm_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { ReleaseCapture(); SendMessage((int)移动的对象.Handle, 0xA1, 2, 0); //是窗体自身就是 //SendMessage((int)this.Handle, 0xA1, 2, 0); //panel就是SendMessage((int)panel1.Handle, 0xA1, 2, 0); } } |
这种才是windows标准的拖拽事件，下面那位，拖动的时候窗体会闪烁不停，一直在渲染背景
