[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]
public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
public const int WM_SYSCOMMAND = 0x0112;
public const int SC_MOVE = 0xF010;
public const int HTCAPTION = 0x0002;
在窗体的mousedown事件中实现拖动。
private void frmWinCalendar_MouseDown(object sender, MouseEventArgs e)
{
//拖动窗体
this.Cursor = System.Windows.Forms.Cursors.Hand; //改变鼠标样式
ReleaseCapture();
SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
this.Cursor = System.Windows.Forms.Cursors.Default;
}
