سلام
اینطوری عمل کنید :
[DllImport("user32")]
private static extern int SetCursorPos(int x, int y);
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
private static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);
private const int MOUSEEVENTF_MOVE = 0x0001; /* mouse move */
private const int MOUSEEVENTF_LEFTDOWN = 0x0002; /* left button down */
private const int MOUSEEVENTF_LEFTUP = 0x0004; /* left button up */
private const int MOUSEEVENTF_RIGHTDOWN = 0x0008; /* right button down */
public static void Click(int X, int Y)
{
SetCursorPos(X, Y);
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
}
