Simulating a Mouse Double-Click is not working

Question

I am working on my project in Windows Form and need to simulate a Mouse Click. I get coordinates from textbox and after pressing button it must make Double Click but unfortunately I it isn't making Click. Can anyone say the reason ? Here is a code :

[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern void mouse_event(uint dwFlags, int dx, int dy, int dwData, int dwExtraInfo);

        private const int MOUSEEVENT_LEFTDOWN = 0x0002;
        private const int MOUSEEVENTF_LEFTUP = 0x0004;
        private const int MOUSEEVENTF_RIGHTDOWN = 0x0008;
        private const int MOUSEEVENTF_RIGHTUP = 0x0010;
        private const int MOUSEEVENTF_ABSOLUTE = 0x8000;

        private void button2_Click(object sender, EventArgs e)
        {
            int x = Convert.ToInt32(textBox1.Text);
            int y = Convert.ToInt32(textBox2.Text);
                mouse_event(MOUSEEVENT_LEFTDOWN, x, y, 0, 0);
                mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0);
                mouse_event(MOUSEEVENT_LEFTDOWN, x, y, 0, 0);
                mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0);

        }

btw, [``mouse_event``](https://msdn.microsoft.com/de-de/library/windows/desktop/ms646260(v=vs.85).aspx) isn't supported anymore, use [``SendInput``](https://msdn.microsoft.com/de-de/library/windows/desktop/ms646310(v=vs.85).aspx) instead. — Binkan Salaryman, Sep 17 '15 at 14:46

Based on This MSDN discussion you might have to wait between the clicks.

[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(uint dwFlags, int dx, int dy, int dwData, int dwExtraInfo);

private const int MOUSEEVENT_LEFTDOWN = 0x0002;
private const int MOUSEEVENTF_LEFTUP = 0x0004;
private const int MOUSEEVENTF_RIGHTDOWN = 0x0008;
private const int MOUSEEVENTF_RIGHTUP = 0x0010;
private const int MOUSEEVENTF_ABSOLUTE = 0x8000;

private void button2_Click(object sender, EventArgs e)
{
    int x = Convert.ToInt32(textBox1.Text);
    int y = Convert.ToInt32(textBox2.Text);
    mouse_event(MOUSEEVENT_LEFTDOWN, x, y, 0, 0);
    mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0);
    Thread.Sleep(50);
    mouse_event(MOUSEEVENT_LEFTDOWN, x, y, 0, 0);
    mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0);
}
