模擬鼠標雙擊不起作用

Question

我正在Windows窗體上的項目上工作，需要模擬鼠標單擊。 我從文本框中獲取坐標，按下按鈕后它必須進行雙擊，但是不幸的是我沒有進行點擊。 誰能說出原因？ 這是一個代碼：

[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);

        }

基於此MSDN討論，您可能需要在兩次單擊之間等待。

[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);
}
