鼠标点击chrome从c#应用程序

我正在尝试构建一个简单的应用程序，它所做的就是点击Chrome浏览器中的特定位置。

我从代码

开始这个过程

var proc = Process.Start("chrome.exe",
"https://www.youtube.com/results?search_query=" + textBox1.Text);

现在我想用鼠标点击它

这是我尝试过的

    private void buttonGO_Click(object sender, EventArgs e)
    {
        IntPtr iHandle = FindWindow(null, "Chrome");
        if (iHandle != IntPtr.Zero)
        {
            SetForegroundWindow(iHandle);
            Thread.Sleep(2000);
            moveToPos(30000, 19500);
            Thread.Sleep(500);
            performClick(30000, 19500);
        }
    }
    private void performClick(uint x, uint y)
    {
        SetCursorPos(x, y);
        mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN, x, y, 0, UIntPtr.Zero);
        Thread.Sleep(200);
        mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTUP, x, y, 0, UIntPtr.Zero);
    }
    private void moveToPos(uint x, uint y)
    {
        mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE, x, y, 0, UIntPtr.Zero);
    }

但是它找不到窗户。有人知道吗?

private void buttonGO_Click(object sender, EventArgs e)
{
    // Get all chrome processes
    Process[] chromeProcesses = Process.GetProcessesByName("chrome");
    Process uiProcess = null;
    foreach (Process process in chromeProcesses)
    {
        // Assuming you've opened chrome only once, the UI process will have MainWindowHandle, so get its reference and break out of loop
        if (process.MainWindowHandle != IntPtr.Zero)
        {
            uiProcess = process;
            break;
        }
    }
    if (uiProcess == null)
        return;
    // Do your stuff here
    IntPtr iHandle = uiProcess.MainWindowHandle;
    if (iHandle != IntPtr.Zero)
    {
        SetForegroundWindow(iHandle);
        Thread.Sleep(2000);
        moveToPos(30000, 19500);
        Thread.Sleep(500);
        performClick(30000, 19500);
    }
}
