从 Selenium webdriver 的当前窗口 GUID 获取窗口句柄 (IntPtr)

我试图捕获整个浏览器屏幕（例如任何工具栏、面板等）的屏幕截图，而不仅仅是整个页面，所以我得到了以下代码：

using (FirefoxDriver driver = new FirefoxDriver())
{ 
    driver.Navigate().GoToUrl(url);                

    ScreenCapture sc = new ScreenCapture();

    // How can I find natural IntPtr handle of window here, using GUID-like identifier returning by driver.currentWindowHandle?
    Image img = sc.CaptureWindow(...);
    MemoryStream ms = new MemoryStream();
    img.Save(ms, ImageFormat.Jpeg);
    return new FileStreamResult(ms, "image/jpeg");
}

您可以使用获取窗口句柄Process.GetProcesses:

using (FirefoxDriver driver = new FirefoxDriver())
{
    driver.Navigate().GoToUrl(url);

    string title = String.Format("{0} - Mozilla Firefox", driver.Title);
    var process = Process.GetProcesses()
        .FirstOrDefault(x => x.MainWindowTitle == title);

    if (process != null)
    {
        var screenCapture = new ScreenCapture();
        var image = screenCapture.CaptureWindow(process.MainWindowHandle);
        // ...
    }
}

当然，这假设您有一个具有该特定标题的浏览器实例。
