我使用以下方法截取屏幕截图，并注意到所有屏幕截图图像都没有捕获整个窗口，而是裁剪窗口。例如，我将获得一个.jpg，我无法看到屏幕上可见的整个网页。我怀疑当DOM中不可见某些元素并因此未包含在屏幕截图中时会发生这种情况。这是预期的行为吗？如果这是预期的，有没有办法编程驱动程序一致地使用Selenium 32位Internet Explorer驱动程序进行全屏捕获？这是我打电话截取屏幕截图的方法。
public static void TakeScreenshot(IWebDriver driver, string saveLocation)
{
ITakesScreenshot ssdriver = driver as ITakesScreenshot;
Screenshot screenshot = ssdriver.GetScreenshot();
screenshot.SaveAsFile(saveLocation, ImageFormat.png);
}

这是我用来捕捉整个屏幕的内容：
Rectangle bounds = Screen.GetBounds(Point.Empty);
using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using (Graphics g = Graphics.FromImage(bitmap))
{
g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
}
bitmap.Save(saveLocation, System.Drawing.Imaging.ImageFormat.Png);
}

为整页截图设置代码：

using System.Threading;
using OpenQA.Selenium;
using DotRez.Utilities.WebDriver;

事实上，理查德的答案将能够截取整个当前桌面区域的截图 - 如果这就是您所追求的，那么它将起作用。如果你实际上是在拥有一个没有最大化的特定应用程序（例如Internet Explorer）之后。使用Selenium时，您可能需要采用不同的方法。考虑强制应用程序最大化，甚至可以在使用上面的理查德方法拍摄屏幕截图之前获得焦点 - 或者使用Selenium的ITakesScreenshot界面......
