在PhantomJS C#中设置屏幕大小由Selenium驱动

如何设置浏览器屏幕大小？当我在如下设置PhantomJS后进行屏幕截图时，它只显示一个400px宽的图像

var driverService = PhantomJSDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;
driverService.LoadImages = false;
driverService.ProxyType = "none";      

using (var driver = new PhantomJSDriver(driverService))
{
    etc....
}

它应该与在任何其他浏览器中设置窗口大小相同，请随意查看以下示例：

下面是为我测试的代码：

var driverService = PhantomJSDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;
driverService.LoadImages = false;
driverService.ProxyType = "none";

using (var driver = new PhantomJSDriver(driverService)) {
    driver.Manage().Window.Size = new Size(1920, 1080); // Size is a type in assembly "System.Drawing"
    driver.Url = "http://www.stackoverflow.com";
    driver.TakeScreenshot().SaveAsFile(@"c:\phantomjs_screenshot.png", ImageFormat.Png);
}

TakeScreenshot

方法在更高版本中已更改为

GetScreenshot
