推荐答案
此方式将这些问题遭受如果使用加载HTML WebBrowser.NavigateToString 或隔离相对链接的图像存储无，脚本或CSS会工作。此外，它不可能从的HttpWebRequest 任何cookie传递给 web浏览器
This way will suffer from these problems as if you load the HTML using WebBrowser.NavigateToString or from Isolated Storage none of the relative links to images, scripts or CSS will work. Also it is impossible to pass any Cookies from HttpWebRequest to the WebBrowser
要做到这一点的方法是使用的 WebBrowser控件本身做POST。还有就是 WebBrowser.Navigate 方法的。这将允许你POST数据到您的网址。
The way to do this is to use the WebBrowser control itself to do the POST. There is a overload of the WebBrowser.Navigate method as documented on MSDN here. That will allow you to POST data to your URL.
// generate your form data based on the data you got from your "portrait page"
// and get the bytes from that.
// (e.g. write your post data to a MemoryStream as UTF8 and get its bytes)
byte[] formBytes = ...
// write HTTP headers here, including the type of data you're posting, e.g.:
string headers = "Content-Type: application/x-www-form-urlencoded"
+ Environment.NewLine;
Uri uri = ... // where you want the POST data to be sent
this.webBrowser.Navigate(uri, formBytes, headers);
这样，你的Web浏览器将进行正确的初始化和你的Cookie，图片，脚本和CSS都应该工作。
That way your web browser will be properly initialized and your cookies, images, scripts and CSS should all work.
