Geek Speak - Useful functions

  • 项目

I would like to share some useful functions for you to use.  This is part of an application that I will eventually share when I get it completed.  In my last post, I showed how to create a FlowDocument from HTML, well I put that code into a function.  The other function, takes a URL and takes the HTML and returns it as a string.

public static string ConvertUrlToHtmlText(string url) {

try {

   HttpWebRequest request = HttpWebRequest.Create(new Uri(url)) as HttpWebRequest;
   HttpWebResponse response = request.GetResponse() as HttpWebResponse;
   StreamReader reader = new StreamReader(response.GetResponseStream());
   string convertedText = reader.ReadToEnd();
   return convertedText; 
}
catch (WebException) {
   return null;
}
catch (Exception) {
return null; 
}

}

public static FlowDocument ConvertTextToFlowDocument(string text) {

try {
   string xaml = HTMLConverter.HtmlToXamlConverter.ConvertHtmlToXaml(text, true);
   return XamlReader.Load(new XmlTextReader(new StringReader(xaml))) as FlowDocument;
}
catch (Exception) {
   return null;

}

}
