The solutions is to set the default proxy for the web request and assign user agent to it as shown below: ListURL = String.Format( "your_xml_feed_or_API_url_sample" ); HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(ListURL); request.Timeout = 900000000; request.Proxy = HttpWebRequest.DefaultWebProxy; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)" ; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream dataStream = response.GetResponseStream(); dataStream = response.GetResponseStream(); StreamReader reader = new StreamReader(dataStream); ListingSource = reader.ReadToEnd(); ListingSource = System.Web.HttpUtility.HtmlDecode(ListingSource); Cheers!

Invalid Expanded Name In LINQ to XML

-
Assuming I am reading this xml file using XLINQ. I encountered an error that says invalid expanded name. As i go through this xml file, i found a node images that contains element tags. The parent node is also an element tag. Since i don't use the images tag, I simply remove it using string manipulations. Below is the xml file and the solution: <element> <id> 2768687195 </id> <title> Customer Service Representative </title> <body> Do you dream of being your own boss and choosing the work you do, when you work and who you work for? </body> <url> http://jobs.myjob.careercenter-servicecrew.html </url> <category> <id> job/customer_service </id> <name> Customer Service &amp; Call Center Jobs </name> </category> <source> <id> www </id>

Uncompress GZip Response Using WebClient In C#

-
In a scenario where you want to download xml data using webclient, the response from firefox or any browser will display the xml file correctly. However, using a web request/webclient.downloadstring to download the xml file, the response is somewhat corrupted or in hashed form. The response headers are the following: 1. Content-Type - application/xml 2. Content-Encoding - gzip As you can see, the content encoding is of type gzip . The solution is to override the web request method to something like this: class DecompressGzipResponse : WebClient { protected override WebRequest GetWebRequest (Uri address) { HttpWebRequest request = (HttpWebRequest) base .GetWebRequest(address); request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate; return request; } } //to use this in the program (main function) DecompressGzipResponse client = new DecompressGzipResponse (); Listi
