Assuming you wanted to do this synchronously  using the WebClient OpenRead      method and setting the timeout on the Stream that it returns will give you the desired result   using  var webClient   new WebClient    using  var stream   webClient OpenRead streamingUri          if  stream    null                   stream ReadTimeout   Timeout Infinite            using  var reader   new StreamReader stream  Encoding UTF8  false                              string line                 while   line   reader ReadLine       null                                       if  line    String Empty                                                Console WriteLine  Count  0    count                                               Console WriteLine line                                           Deriving from WebClient and overriding GetWebRequest      to set the timeout  Beniamin suggested  didn t work for me as  but this did

My answer comes from here  You can make a derived class  which will set the timeout property of the base WebRequest class   using System  using System Net   public class WebDownload   WebClient            lt summary gt          Time in milliseconds          lt  summary gt      public int Timeout   get  set         public WebDownload     this 60000           public WebDownload int timeout                this Timeout   timeout             protected override WebRequest GetWebRequest Uri address                var request   base GetWebRequest address           if  request    null                        request Timeout   this Timeout                    return request            and you can use it just like the base WebClient class
