How to make an HTTP get request with parameters

Question

Is it possible to pass parameters with an HTTP get request  If so  how should I then do it  I have found an HTTP post requst  link   In that example the string postData is sent to a webserver  I would like to do the same using get instead  Google found this example on HTTP get here  However no parameters are sent to the web server

You can also pass value directly via URL.

If you want to call method public static void calling(string name){....}

then you should call usingHttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create("http://localhost:****/Report/calling?name=Priya); webrequest.Method = "GET"; webrequest.ContentType = "application/text";

Just make sure you are using ?Object = value in URL

In a GET request  you pass parameters as part of the query string   string url    http   somesite com var 12345

The WebRequest object seems like too much work for me  I prefer to use the WebClient control     To use this function you just need to create two NameValueCollections holding your parameters and request headers    Consider the following function       private static string DoGET string URL NameValueCollection QueryStringParameters   null  NameValueCollection RequestHeaders   null                string ResponseText   null          using  WebClient client   new WebClient                          try                               if  RequestHeaders    null                                        if  RequestHeaders Count  gt  0                                                foreach  string header in RequestHeaders AllKeys                              client Headers Add header  RequestHeaders header                                                            if  QueryStringParameters    null                                        if  QueryStringParameters Count  gt  0                                                foreach  string parm in QueryStringParameters AllKeys                              client QueryString Add parm  QueryStringParameters parm                                                            byte   ResponseBytes   client DownloadData URL                   ResponseText   Encoding UTF8 GetString ResponseBytes                             catch  WebException exception                                if  exception Response    null                                        var responseStream   exception Response GetResponseStream                         if  responseStream    null                                                using  var reader   new StreamReader responseStream                                                         Response Write reader ReadToEnd                                                                                                       return ResponseText          Add your querystring parameters  if required  as a NameValueCollection like so           NameValueCollection QueryStringParameters   new NameValueCollection            QueryStringParameters Add  id    123            QueryStringParameters Add  category    A      Add your http headers  if required  as a NameValueCollection like so           NameValueCollection RequestHttpHeaders   new NameValueCollection            RequestHttpHeaders Add  Authorization    Basic bGF3c2912XBANzg5ITppc2ltCzEF

My preferred way is this  It handles the escaping and parsing for you   WebClient webClient   new WebClient    webClient QueryString Add  param1    value1    webClient QueryString Add  param2    value2    string result   webClient DownloadString  http   theurl com

First WebClient is easier to use  GET arguments are specified on the query-string - the only trick is to remember to escape any values           string address   string Format               http   foobar somepage arg1  0  amp arg2  1                Uri EscapeDataString  escape me                Uri EscapeDataString   amp  me                string text          using  WebClient client   new WebClient                          text   client DownloadString address
