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.

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}&arg2={1}", Uri.EscapeDataString("escape me"), Uri.EscapeDataString("& me !!")); string text; using (WebClient client = new WebClient()) { text = client.DownloadString(address); }

In a GET request, you pass parameters as part of the query string.
string url = "http://somesite.com?var=12345";

If you enter the complete url including the parameters in the adresse bar of iexplore, do I then get the same response as is make a http request get from c#

Updated. The other answer is more complete anyway.
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 > 0) { foreach (string header in RequestHeaders.AllKeys) client.Headers.Add(header, RequestHeaders[header]); } } if (QueryStringParameters != null) { if (QueryStringParameters.Count > 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");

GET request with multiple params:
curl --request GET --url http://localhost:8080/todos/?limit=10&offset=2 --header 'content-type:application/json'

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
