How to query string to a web site using get method?

Question

I want to send an information along with the url like a query string to the web site. This is exactly I call

Process.Start("http://domain.com?value=anything");

but I don't want to open browser because don't want to interrupt the user who is using the software.

I have googled for this but I found some HttpRequest code but the problem is this those program is not appending the query string. They are just returning me the html text of the web page.

I want to retrieve that information to store in database. Please guide me in this case.

Use WebClient.DownloadString to get a page from a specific url, without using browsers:

var x = WebClient.DownloadString("http://domain.com?value=anything");

So your question is: how to create a query string? – Patrick Hofman Sep 24 '14 at 12:26
Yes. Can you assist me in this case? – RaviKant Hudda Sep 24 '14 at 12:27
Query strings are only parameters (although you can supply them with a POST). I never read he wants a POST. – Patrick Hofman Sep 24 '14 at 14:38
So, this sends information, right? I think OP should clarify. – Patrick Hofman Sep 24 '14 at 14:39
The use of `HttpClient` is overkill here. `DownloadString` does a GET too. – Patrick Hofman Sep 24 '14 at 14:43
@user3756000: I would be glad to help but you need to explain yourself better. – Patrick Hofman Sep 24 '14 at 15:03
My clarification about the problem is this I want to use web service kind of facility where I can provide the web developer some information from my desktop application via query string but in hidden form. As I have mentioned in my above given problem that I want to transfer information in hidden form. – RaviKant Hudda Sep 25 '14 at 08:21

Here is something I use to perform a GET:

public T Get<T>(string url, IEnumerable<KeyValuePair<string, string>> data)
{
    var webApiUri = ConfigurationManager.AppSettings["WebApiUri"];

    var client = new HttpClient();

    try
    {
        string queryString = string.Empty;

        if (data != null)
        {
            queryString = data.Distinct().Select(x => string.Format("{0}={1}", x.Key, x.Value)).ToDelimitedString("&");
        }

        var response = client.GetAsync(string.Format("{0}/{1}?{2}", webApiUri, url, queryString)).Result;
        var responseContent = response.Content.ReadAsStringAsync().Result;
        return JsonConvert.DeserializeObject<T>(responseContent);
    }
    catch (Exception ex)
    {
        Debug.Assert(false, ex.Message);
        throw;
    }
}

T is the return type of the method. The response is expected as JSON, but you don't have to worry about that part. It's how the client performs a GET request that you're interested in. This is just example based around a JSON result.

See edits. Its just an example of how to perform a GET request to website with some information. I'm trying to help the OP and this is what I understand him to be asking. — Callum Linington, Sep 24 '14 at 14:46
