compose a query URL string

Question

I am searching for a construction to build a method in (C#) for construct a query URL based on Dictionary list. The solution I build didn't matched with the output I want. Does someone I better idea?

public string querystring()
{
    //start with ? 
    var startPosition = string.Join("?", availiblebalance.FirstOrDefault().Key + "=" + availiblebalance.FirstOrDefault().Value);
    //var removeElement = startPosition.Split('='); availiblebalance.Remove(removeElement[0]); 
    var otherPostions = string.Join("&", availiblebalance.Select(x => x.Key + "=" + x.Value).ToArray());

    var result = string.Format("{0}{1}", startPosition,otherPostions);
    return result;
}

The solution I build didn't matched with the output I want - you might want to tell us what you do want! — Jamiec

Is this answer of any use? stackoverflow.com/questions/829080/… Or maybe this article java2s.com/Code/CSharp/Network/DictionaryToQueryString.htm — user755404

Building a query string from a dictionary should be fairly straightforward - you dont need to treat the start position and the rest of the params separately.

var queryString = "?" + String.Join("&", 
          myDictionary.Select(kv => String.Concat(kv.Key,"=",kv.Value)));

You may need to UrlEncode the values, depending on what they contain.

There is an HttpUtility that allows you to build the query string.

var queryString = System.Web.HttpUtility.ParseQueryString(string.Empty);
foreach (var entry in myDictionary)
    queryString[entry.Key] = entry.Value;

return "?" + queryString.ToString();
