UriBuilder in Xamarin Forms

In Xamarin Forms there is a native function called UriBuilder: it allow you to create a well-formed url. In my implementation, all parameters are in a Dictionary called parameters. Using Linq, I put in builder.Query only the parameters with a value.

UriBuilder builder = new UriBuilder(yourUrl);

Dictionary<string, string> parameters = 
                              new Dictionary<string, string>();
parameters.Add("reference", Reference);
parameters.Add("param1", Param1);

builder.Query = 
    string.Join("&", 
        parameters.Where(p => !string.IsNullOrWhiteSpace(p.Value))
                  .Select(p => string.Format("{0}={1}", 
                                      Uri.EscapeDataString(p.Key), 
                                      Uri.EscapeDataString(p.Value))));
return builder.ToString();

Happy coding!
