I got a response on a url
Once I read the response i get this string as below

id=657ec95c439eb4a76e48c5ea7&amount=1&notify_status=success&currency=USD&time=20190403095815&reference=190403175800PTM03428&notify_id=D0000036639-a6d98e5d0a08d3e8850f&fields=id%2Camount%2Cnotify_status%2Ccurrency%2Ctime%2Creference%2Cnotify_id&sign=997b961b0541fb64b4c31096bc059055

I need to short this string like below
amount=1&currency=USD& fields=id%2Camount%2Cnotify_status%2Ccurrency%2Ctime%2Creference%2Cnotify_id&id=657ec95c439eb4a76e48c5ea7&notify_id=D0000036639-a6d98e5d0a08d3e8850f &notify_status=success&reference=190403175800PTM03428&sign=997b961b0541fb64b4c31096bc059055&time=20190403095815

Basically, I need short by keys and my string is like key1=value1&key2=value2&key3=value3

Appreciate any Help

What I have tried:

string   requestJson = "id=657ec95c439eb4a76e48c5ea7&amount=1&notify_status=success&currency=USD&time=20190403095815&reference=190403175800PTM03428&notify_id=D0000036639-a6d98e5d0a08d3e8850f&fields=id%2Camount%2Cnotify_status%2Ccurrency%2Ctime%2Creference%2Cnotify_id&sign=997b961b0541fb64b4c31096bc059055";

            var list = new JavaScriptSerializer().Deserialize<Dictionary<string, string>>(requestJson);



            SortedDictionary<string, string> parameters = new SortedDictionary<string, string>();
            foreach (var term in list)
            {
                if (term.Key == "sign")
                    continue;

                parameters.Add(term.Key, term.Value);
            }

Why?

Keith Barrow 4-Apr-19 5:30am

The JavaScriptSerializer.Deserialize method isn't going to deserialize the query parameters - it is expecting a JSON string. OriginalGriff's solution is where I'd start.

Also Mehdi Gholam asks a good question - I can't think of a good reason why you'd want to do this other than as an exercise. That doesn't mean there isn't a good reason, but its good to question "am I actually solving the correct problem".

Take your string, and use Split, then sort the array:

string query = @"id = 657ec95c439eb4a76e48c5ea7 & amount = 1 & notify_status = success & currency = USD & time = 20190403095815 & reference = 190403175800PTM03428 & notify_id = D0000036639 - a6d98e5d0a08d3e8850f & fields = id % 2Camount % 2Cnotify_status % 2Ccurrency % 2Ctime % 2Creference % 2Cnotify_id & sign = 997b961b0541fb64b4c31096bc059055";
string trimmed = query.Replace(" & ", "&");
string[] queries = trimmed.Split('&');
queries = queries.Select(q => q.Trim()).OrderBy(q => q).ToArray();

If it wasn't for the spaces around the '&' in your original string (which I think are probably spurious) you could just use Array.Sort:

string query = @"id = 657ec95c439eb4a76e48c5ea7 & amount = 1 & notify_status = success & currency = USD & time = 20190403095815 & reference = 190403175800PTM03428 & notify_id = D0000036639 - a6d98e5d0a08d3e8850f & fields = id % 2Camount % 2Cnotify_status % 2Ccurrency % 2Ctime % 2Creference % 2Cnotify_id & sign = 997b961b0541fb64b4c31096bc059055";
string[] queries = query.Split('&');
Array.Sort(queries);
