Get info from text string

I have a string like this:

var info = "status=ACCEPTED&code=12345&type=CARD&id=98765";

How can I in a simple way get info from this string?

Example: I only want to get the "status" value from the string, in this case "ACCEPTED".

In case you like less lines of code :)

var info = "status=ACCEPTED&code=12345&type=CARD&id=98765";
var getInfo = new Func<string, string>(x => info.Split('&').Select(y => y.Split('=')).Where(y => y.Length > 1 && y[0] == x).Select(y => y[1]).FirstOrDefault());

Now simply call it as -

var a = getInfo("status");
var b = getInfo("id");
var c = getInfo("something");

Result -

a = ACCEPTED

b = 98765

c = null

Concept is same, split by & then by =. I am using LINQ to get the result.

using Linq:

var info = "status=ACCEPTED&code=12345&type=CARD&id=98765";
var field = "status";
var value = info.Split('&').Select(i => i.Split('='))
   .Where(f => f[0].Equals(field)).Select(f => f[1]).FirstOrDefault();

First split by '&' then split by = and create dictionary out of it.

Below is a c# code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;

namespace Rextester
{
 public class Program
 {
    public static void Main(string[] args)
    {

        Program prog = new Program();
        Dictionary<String,String> output = prog.splitString("status=ACCEPTED&code=12345&type=CARD&id=98765");
        Console.WriteLine(output["status"]);

    }

    public Dictionary<string,string> splitString(string text) {
      Dictionary<string,string> output = new Dictionary<string,string>();
        if(text != null) {
            string[] keyValueArray = text.Split('&');
            foreach(string keyVal in keyValueArray) {
                string[] finalSplit = keyVal.Split('=');
                output.Add(finalSplit[0],finalSplit[1]);
            }
        }
        return output;
    }
  }
}

you can take advantage of Linq Split then convert it to List to be finalized into a Dictionary<string, string>.

You can also create a simple model to convert it to object.

this is a simple helper method will do what you need : 

public IDictionary<string, string> GetInfo(string info)
{
    var infoDic = new Dictionary<string, string>();

    var str = info.Split('&').ToList();

    for (int x = 0; x < str.Count; x++)
    {
        var pair = str[x].Split('=');

        infoDic.Add(pair[0], pair[1]);
    }

    return infoDic;

}

usage : 

var info = "status=ACCEPTED&code=12345&type=CARD&id=98765";

var result = GetInfo(info);

var status = result.Where(x => x.Key.ToLower() == "status")
            .Select(x => x.Value)
            .First()
            .ToString();

Use the HttpUtility.ParseQueryString() method like this:

var parsed = HttpUtility.ParseQueryString(info);

// now you can use parsed["status"], parsed["code"], parsed["type"], and parsed["id"], which will all be strings
