public static void Main()

{

string str ="RESULT=0&PNREF=A10AABBF8DF2&RESPMSG=Approved&AUTHCODE=668PNI&PREFPSMSG=No Rules Triggered&POSTFPSMSG=No Rules Triggered";

    var sr = str.Replace("&", "=");

    string[] sp = sr.Split('=');

    var spl = sp.Length;

    int n = 1;

    var ss = "{";

    for (var k = 0; k < spl; k++)
    {
        if (n % 2 == 0)
        {
            if (n == spl)
            {
                ss += '"' + sp[k] + '"';
            }
            else
            {
                ss += '"' + sp[k] + '"' + ",";
            }
        }
        else
        {
            ss += '"' + sp[k] + '"' + ":";
        }
        n++;
    }
    ss += "}";
    Console.WriteLine(ss);
