Comparing two Json objects in C#
String JsonDifferenceReport(String objectName,
                            JsonObject first,
                            JsonObject second)
{
  if(String.IsNullOrEmpty(objectName))
    throw new ArgumentNullException("objectName");
  if(null==first)
    throw new ArgumentNullException("first");
  if(null==second)
    throw new ArgumentNullException("second");
  List allKeys = new List();
  foreach(String key in first.Keys)
    if (!allKeys.Any(X => X.Equals(key))) allKeys.Add(key);
  foreach(String key in second.Keys)
    if (!allKeys.Any(X => X.Equals(key))) allKeys.Add(key);
  String results = String.Empty;
  foreach(String key in allKeys)
  {
    JsonValue v1 = first[key];
    JsonValue v1 = second[key];
    if (((null==v1) != (null==v2)) || !v1.Equals(v2))
    {
      if(String.IsNullOrEmpty(results))
      {
         results = "differences: {\n";
      }
      results += "\t" + objectName + ": {\n";
      results += "\t\tfield: " + key + ",\n";
      results += "\t\toldvalue: " + (null==v1)? "null" : v1.ToString() + ",\n";
      results += "\t\tnewvalue: " + (null==v2)? "null" : v2.ToString() + "\n";
      results += "\t}\n";
    }
