Answer 1

Where you want to validate json, on server side or on client side.
Assuming you want to do it on server side, try deserializing the json string. if it breaks, then its not a valid json. Use JavaScriptSerializer for deserializing purpose

var serializer = new JavaScriptSerializer();
var result = serializer.Deserialize<Dictionary<string, object>>(json);
