I am using c#.

Now I am looking to create a “JSONHelper” class, which will Serialize and Deserialize the JSON string data. In my current scenario, I am getting below format string from my web-service which returns JSON type.

I have got a method in my C# code which calls a web-service method, which returns the string JSON type data. See below example.

string userDetails = myWebService.GetMember(username, Password, out Result);

so userDetails value is 

{"FullName":"Manoj Singh","username":"Manoj","Miles":2220,"TierStatus":"Gold","TierMiles":23230,"MilesExpiry":12223,"ExpiryDate":"31 January 2011","PersonID":232323,"AccessToken":"sfs23232s232","ActiveCardNo":"232323223"}

Now I want to write JSONHelper Class in which there will be methods to Serialize and Deserialize the string type of JSON, and will return the dictionary type of values.

    You can use the JavaScriptSerializer class in the System.Web.Script.Serialization namespace:

    JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
object result = jsonSerializer.DeserializeObject(jsonString);

    Assuming your jsonString represents a object this should return a dictionary. But you will need to check the type carefully as there is no guarantee it won’t return an IEnumerable for example if you give it a json list.

    Better still you can use a strongly type deserialization:

    If you know the return signature of your web method this is a far better solution.
