31//or Without JSON.Net
32//You can utilize .Net framework 4.5 System.Json namespace ,like:
33
34string jsonString = "someString";
35try
36{
37    var tmpObj = JsonValue.Parse(jsonString);
38}
39catch (FormatException fex)
40{
41    //Invalid json format
42    Console.WriteLine(fex);
43}
44catch (Exception ex) //some other exception
45{
46    Console.WriteLine(ex.ToString());
47}//(But, you have to install System.Json through Nuget package manager using 
48//command: PM> Install-Package System.Json -Version 4.0.20126.16343 on Package Manager Console)
