public static Name ConvertToName(string json)
{
var ser = new JavaScriptSerializer();
return ser.Deserialize(json);
}
static void Main(string[] args)

string json=”{‘FirstName’:’Swapnil’, ‘LastName’:’Gaikwad’,’Values’:[0,1,2]}”;
var name = Program.ConvertToName(json);
Console.WriteLine(name.FirstName);
Console.ReadLine();

return ser.Deserialize(json);
is really
return ser.Deserialize(json);
