Hi everybody,

I am trying to deserialize a json string which I have serialized before with the
Newtonsoft Json library.
using (StreamReader sr = new StreamReader(s))
{
   json = sr.ReadToEnd();
}
object o = JsonConvert.DeserializeObject(json);
return o;

After the deserialisation the var o contains a JObject, but I want the source
object which I have serialized. How can I get the real object back.
I know there is a JsonConvert.DeserializeObject<t>() function, but I do not know what type of object it is, because I am serializing a lot of different objects.
When I serialize my objects I store the type of the object in the json string,
so how can I tell the serializer to use the stored type for deserializing.

Thanks in advance
Manu

I am sure Marcus' solution will answer your question, but, if you are struggling with NewtonSoft Json, may I recommend you take a look at Mehdi Gholam's fantastic json facility here on CP: http://www.codeproject.com/Articles/159450/fastJSON ... includes detailed performance comparisons of his work, fastJson, and NewtonSoft's Json. His facility is much faster, and offers more options to deserialize complex .NET objects.

Solution 2

JsonSerializerSettings set = new JsonSerializerSettings();
set.TypeNameAssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Simple;
set.TypeNameHandling = TypeNameHandling.All;
set.Formatting = Newtonsoft.Json.Formatting.None;


When using this settings for serializing and deserializing
it works, now i get the real object and not a JObject.
