Complicate json object?

[Billy Zhang]

I have a asp.net app, in client I create a Complicate json string,
for example: { a: ‘a’, b : { b ; ‘b’ } }

If .net has corresponding type, it could be
deserialized, for example:

DataContractJsonSerializer serializer = new
DataContractJsonSerializer(typeof(A));
using (MemoryStream ms = new
MemoryStream(Encoding.Unicode.GetBytes(jsonText))) {
//serializer.WriteObject(ms);
//return Encoding.Default.GetString(ms.ToArray());
A a = (A)serializer.ReadObject(ms);
return a;

}

But the question is if there are no corresponding .net type, in .net 3.5
could we serialize it into anonymous type? Or any other way to solve this
problem?

Hi Billy,

As for the WCF JSON serializer, I'm afraid so far it doesn't support
serialization upon anonymous type. Actually all the .NET serialization
formatter cannot serialize with anonymous type. I've tried directly
serialize it via the following code but it report a type is not serialable
error:

====================
var obj = new { Name = "abc", Title = "abc" };

DataContractJsonSerializer jsonserializer = new
DataContractJsonSerializer(obj.GetType());

MemoryStream ms = new MemoryStream();
ms.Close();

jsonserializer.WriteObject(ms, obj);
=========================

Also, anonymous's autogenerated type name is random(based on runtime,
appdomain info) which is not reliable and persistable in districuted
environment. For your scenario, if you have some complex data blocks which
will be constructed on the fly(without an existing definted type), I think
it would be better to manually pass the data as string parameter and
manually parse it in code. How do you think?
