|
|
WriteObject(XmlDictionaryWriter, Object) | Serializes an object to XML that may be mapped to JavaScript Object Notation (JSON). Writes all the object data, including the starting XML element, content, and closing element, with an XmlDictionaryWriter. (Overrides XmlObjectSerializer.WriteObject(XmlDictionaryWriter, Object).) |

WriteStartObject(XmlWriter, Object) | Writes the opening XML element for serializing an object to XML that can be mapped to JavaScript Object Notation (JSON) using an XmlWriter. (Overrides XmlObjectSerializer.WriteStartObject(XmlWriter, Object).) |
Use the DataContractJsonSerializer class to serialize instances of a type into a JSON document and to deserialize a JSON document into an instance of a type. For example, you can create a type named Person with properties that contain essential data, such as a name and address. You can then create and manipulate an instance of the Person class and write all of its property values in a JSON document for later retrieval. This JSON document can later be deserialized into the Person class or another class with an equivalent data contract.
If an error occurs during the serialization of an outgoing reply on the server or the reply operation throws an exception for some other reason, it may not get returned to the client as a fault.

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
Referenced Assembly is wrong for Silverlight 5
You have to reference System.ServiceModel.Web to get access to DataContractJsonSerializer

Base Class Mismatch
In Silverlight 4, the class inherits from System.Object (as documented on the Silverlight version of this page http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer(v=VS.95).aspx). In .Net Framework 4, the class inherits from XmlObjectSerializer as documented.
Sample code
Example here: How to: Serialize and Deserialize JSON Data http://msdn.microsoft.com/en-us/library/bb412179.aspx
Silverlight users
For Silverlight (4) users you'll find this in System.ServiceModel.Web.dll.

Assembly mismatch
Regarding the problem mentioned earlier, i want to say this article is right: this class resides in System.Runtime.Serialization dll for the .NET Framework 4. The problem lies in the assembly version: although the class is contained in the version 4.0.0.0 assembly, you won't find it in earlier versions. This class was migrated from System.ServiceModel.Web to System.Runtime.Serialization in .NET 4.
Thus, if you are using .NET 3.5 SP1 or earlier, you should look for this class in System.ServiceModel.Web dll.

The assembly mentioned in the documentation is not correct
No, the page is correct. It's System.Runtime.Serialization.dll.
