DataContractSurrogate | Gets a surrogate type that is currently active for a given IDataContractSurrogate instance. Surrogates can extend the serialization or deserialization process. |

|
EmitTypeInformation | Gets or sets the data contract JSON serializer settings to emit type information. |
|
|
IgnoreExtensionDataObject | Gets a value that specifies whether unknown data is ignored on deserialization and whether the IExtensibleDataObject interface is ignored on serialization. |

|
KnownTypes | Gets a collection of types that may be present in the object graph serialized using this instance of the DataContractJsonSerializer. |
|
|
MaxItemsInObjectGraph | Gets the maximum number of items in an object graph that the serializer serializes or deserializes in one read or write call. |

|
GetType | Gets the Type of the current instance. (Inherited from Object.) |

|
IsStartObject(XmlDictionaryReader) | Gets a value that specifies whether the XmlDictionaryReader is positioned over an XML element that represents an object the serializer can deserialize from. (Overrides XmlObjectSerializer.IsStartObject(XmlDictionaryReader).) |

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.
