DataContractJsonSerializer Constructor (Type, IEnumerable<Type>, Int32, Boolean, IDataContractSurrogate, Boolean)

Initializes a new instance of the DataContractJsonSerializer class to serialize or deserialize an object of the specified type. This method also specifies a list of known types that may be present in the object graph, the maximum number of graph items to serialize or deserialize, whether to ignore unexpected data or emit type information, and a surrogate for custom serialization.

Namespace:  System.Runtime.Serialization.Json
Assembly:  System.Runtime.Serialization (in System.Runtime.Serialization.dll)

public DataContractJsonSerializer(
	Type type,
	IEnumerable<Type> knownTypes,
	int maxItemsInObjectGraph,
	bool ignoreExtensionDataObject,
	IDataContractSurrogate dataContractSurrogate,
	bool alwaysEmitTypeInformation


Type: System.Type
The type of the instances that is serialized or deserialized.
Type: System.Collections.Generic.IEnumerable<Type>

Type: System.Runtime.Serialization.IDataContractSurrogate
An implementation of the IDataContractSurrogate to customize the serialization process.
