Initializes a new instance of the DataContractSerializer 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, parameters to ignore unexpected data, whether to use non-standard XML constructs to preserve object reference data in the graph, and a surrogate for custom serialization.

The following example creates an instance of the DataContractSerializer that specifies the type to serialize or deserialize and an instance of a IEnumerable<(Of <(T>)>) to contain the known types used during serialization or deserialization. The code also sets the ignoreExtensionDataObject and preserveObjectReferences parameters to true, and specifies an implementation of the IDataContractSurrogate interface to handle legacy types (types that do not have the DataContractAttribute attribute applied). For more information, see the IDataContractSurrogate documentation.
