IDataContractSurrogate Interface

Provides the methods needed to substitute one type for another by the DataContractSerializer during serialization, deserialization, and export and import of XML schema documents (XSD).

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

public interface class IDataContractSurrogate

Use the IDataContractSurrogate when using the DataContractSerializer if you need to do one of the following: substitute one type or object for another, or to dynamically generate schema variations. For a sample application, see DataContract Surrogate Sample. For more information about data contracts, see Using Data Contracts.

At run time, you can find the specific DataContractSerializer for any operation in a service by using the OperationDescription to find the DataContractSerializerOperationBehavior instance. For more information about implementing the interface to create a surrogate, see Data Contract Surrogates.

You can also use the IDataContractSurrogate to affect the import and export of XML schemas when you are using the XsdDataContractExporter and XsdDataContractImporter classes. You can do so by assigning the IDataContractSurrogate to the DataContractSurrogate property of the ExportOptions class, or to the DataContractSurrogate property of the ImportOptions class. For more information, see Schema Import and Export.

The following example shows an implementation of the IDataContractSurrogate interface. The code substitutes the serialization of the Person type for a PersonSurrogated class.
