System.Runtime.Serialization Namespace

The System.Runtime.Serialization namespace contains classes that can be used for serializing and deserializing objects. Serialization is the process of converting an object or a graph of objects into a linear sequence of bytes for either storage or transmission to another location. Deserialization is the process of taking in stored information and recreating objects from it.

The ISerializable interface provides a way for classes to control their own serialization behavior. Classes in the System.Runtime.Serialization.Formatters namespace control the actual formatting of various data types encapsulated in the serialized objects.

Formatters that serialize and deserialize objects to and from a particular format can be found in the System.Runtime.Serialization.Formatters namespace.

  Class Description
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps CollectionDataContractAttribute When applied to a collection type, enables custom specification of the collection item elements. This attribute can be applied only to types that are recognized by the DataContractSerializer as valid, serializable collections.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps ContractNamespaceAttribute Specifies the CLR namespace and XML namespace of the data contract.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps DataContractAttribute Specifies that the type defines or implements a data contract and is serializable by a serializer, such as the DataContractSerializer. To make their type serializable, type authors must define a data contract for their type.
Public class Supported in .NET for Windows Store apps DataContractResolver Provides a mechanism for dynamically mapping types to and from xsi:type representations during serialization and deserialization.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps DataContractSerializer Serializes and deserializes an instance of a type into an XML stream or document using a supplied data contract. This class cannot be inherited.
Public class Supported in .NET for Windows Store apps DataContractSerializerSettings Specifies data contract serializer settings.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps DataMemberAttribute When applied to the member of a type, specifies that the member is part of a data contract and is serializable by the DataContractSerializer.
Public class Supported in .NET for Windows Store apps DateTimeFormat Specifies date-time format options.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps EnumMemberAttribute Specifies that the field is an enumeration member and should be serialized.
Public class ExportOptions Represents the options that can be set for an XsdDataContractExporter.
Public class ExtensionDataObject Stores data from a versioned data contract that has been extended by adding new members.
Public class Formatter Provides base functionality for the common language runtime serialization formatters.
Public class FormatterConverter Represents a base implementation of the IFormatterConverter interface that uses the Convert class and the IConvertible interface.
Public class FormatterServices Provides static methods to aid with the implementation of a Formatter for serialization. This class cannot be inherited.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps IgnoreDataMemberAttribute When applied to the member of a type, specifies that the member is not part of a data contract and is not serialized.
Public class ImportOptions Represents the options that can be set on an XsdDataContractImporter.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps InvalidDataContractException The exception that is thrown when the DataContractSerializer or NetDataContractSerializer encounters an invalid data contract during serialization and deserialization.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps KnownTypeAttribute Specifies types that should be recognized by the DataContractSerializer when serializing or deserializing a given type.
Public class NetDataContractSerializer Serializes and deserializes an instance of a type into XML stream or document using the supplied .NET Framework types. This class cannot be inherited.
Public class ObjectIDGenerator Generates IDs for objects.
Public class ObjectManager Keeps track of objects as they are deserialized.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps OnDeserializedAttribute When applied to a method, specifies that the method is called immediately after deserialization of an object in an object graph. The order of deserialization relative to other objects in the graph is non-deterministic.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps OnDeserializingAttribute When applied to a method, specifies that the method is called during deserialization of an object in an object graph. The order of deserialization relative to other objects in the graph is non-deterministic.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps OnSerializedAttribute When applied to a method, specifies that the method is called after serialization of an object in an object graph. The order of serialization relative to other objects in the graph is non-deterministic.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps OnSerializingAttribute When applied to a method, specifies that the method is during serialization of an object in an object graph. The order of serialization relative to other objects in the graph is non-deterministic.
Public class OptionalFieldAttribute Specifies that a field can be missing from a serialization stream so that the BinaryFormatter and the SoapFormatter does not throw an exception.
Public class SafeSerializationEventArgs Provides data for the SerializeObjectState event.
Public class SerializationBinder Allows users to control class loading and mandate what class to load.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps SerializationException The exception thrown when an error occurs during serialization or deserialization.
Public class SerializationInfo Stores all the data needed to serialize or deserialize an object. This class cannot be inherited.
Public class SerializationInfoEnumerator Provides a formatter-friendly mechanism for parsing the data in SerializationInfo. This class cannot be inherited.
Public class SerializationObjectManager Manages serialization processes at run time. This class cannot be inherited.
Public class SurrogateSelector Assists formatters in selection of the serialization surrogate to delegate the serialization or deserialization process to.
Public class Supported by Portable Class Library Supported in .NET for Windows Store apps XmlObjectSerializer Provides the base class used to serialize objects as XML streams or documents. This class is abstract.
Public class XmlSerializableServices Contains methods for reading and writing XML.
Public class XPathQueryGenerator When given a class representing a data contract, and metadata representing a member of the contract, produces an XPath query for the member.
Public class XsdDataContractExporter Allows the transformation of a set of .NET Framework types that are used in data contracts into an XML schema file (.xsd).
Public class XsdDataContractImporter Allows the transformation of a set of XML schema files (.xsd) into common language runtime (CLR) types.

  Structure Description
Public structure SerializationEntry Holds the value, Type, and name of a serialized object.
Public structure Supported by Portable Class Library Supported in .NET for Windows Store apps StreamingContext Describes the source and destination of a given serialized stream, and provides an additional caller-defined context.

  Interface Description
Public interface IDataContractSurrogate 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).
Public interface IDeserializationCallback Indicates that a class is to be notified when deserialization of the entire object graph has been completed. Note that this interface is not called when deserializing with the XmlSerializer (System.Xml.Serialization.XmlSerializer).
