What is DataContractSerializer and how its different from XmlSerializer?
DataContractSerializer can serialize both private and public types. DataContractSerializer does not need any default constructor before serializing any type. 9. DataContractSerializer does not give more control over the generated xml structure compared to the XmlSerializer.
What is data contract serializer?
Remarks. Use the DataContractSerializer class to serialize and deserialize instances of a type into an XML stream or document. Most important, the DataContractSerializer is used to serialize and deserialize data sent in Windows Communication Foundation (WCF) messages.
Does WCF use XML?
Windows Communication Foundation (WCF) can use two different serialization technologies to turn the data in your application into XML that is transmitted between clients and services, a process called serialization.
What is serialization in WCF service?
The process forms a sequence of bytes into a logical object; this is called an encoding process. At runtime when WCF receives the logical message, it transforms them back into corresponding . Net objects. This process is called serialization.
What is DataContractSerializer in WCF?
Windows Communication Foundation (WCF) uses the DataContractSerializer as its default serialization engine to convert data into XML and to convert XML back into data. The DataContractSerializer is designed to serialize data contract types. For more information, see Using Data Contracts and Serializable Types.
Is DataContractSerializer thread safe?
Serialization. DataContractSerializer, it says: Instances of this class are thread safe except when the instance is used with an implementation of the IDataContractSurrogate or DataContractResolver.
Which WCF binding does not support reliable session?
The system-provided bindings that support a reliable session as an option but don’t enable one by default include: WSHttpBinding. WSFederationHttpBinding. NetTcpBinding.
Which hosting mechanism is supported by WCF?
Hosting Mechanisms − Various activation mechanisms are there for WCF hosting, i.e., IIS (Internet Information Service), WAS (Windows Activation Service), Self-hosting and Windows Service, but a web service is hosted only by IIS.
What is DataContract and Datamember in C#?
A datacontract is a formal agreement between a client and service that abstractly describes the data to be exchanged. In WCF, the most common way of serialization is to make the type with the datacontract attribute and each member as datamember.
What is XmlSerializer C#?
The XmlSerializer enables you to control how objects are encoded into XML, it has a number of constructors. It allows you to serializeand deserialize objects into and from XML documents. It enables youto control how objects are encoded into XML. The class constructoraccepts the object type to serialize.
How is the datacontractserializer class used in XML?
Use the DataContractSerializer class to serialize and deserialize instances of a type into an XML stream or document. For example, you can create a type named Person with properties that contain essential data, such as a name and address.
Which is serialization class inherits from xmlobjectserializer class?
Both the DataContractSerializer class and the NetDataContractSerializer class inherit from the XmlObjectSerializer and are used to serialize and deserialize objects that conform to data contract rules (objects created using the DataContractAttribute and the DataMemberAttribute ).
Why does the XmlSerializer fall back to the WCF?
For example it does not support serializing an object’s members as XML attributes. When you write a WCF client that calls a service, WCF will generate a proxy class that defaults to using the DataContractSerializer and falls back to the XmlSerializer if the service uses features that the DataContractSerializer does not support.
How to serialize an object in net data contract?
Net Data Contract Serializer The following example shows a method named WriteObjectWithInstance that includes an XmlObjectSerializer as a parameter. The method serializes an object using either the DataContractSerializer or NetDataContractSerializer by calling the WriteObject method.
