What is a DataContractSerializer?
Most important, the DataContractSerializer is used to serialize and deserialize data sent in Windows Communication Foundation (WCF) messages. Apply the DataContractAttribute attribute to classes, and the DataMemberAttribute attribute to class members to specify properties and fields that are serialized.
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.
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.
Which namespace is used for serialization in WCF?
When this parameter is set to true , a special method of encoding object references, which only WCF understands, is used. When set to true , the XML code example now resembles the following. The “ser” namespace refers to the standard serialization namespace, http://schemas.microsoft.com/2003/10/Serialization/ .
What is data contract attribute?
Data contract is an agreement between client and Service about the data, which is to be exchanged between them. and deserialize(opposite of serialization) in order to exchange between the client and the Service. Data Contract attribute can be annotated on a class, Enum or even a structure but not on an interface.
What is data contract in C#?
A data contract is a formal agreement between a service and a client that abstractly describes the data to be exchanged. A data contract precisely defines, for each parameter or return type, what data is serialized (turned into XML) to be exchanged.
What is Knowntype C#?
According to MSDN the KnownTypeAttribute class allows you to specify, in advance, the types that should be included for consideration during deserialization. The WCF service generally accepts and returns the base type. If you expect the service to accept and return an inherited type then we use the knowntype attribute.
What is data contract and data member in C#?
How do you write a data contract?
To create a basic data contract for a class or structure
- Declare that the type has a data contract by applying the DataContractAttribute attribute to the class.
- Define the members (properties, fields, or events) that are serialized by applying the DataMemberAttribute attribute to each member.
What’s the difference between XmlSerializer and datacontractserializer?
The XmlSerializer class supports a much narrower set of types than the DataContractSerializer class, but allows much more control over the resulting XML and supports much more of the XML Schema definition language (XSD) standard. It also does not require any declarative attributes on the serializable types.
How to serialize an XML into a namespace?
I’m looking for a way with C# which I can serialize a class into XML and add a namespace, but define the prefix which that namespace will use. Ultimately I’m trying to generate the following XML:
Is the XmlSerializer class unique to WCF or ASP.NET?
The XmlSerializer class is not unique to WCF. It is the same serialization engine that ASP.NET Web services use. The XmlSerializer class supports a much narrower set of types than the DataContractSerializer class, but allows much more control over the resulting XML and supports much more of the XML Schema definition language (XSD) standard.
How to initialize a new datacontractserializer class?
Initializes a new instance of the DataContractSerializer class to serialize or deserialize an object of the specified type. Initializes a new instance of the DataContractSerializer class to serialize or deserialize an object of the specified type and settings.
