No, the DataContractAttribute is not required – WCF will infer serialization rules.
What is Datacontract and DataMember?
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 serialization in WCF?
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 a DataContract?
A data contract is a formal agreement between a service and a client that abstractly describes the data to be exchanged. That is, to communicate, the client and the service do not have to share the same types, only the same data contracts.
What is DataMember attribute?
Data Member are the fields or properties of your Data Contract class. You must specify [DataMember] attribute on the property or the field of your Data Contract class to identify it as a Data Member.
What is message contract in WCF?
A message contract is used to control the structure of a message body and serialization process. It is used to send/access the information in the soap header. By use of a Message Contract we can customize the parameters sent using a SOAP message between the client and the server.
How fault contract is implemented in WCF?
Raise the exception from the service by creating an instance and assigning properties of the custom exception.
Step 1: Defining the type using Data Contract. Step 2: Decorate the service operation with the FaultContract. Step 3: Raise the exception from the service.
How do you create 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 is DataContract namespace?
DataContract is under namespace System. Runtime. Serialization. During design time, DataContract Attribute is used to indicate which class should be represented as XSD. DataMember Attribute indicates which class member to be used in external representation.
What is system runtime serialization?
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.
What is data contract serialization?
DataContractAttribute Class (System.Runtime.Serialization)
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.
