This article focuses on "how to implement WCF data contract". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to implement the WCF data contract.

In WCF service programming, we know that WCF data contracts define remote access objects and service operation methods that can be invoked, while WCF data contracts define custom data types to be transferred between the server and the client. In the WCF project, declare a type DataContract so that the type can be serialized and passed between the server and the client.

Only when a class is declared as DataContract can objects of that type be passed, and only the properties of the class can be passed, and you need to add a DataMember declaration before the property life so that the property can be serialized. The default property is not transferable. The methods of the class are not passed. The type of WCF data contract can be controlled in more detail, a member attribute can be excluded from the serialization scope, and the client program will not get any information about the excluded member attributes, including definitions and data. The code is as follows:

[DataContract] / / data contract attribute declares class MyDataContract {[DataMember (Name = "MyName")] / / data member tag, supports alias definition public string Name {get; set;} [DataMember (Name = "MyEmail")] / / data member tag, and supports alias definition public string Email {get; set;} [DataMember] / / data member tag public string Mobile {get; set } / / there is no [DataMember] declaration, public string Address {get; set;} will not be serialized

The above class is declared as DataContract, and some properties are declared as DataMember (data members). Can be serialized for client transmission. The Address member property is not declared as DataMember, so no information about the Address is transmitted when data is exchanged. Members declared as DataMember can also customize aliases visible to the client, such as:

[DataMember (Name = "MyName")] / / data member tag, which supports alias definition. At this point, I believe you have a deeper understanding of "how to implement the WCF data contract". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
