Json中的WCF REST返回列表

Question

I want to respond a List in WCF with Rest in JSON format. How can i do that to receive my Users? Endpointconfiguration already works.

[OperationContract(Name = "GetUsers")]
[WebGet(UriTemplate = "GetUsers", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
List<User> GetUsers();

Answer 1

My problem was that i had a class defined in the IInterface.cs. But in that class I had a subclass, lets say for example "dog".

Now I set up the [DataContract] for "user", but not for "dog", which was unfortunately included into "user".

Solution: "For every class that should be returned, dont forgett the [DataContract]"

The tricky thing on that stuff is, you dont even have any warnings, exceptions etc.

Greets and thanks!
