如何使用Silverlight在javascript中启用WCF Web服务

Question

We have a wcf web service which is developed as a silverlight enabled wcf web service for accessing database from silverlight application. Now we would like to use the same WCF service to be used from JavaScript. Is it possible to call silverlight enabled wcf web service in javascript

Answer 1

Yes it is possible, you just need to add the Json Endpoint to your service contract and convert your method to return Json data,

For example,

    [OperationContract]
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "login/{username}/{password}",BodyStyle = WebMessageBodyStyle.Bare)]

    UserAuth login(string username, string password);

Answer 2

Yes it is possible.

Modify the class definition [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class CustomersService { ///// }

Leave silverlight methods as it is and add Json methods like the following.

[OperationContract] [WebGet(ResponseFormat = WebMessageFormat.Json)] public List GetCustomers(int d) { return List; }
