Generate JSON array with WCF

Question

I\'m developing a WCF web service that returns this:

{
    \"allFormsResult\": [
        {
            \"FormId\": 1,
            \"FormName\": \"Formulario 1\"
         


        

Answer 1

The problem is here:

namespace ADM
{
    [ServiceContract]
    public interface IRestServiceImpl
    {
        [OperationContract]
        [WebInvoke(Method = "GET",
            ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Wrapped,
            UriTemplate = "forms/")]
        List<FormContract> allForms();
    }
}

I have to use it this way:

namespace ADM
{
    [ServiceContract]
    public interface IRestServiceImpl
    {
        [OperationContract]
        [WebInvoke(Method = "GET",
            ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Bare,
            UriTemplate = "forms/")]
        List<FormContract> allForms();
    }
}

Changing BodyStyle:

BodyStyle = WebMessageBodyStyle.Bare

This behavior can also be set as default through the Web.Config, without the need to add the attributes directly to the contract.

<services>
  <service name="MyServiceNameSpace.MyServiceClass">
    <endpoint
        address="http://yourservicedomain.ext/MyServiceClass.svc/"
        binding="webHttpBinding"
        contract="MyServiceNameSpace.MyServiceContract"
        behaviorConfiguration="MyEndpointBehavoir"
        listenUri="/" />        
  </service>      
</services>

<behaviors>
  <endpointBehaviors>
    <behavior name="MyEndpointBehavoir">
      <webHttp defaultOutgoingResponseFormat="Json" defaultBodyStyle="Bare"/>
    </behavior>        
  </endpointBehaviors>
</behaviors>
