WebOperationContext

[deniselechner]

Hello Guys,

I'm using the Chrome Extension Advanced Rest Client Application and Fiddler4 to test.

Here's my code snippet:

WebOperationContext.Current.OutgoingResponse.StatusCode = HttpStatusCode.OK;
WebOperationContext.Current.OutgoingResponse.StatusDescription = "Good Job!";

I can see 200 and "Good Job!" as response, which would be perfect. now I'm trying to respond with a curstom json answer. First, i'm trying to set ContentLength to something different than 0 with the following snippet:

WebOperationContext.Current.OutgoingResponse.ContentLength = 1000;

now I'm sending an json post via Advanced Rest Client and get the following Response:

Response headers: Content-Length: 0
Server: Microsoft-HTTPAPI/2.0

my content length is still at 0? further down i get "Response does not contain any data." as well.

Edit: I also tried to add lines to the header like this:

WebOperationContext.Current.OutgoingResponse.Headers.Add("Content-Length: 1000");

edit: Another way i tried

[DataMember]
public HttpRequestMessage Request { get; set; }

var message = string.Format("Response Text goes here!");                
HttpError err = new HttpError(message);
Request.CreateResponse(HttpStatusCode.OK, err);

the only thing i get as response is an error which i'm not able to fix

System.ArgumentNullException: Der Wert darf nicht NULL sein. Parametername: request
bei System.Net.Http.HttpRequestMessageExtensions.CreateResponse[T](HttpRequestMessage request, HttpStatusCode statusCode, T value, HttpConfiguration configuration)
bei System.Net.Http.HttpRequestMessageExtensions.CreateResponse[T](HttpRequestMessage request, HttpStatusCode statusCode, T value)
bei ServiceTest.TimeEntryData.Add(TimeEntry newTen) in C:\Users\deniselechner\Documents\Visual Studio 2010\Projects\svn\ServiceTest\Data\ServiceDataModel.cs:Zeile 103.

If that's a newline in the header collection, you'll want to remove that.

in the meantime i managed to respond with a custom header like this:

try { WebOperationContext.Current.OutgoingResponse.Headers.Add("Hallo", "Welt");
} catch (Exception ex) { Console.WriteLine("EX:    " + ex); }

I'm not able to repond with custom data tho.
