Question

I have been writing some Web services to be used by a few different client apps and i was trying to write a web service method that simply outputs an RSS XML Feed.

I can create the XML using an XmlTextWriter Object

Then i have tryed outputing to the Response (like i have done in the past when its an aspx page) but this only works it the return type is void (and still doesnt seem to output properly)

Then i tryed making the return type a string and using a StringWriter to output the xml from the XmlTextWriter but the output is then wrapped in a tag.

How can i do this?

Answer 1

Obviously create the interfaces and rest of the WCF service as normal.

Mark the class with the following attribute

[ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)] 

And then this function

public Stream GetRSS() {  string output;  //output = some_text;  MemoryStream ms = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(output));  WebOperationContext.Current.OutgoingResponse.ContentType = 'text/xml';  return ms; }
