Question

I am creating an ASHX that returns XML however it expects a path when I do

XmlWriter writer = XmlWriter.Create(returnXML, settings) 

But returnXML is just an empty string right now (guess that won’t work), however I need to write the XML to something that I can then send as the response text. I tried XmlDocument but it gave me an error expecting a string. What am I missing here?

If you really want to write into memory, pass in a StringWriter or a StringBuilder like this:

using System; using System.Text; using System.Xml;  public class Test {     static void Main()     {         XmlWriterSettings settings = new XmlWriterSettings();         settings.Indent = true;                 StringBuilder builder = new StringBuilder();          using (XmlWriter writer = XmlWriter.Create(builder, settings))         {             writer.WriteStartDocument();             writer.WriteStartElement('root');             writer.WriteStartElement('element');             writer.WriteString('content');             writer.WriteEndElement();             writer.WriteEndElement();             writer.WriteEndDocument();         }         Console.WriteLine(builder);     } } 

If you want to write it directly to the response, however, you could pass in HttpResponse.Output which is a TextWriter instead:

using (XmlWriter writer = XmlWriter.Create(Response.Output, settings)) {     // Write into it here }
