Here is what we did :

public class XmlCDataWriter : XmlTextWriter       {           public XmlCDataWriter(TextWriter w): base(w){}           public XmlCDataWriter(Stream w, Encoding encoding): base(w, encoding){}           public XmlCDataWriter(string filename, Encoding encoding): base(filename, encoding){}           public override void WriteString(string text)           {               if (text.Contains("<"))               {                   base.WriteCData(text);               }               else               {                   base.WriteString(text);               }           }       }

And then to use the class :

public StringBuilder CDataOverwiriteMethod(Rss20FeedFormatter formatter)       {           var buffer = new StringBuilder();           //could be streamwriter as well           using (var stream = new StringWriter(buffer))           {               using (var writer = new XmlCDataWriter(stream))               {                   var settings = new XmlWriterSettings() {Indent = true};                   using (var xmlWriter = XmlWriter.Create(writer, settings))                   {                       formatter.WriteTo(xmlWriter);                   }               }           }           return buffer;       }
