Question

Environment is VS2008, .Net 3.5

The following C# code (note the specified encoding of UTF8)

XmlWriterSettings settings = new XmlWriterSettings (); StringBuilder sb  = new StringBuilder(); settings.Encoding = System.Text.Encoding.UTF8; settings.Indent   = false; settings.NewLineChars = '\n'; settings.ConformanceLevel =  System.Xml.ConformanceLevel.Document;  XmlWriter writer = XmlWriter.Create (sb, settings); {    // Write XML data.    writer.WriteStartElement ('CCHEADER');    writer.WriteAttributeString ('ProtocolVersion', '1.0.0');    writer.WriteAttributeString ('ServerCapabilities', '0x0000000F');    writer.WriteEndElement ();    writer.Flush (); } 

Actually generates the XML (>< omitted because SO barfs on them):

?xml version=’1.0′ encoding=’utf-16′?
CCHEADER ProtocolVersion=’1.0.0′ ServerCapabilities=’0x0000000F’ /

Why do I get the wrong encoding generated here ? What am I doing wrong ?

Answer 1

I suspect it’s because it’s writing to a StringBuilder, which is inherently UTF-16. An alternative to get round this is to create a class derived from StringWriter, but which overrides the Encoding property.

I believe I’ve got one in MiscUtil – but it’s pretty trivial to write anyway. Something like this:

public sealed class StringWriterWithEncoding : StringWriter {     private readonly Encoding encoding;      public StringWriterWithEncoding (Encoding encoding)     {         this.encoding = encoding;     }      public override Encoding Encoding     {         get { return encoding; }     } }
