Question

I’ve got a function creating some XmlDocument:

public string CreateOutputXmlString(ICollection<Field> fields) {     XmlWriterSettings settings = new XmlWriterSettings();     settings.Indent = true;     settings.Encoding = Encoding.GetEncoding('windows-1250');      StringBuilder builder = new StringBuilder();     XmlWriter writer = XmlWriter.Create(builder, settings);      writer.WriteStartDocument();     writer.WriteStartElement('data');     foreach (Field field in fields)     {         writer.WriteStartElement('item');         writer.WriteAttributeString('name', field.Id);         writer.WriteAttributeString('value', field.Value);         writer.WriteEndElement();     }     writer.WriteEndElement();     writer.Flush();     writer.Close();      return builder.ToString(); } 

I set an encoding but after i create XmlWriter it does have utf-16 encoding. I know it’s because strings (and StringBuilder i suppose) are encoded in utf-16 and you can’t change it.
So how can I easily create this xml with the encoding attribute set to ‘windows-1250’? it doesn’t even have to be encoded in this encoding, it just has to have the specified attribute.

edit: it has to be in .Net 2.0 so any new framework elements cannot be used.

You need to use a StringWriter with the appropriate encoding. Unfortunately StringWriter doesn’t let you specify the encoding directly, so you need a class 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; }     } } 

(This question is similar but not quite a duplicate.)

EDIT: To answer the comment: pass the StringWriterWithEncoding to XmlWriter.Create instead of the StringBuilder, then call ToString() on it at the end.
