C#: XmlTextWriter.WriteElementString fails on empty strings?

Question

I\'m using XmlTextWriter and its WriteElementString method, for example:

XmlTextWriter writer = new XmlTextWriter(\"filename.xml\",         


        

Answer 1

Leaving this here in case someone needs it; since none of the answers above solved it for me, or seemed like overkill.

FileStream fs = new FileStream("file.xml", FileMode.Create);

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;

XmlWriter w = XmlWriter.Create(fs, settings);
w.WriteStartDocument();
w.WriteStartElement("tag1");
w.WriteStartElement("tag2");
w.WriteAttributeString("attr1", "val1");
w.WriteAttributeString("attr2", "val2");
w.WriteFullEndElement();
w.WriteEndElement();
w.WriteEndDocument();

w.Flush();
fs.Close();

The trick was to set the XmlWriterSettings.Indent = true and add it to the XmlWriter.

Edit:

Alternatively you can also use

w.Formatting = Formatting.Indented;

instead of adding an XmlWriterSettings.
