Will XmlSerializer ever create empty documents

Answer 1

We've encountered this problem several times at $WORK, with the symptom being an empty file of the correct size but filled with zero bytes.

The solution we found was to set the WriteThrough value on the FileStream:

using (Stream file = new FileStream(settingTemp, FileMode.Create,
                                   FileAccess.Write, FileShare.None,
                                   0x1000, FileOptions.WriteThrough))
{
   using (StreamWriter sw = new StreamWriter(file))
   {
      ...
   }
}

Answer 2

The only reason I can think that this would happen is that this line:

(new XmlSerializer(this.GetType())).Serialize(textWrite, this);

throws an exception and the textwriter is created and disposed without ever having anything written to it. I'd look at your log for errors.

What does

Static.Backup.XmlFile(FileSaveLocation);

do?
