Is there a way to clear out a file using XmlWriter before writing the final content and without having to first delete the file?

 brettr,

You could open the file in Truncate mode to clear the file while opening.  However, I believe this will only work if the file already exists.  See the code below:

using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
using (IsolatedStorageFileStream isoStream = new IsolatedStorageFileStream("test.xml", FileMode.Truncate, isoStore))
{
    XmlWriter w = XmlWriter.Create(isoStream);
    w.WriteStartElement("Test");
    w.WriteRaw("Stuff");
    w.WriteEndElement();
    w.Flush();
    isoStream.Flush();
    isoStream.Close();
}
