Re: Clearing file content with XmlWriter

 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();
}
