Hi all,
I have this code from Microsoft to create an xml file; but I can't find a way to write it to a file to my Windows Phone 8.1 project.

Dim sb As StringBuilder = New StringBuilder()
Dim xws As XmlWriterSettings = New XmlWriterSettings()
xws.OmitXmlDeclaration = True
xws.Indent = True

Using xw = XmlWriter.Create(sb, xws)
    Dim doc As XDocument = New XDocument(<Child><GrandChild>some content</GrandChild></Child>)
    doc.WriteTo(xw)
End Using

Console.WriteLine(sb.ToString())

Open in new window

Pass a Stream to the XmlWriter.Create method instead of a StringBuilder.
Not sure FileStream is available on Windows Phone. I guess you can use an IsolatedStorageFileStream

Nope that didn't work either.
I did manage to fix it though using a different technique....

Dim XMLDOC$ = txtSAFE_NAME.Text & ".xml"
        Dim sf As Windows.Storage.StorageFolder = RSCatalog_Loc
        Dim st As StorageFile = Await sf.CreateFileAsync(XMLDOC$)

        Dim xDoc As New XDocument(
            New XDeclaration("1.0", "utf-8", "yes") _
            , New XElement("RUSAFE" _
                , New XElement("INFOTBL",
                    New XElement("FILE_NAME", New XText(txtSAFE_NAME.Text.ToString())))))

st = Await sf.CreateFileAsync(XMLDOC$, CreationCollisionOption.OpenIfExists)
        Dim ws = TryCast(Await st.OpenStreamForWriteAsync(), Stream)
        xDoc.Save(ws)
 _

Open in new window


This does work; but the only issue i'm having wih it is that sometimes the data Is not saved.  I'm wondering if the Await function is causing a problem or perhaps I have to close the file. Strange, it works sometimes and not other..

Think I fixed it.
ws.dispose on the end.

I need to test it some more but it seems to be consistant at the moment.

I figured out a completely different way of solving the problem as all other solutions did not work.
