XmlTextWriter to StreamWriter problem

[GaryDean]

I'm using an XmlTextWriter and it's various methods such as
WriteElementString, WriteStartElement, WriteEndElement, etc to create an xml
document. When I instantiate the XmlTextWriter to a file...

XmlTextWriter mytw = new XmlTextWriter("c:\\temp\\myfile.xml", null)

Everything writes properly and a good XML document gets created.

However if I instantiate the XmlTextWriter to a memoryStream...

Stream myMemoryStream = new MemoryStream();
TextWriter myStreamWriter = new StreamWriter(myMemoryStream);
XmlTextWriter mytw = new XmlTextWriter(myStreamWriter);

and then examine myMemoryStream, the last endelement</mydocdoes not get
written and after a mytw.Flush() it still isn't written. Then after a
mytw.Close() the mytw.basestream and myMemoryStream are null.

So writing to a file is successful because the end tag gets written to disk,
apparently by the Close() that also nulls the stream.

So, how can I get that last tag written and have access to the stream before
it is destroyed?

If you have the necessary WriteEndElement() and/or WriteEndDocument()
calls then I don't see a problem and have never experienced one.
Can you post example code where the closing tag is missing?

Hi Gary,
Thanks for Martin's reply.

Frankly, I haven't met such issue before. I agree with Martin, your code
snippet will help on research very much. Would you please post some example
code where the closing tag is missing?

Additionally, there is a sample about how to Read XmlTextWriter to the
memory stream instead writing to the file. Hope it helps.
