Thanks all for the information.
Below are my original codes that will create the xml file physically:
private void convertDataTableToXML()
{
// Duplicate the table and add it to a temporary DataSet
DataSet dataset = new DataSet();
DataTable datatable = premiumTable.Copy();
dataset.Tables.Add(datatable);
// Save the temporary DataSet to XML
StreamWriter streamwriter = new StreamWriter("C://XMLDoc.xml");
dataset.WriteXml(streamwriter);
streamwriter.Close();
}
However, instead of using StreamWriter, I change to MemoryStream.
Below is the codes:
MemoryStream ms = new MemoryStream();
dataset.WriteXml(ms);
ms.Close();
How to I reference the xml file created by MemoryStream for later use? Eg, I
need to extract a node value from the xml file.
Thanks.
Thanks,

the following command to do it. However, there will be existing file be
created. Is there any other ways which there wont be file created? I only
need to store it in memory.
DataSet.WriteXml can write to a stream, a TextWriter, an XmlWriter or a
file. You could use a MemoryStream, a StringWriter, or an XmlWriter
backed by either of them.
