Solution 3

The StringWriter class explained here http://msdn.microsoft.com/en-us/library/system.io.stringwriter.aspx[^] can be used to write DataSet values to a string in xml format. The StringWriter class uses the StringBuilder object. There are other overloads to specify the StringBuilder and FormatProvider.

VB

Dim sw As New StringWriter()
ds1.WriteXml(sw)
Console.WriteLine(sw.ToString())
