How can I convert a DataTable to an XML file in C#?

Question

I want to convert a DataTable to an XML file in C#. How can I do this?

Answer 1

You can use DataTable.WriteXml Method.

Here is an example;

How can i convert my datatable into XML using C# 2.0?

string result;
using (StringWriter sw = new StringWriter()) {
dataTable.WriteXml(sw);
result = sw.ToString();
}

If you don't actually need a string but read-only, processable XML, it's a better idea to use MemoryStream and XPathDocument:

XPathDocument result;
using (MemoryStream ms = new MemoryStream()) {
dataTable.WriteXml(ms);
ms.Position = 0;
result = new XPathDocument(ms);
}
