Question

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

Answer 1

Another way to get this done is by adding the data table to dataset and calling the GetXml() on the dataset.In addition to this dataset is equipped with the WriteXml() and ReadXml() for writing/reading the XML directly to/from a file path or stream.

DataSet ds = new DataSet();
ds.Tables.Add(dt1); // Table 1
ds.Tables.Add(dt2); // Table 2...
...
string dsXml= ds.GetXml();
...
using (StreamWriter fs = new StreamWriter(xmlFile)) // XML File Path
{
      ds.WriteXml(fs);
}
