using System.Xml;
using System.Data.SqlClient;

public class Sample
  public static void Main()
     DataSet dsNorthwind = new DataSet();

     //Create the connection string.           
     String sConnect;
     sConnect="Data Source=localhost;Integrated Security=SSPI;Initial Catalog=Northwind";     

     //Create a connection object to connect to the northwind db.
     SqlConnection nwconnect = new SqlConnection(sConnect);

     //Create a command string to select all the customers in the WA region.
     String sCommand = "Select * from Customers where Region='WA'";

     //Create an adapter to load the DataSet.
     SqlDataAdapter myDataAdapter = new SqlDataAdapter(sCommand, nwconnect);

     //Fill the DataSet with the selected records.

     //Load the document with the DataSet.
     XmlDataDocument doc = new XmlDataDocument(dsNorthwind);
