            }
            //dt.Columns.Add("EmployeeID", typeof(int));

            string[] cust = "a bc c".Split(" ");
            dt.Rows.Add(new object[] { dt.Rows.Count + 1, cust[0], cust[1] });
            dt.WriteXml("Employees.xml", XmlWriteMode.WriteSchema);

Using DataTable to read Xml

using System;
using System.Data;
using System.Collections.Generic;
using System.Text;
    class Program
    {
        static void Main(string[] args)
        {
            DataTable dt = new DataTable("Employees");
            dt.ReadXml("Employees.xml");
            DataTableReader dtr = dt.CreateDataReader();
            while (dtr.Read())
            {
                Console.WriteLine(dtr["EmployeeID"]);
                Console.WriteLine(dtr["FirstName"]);
                Console.WriteLine(dtr["LastName"]);
            }
