DataTable to CSV generator

This code will generate the .csv (Comma separator file) from the Data source like DataTable or XML strings.

    protected void CreateCSV(object sender,EventArgs e)
        {
            MemoryStream ms = new MemoryStream();
            DataSet ds = new DataSet();
            ds.ReadXml(@"d:\students.xml");
            if (ds.Tables[0].Rows.Count > 0)
            {
                StreamWriter writer = new StreamWriter(ms);
                writer.AutoFlush = true;

                foreach (DataColumn column in ds.Tables[0].Columns)
                {
                    writer.Write(column.ColumnName.ToString() + ",");
                }
                writer.WriteLine();

                foreach (DataRow drow in ds.Tables[0].Rows)
                {
                      writer.Write(drow["Name"].ToString() + "," + Convert.ToDateTime(drow["DOJ"]).ToShortDateString().ToString() + "," + drow["Height"].ToString() + ",");
                      writer.WriteLine();
                }
            }
            using (FileStream file = new FileStream("D:\\file5.csv", FileMode.Create, FileAccess.Write))
            {
                
                ms.WriteTo(file);
            }
        }
