//Dataset To Xls
ExportDataSetToCsvFile(DS,@"C:\\");

internal static void ExportDataSetToCsvFile(DataSet _DataSet, string DestinationCsvDirectory)
{
    try
    {
        foreach (DataTable DDT in _DataSet.Tables)
        {
            String MyFile = @DestinationCsvDirectory + "\\_" + DDT.TableName.ToString() + DateTime.Now.ToString("yyyyMMddhhMMssffff") + ".csv";//+ DateTime.Now.ToString("ddMMyyyyhhMMssffff")
            using (var outputFile = File.CreateText(MyFile))
            {
                String CsvText = string.Empty;

                foreach (DataColumn DC in DDT.Columns)
                {
                    if (CsvText != "")
                        CsvText = CsvText + "," + DC.ColumnName.ToString();
                    else
                        CsvText = DC.ColumnName.ToString();
                }
                outputFile.WriteLine(CsvText.ToString().TrimEnd(','));
                CsvText = string.Empty;

                foreach (DataRow DDR in DDT.Rows)
                {
                    foreach (DataColumn DCC in DDT.Columns)
                    {
                        if (CsvText != "")
                            CsvText = CsvText + "," + DDR[DCC.ColumnName.ToString()].ToString();
                        else
                            CsvText = DDR[DCC.ColumnName.ToString()].ToString();
                    }
                    outputFile.WriteLine(CsvText.ToString().TrimEnd(','));
                    CsvText = string.Empty;
                }
                System.Threading.Thread.Sleep(1000);
            }
        }
    }
    catch (Exception Ex)
    {
        throw Ex;
    }  
}
