Parser - CSV files to Oracle database

Question

Hello all,
I wrote a csv parser that parse csv files to micorsoft access database. Now I need to parse the dataset to oracle database. This is part of my exporter class
class MdbExporter : IExporter
/// <summary>
/// Exportiert das DataSet in eine Mdb-Datei.
/// </summary>
/// <param name="ds">Zu exportierendes DataSet.</param>
public void Write(DataSet ds, string[] names)
string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + names[0] + ";";
Console.WriteLine("Exporting to database {0} ...", names[0]);
Any ideas how can I do that?
Thanks for any replay in advance.

I wrote a parser that goes through several folders containing csv files, reads them and creates a dataset that contains 15 tables ( which I need for an intranet application after that). I succeed to write a MDB exporter that export this dataset to microsoft access database. Now I need an exporter that will export my dataset to ORACLE database. Below is the full code for my MDB exporter:
public void Write(DataSet ds, string[] names)
string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + names[0] + ";";
Console.WriteLine("Exporting to database {0} ...", names[0]);
DbConnection connection = new OleDbConnection(conStr);
try
connection.Open();
catch (DbException e)
ConsoleEx.WriteException(true, e, "Unable to open database: {0}", names[0]);
throw;
DbCommand command = connection.CreateCommand();
foreach (DataTable table in ds.Tables)
Console.WriteLine("\tDeleting table: {0}", table.TableName);
// delete old tables
command.CommandText = string.Format("drop table {0}", table.TableName);
TryExecute(command, false);
// create new
Console.WriteLine("\tCreating new table: {0}", table.TableName);
string[] columnStrings = new string[table.Columns.Count];
for (int i = 0; i < table.Columns.Count; i++)
columnStrings[i] = "`" + table.Columns.ColumnName + "`" + " varchar";
command.CommandText = string.Format("create table {0} ({1})",
table.TableName, string.Join(", \n", columnStrings));
TryExecute(command, true);
// add rows
for (int row = 0; row < table.Rows.Count; row++)
for (int col = 0; col < table.Columns.Count; col++)
columnStrings[col] = "'" + Convert.ToString(table.Rows[row].ItemArray[col]) + "'";
command.CommandText = string.Format("insert into {0} values ({1})",
table.TableName, string.Join(", \n", columnStrings));
TryExecute(command, true);
connection.Close();
I need similar exporter to Oracle database. Starting with SQL LOADER from the beginning its really not a good in my opinion since I am almost done with this approach.
Any help would be appreciated.
