C# Data Table Type problem on importing from CSV

Question

I am using the following

string sql = @"SELECT * FROM [" + fileName + "]";

using (OleDbConnection connection = new OleDbConnection(
                  @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathOnly +
                  ";Extended Properties=\"Text;HDR=" + header + "\""))
using (OleDbCommand command = new OleDbCommand(sql, connection))
using (OleDbDataAdapter adapter = new OleDbDataAdapter(command))
{
    DataTable dataTable = new DataTable();
    dataTable.Locale = CultureInfo.CurrentCulture;
    adapter.Fill(dataTable);

    intCurrentTableRowCount = dataTable.Rows.Count;

    return dataTable;
}

The problem is the 12,13,14 columns are returned as a date field (which would be no problem but some of dates are European ie 24/12/2021) so those data table fields are blank.

Is there a way around this issue? Not even sure where to start.

Answer 1

You cast your column in varchar. If you need datetime in your code, after import you can add new column in the dataset and in a loop use Datetime.TryParse for parse the date.

Is not the most performant solution but it s will works.
