使用ODBC在.NET中进行CSV上传

Question

Hi i have CSV upload code in .net

In C#

 string strConnString = "Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=D:\\csv;Extensions=asc,csv,tab,txt;Persist Security Info=False";
            DataSet ds;
            using (OdbcConnection oConn = new OdbcConnection(strConnString))
            {
                using (OdbcCommand oCmd = new OdbcCommand())
                {
                    oCmd.Connection = oConn;
                    oCmd.CommandType = System.Data.CommandType.Text;
                    oCmd.CommandText = "select * from [my.csv]";

                    OdbcDataAdapter oAdap = new OdbcDataAdapter();
                    oAdap.SelectCommand = oCmd;

                    ds = new DataSet();
                    oAdap.Fill(ds, "my");
                    oAdap.Dispose();                     
                    ds.Dispose();
                }
            }

In .VB

  Dim strConnString As String = "Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=D:\\csv;Extensions=asc,csv,tab,txt;Persist Security Info=False"

        Dim lOdbcConnection As New OdbcConnection(strConnString)
        '            lOdbcConnection.ConnectionString = strConnString
        'lOdbcConnection.Open()
        Using lOdbcCommand As New OdbcCommand, lOdbcDataAdapter As New OdbcDataAdapter
            lOdbcCommand.Connection = lOdbcConnection
            lOdbcCommand.CommandType = System.Data.CommandType.Text
            lOdbcCommand.CommandText = "select * from [my.csv]"

            lOdbcDataAdapter.SelectCommand = lOdbcCommand
            Dim ds As New DataSet()
            lOdbcDataAdapter.Fill(ds, "my")
            ds.Dispose()

            lOdbcDataAdapter.Dispose()

In C# is working fine But in .VB its giving error when filling the dataset .-

ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

what I am doing wrong?

You don't need to escape the \\ character in VB.NET strings so "Dbq=D:\\\\csv" should be "Dbq=D:\\csv". That's why your data source isn't found.
