Question

I want to export a CSV file to a datagridview. I need to create the file schema.ini. But I don’t know, how can I create it?

There is my code:

    public DataTable exceldenAl(string excelFile)
    {
        try
        {
            string fileName = Path.GetFileName(excelFile);
            string pathOnly = Path.GetDirectoryName(excelFile);
            string cmd = "Select * From [" + fileName + "$]";

            string cnstr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pathOnly + "\\;Extended Properties=\"Text;HDR=Yes;FORMAT=Delimited\"";
            OleDbConnection ocn = new OleDbConnection(cnstr);
            ocn.Open();
            OleDbCommand command = new OleDbCommand(cmd,ocn);
            OleDbDataAdapter adap = new OleDbDataAdapter(command);

            DataTable dt = new DataTable();
            dt.Locale = CultureInfo.CurrentCulture;
            adap.Fill(dt);
            return dt;
        }
        finally {
        }
    }


    private void btnExcelReader_Click(object sender, EventArgs e)
    {
        string dosya;
        string cevap;
        openFileDialog1.ShowDialog();
        dosya = openFileDialog1.FileName.ToString();
        ClsExcelReader er = new ClsExcelReader();
        cevap = er.exceldenAl(dosya).ToString();
        dataGridView1.DataSource = cevap;
        //listViewExcelOku.DataBindings =
    }
}

Open up notepad and create a file similar to this:

[YourCSVFileName.csv]
ColNameHeader=True
Format=CSVDelimited
DateTimeFormat=dd-MMM-yyyy
Col1=A DateTime
Col2=B Text Width 100
Col3=C Text Width 100
Col4=D Long
Col5=E Double

Modify the above file to fit your specific data schema. Save it as SCHEMA.ini in the same directory where your *.CSV file is located.

Read this link (Importing CSV File Into Database), it is a good example to get you up and understanding how the Schema.ini works
