Question

我想将CSV文件导出到datagridview.我需要创建文件schema.ini.但我不知道,我怎么能创造它呢？

有我的代码:

    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 =
    }
}

打开记事本并创建一个类似于此的文件:

[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

修改上述文件以适合您的特定数据模式.将其作为SCHEMA.ini保存在*.CSV文件所在的同一目录中.
