CSV到GridView比CRUD操作

Question

我正在做一个Job记者应用程序，直到现在我所做的是，导入CSV文件到网格视图并通过将其保存在数据表中显示它，现在我想要的是更新和将记录保存回csv文件，我没有使用任何SQL或任何类型的数据库，是否可以这样做？ 请帮助我，我必须在两个小时内交付项目。 该项目是C＃Win窗体。 也帮我在我如何序列化它上传到FTP服务器。 代码在这里是...... 私人无效openProjectToolStripMenuItem_Click_1（对象发件人，EventArgs的）{

保存自己的一些头痛，并检查了，ClosedXML，并利用这个答案可以Can I save an EXCEL worksheet as CSV via ClosedXML?创建CSV文件。

System.IO.File.WriteAllLines(csvFileName, 
    worksheet.RowsUsed().Select(row => 
     string.Join(";", row.Cells(1, row.LastCellUsed(false).Address.ColumnNumber) 
          .Select(cell => cell.GetValue<string>())) 
));
