问题描述

嗨 我使用datagridview填充csv文件中的数据.data是员工的打卡时间.datagridview没有数据源(由于需要进行一些计算而手动添加了行).是否有可能将datagridview数据检索到数据表或数据集中?因为我想根据打孔日期过滤行.我的目的是避免循环?有任何建议吗?

推荐答案

使用linq是个好主意.
但是，如果您要使用循环手动添加行，则只需将其添加到DataTable中而不是网格中，然后将网格的DataSource设置为DataTable.

Using linq is a good idea.
But if you are manually adding rows using a loop, then just add them to a DataTable instead of gird and set the DataSource of the grid to the DataTable.

您知道LINQ吗?
有一个LINQ to CSV，可以帮助减少这种事情所需的代码量.参见 http ://blogs.msdn.com/b/wriju/archive/2009/05/24/linq-to-csv-getting-data-the-way-you-want.aspx [

Do you know LINQ?
There is a LINQ to CSV that can help reduce the amount of code you need for this kind of thing. See http://blogs.msdn.com/b/wriju/archive/2009/05/24/linq-to-csv-getting-data-the-way-you-want.aspx[^] for example. You can bind the result of the LINQ query to a DataGrid after applying filter.
