推荐答案

您是否尝试过?这不是很难.

程序员执行此操作的方法是-使用for循环并遍历DataTable中的行.针对另一个循环中的每一行检查每一行的必需列值.

有句非常有名的谚语-尝试，您就会成功！

祝你好运！

Have you tried doing it? It isn''t very hard.

A programmer''s way of doing this is to - use for loop and iterate through the rows in the DataTable. Check each row''s required column value against every rows in another loop.

There is a very famous saying - Try and you shall succeed!

Good luck!
