排序由OpenFileDialog检索的文件 [英] sorting files retrieved by OpenFileDialog

问题描述

我对OpenFileDialog检索多个

选定文件的顺序不满意。我希望它们在日期顺序中，从最旧到最新，但默认情况下

它们以文件名输入，从最后到第一位。


唯一似乎相关的属性是排序，所有这一切是颠倒

文件名顺序。我需要日期订单。我已经找到了答案但是

什么都没有出现。任何想法？

I''m not happy with the order in which OpenFileDialog retrieves multiple
selected files. I want them in Date order, oldest to newest, but by default
they come in by filename, last to first.

The only property that seems relevant is Sort, and all that does is invert
the filename order. I need Date order. I''ve searched for an answer but
nothing has come up. Any ideas?

推荐答案

看看以下是否有帮助

注意：没有编译它，所以可能有拼写错误或语法错误


''Comparer Class

Public Class CompareFileDates

实现IComparer

功能IComparer.Compare（ ByVal a As Object，ByVal b As Object）As Integer

返回DateTime.Compare（System.Io.File.GetLastWriteTime（DirectCast（a，

String）），System .Io.File.GetLastWriteTime（DirectCast（b，String）））

结束功能

结束班级


''代码按日期排序文件

Array.Sort（文件，新的CompareFileDates（））;

我认为anwser将创建两个数组并将选定的文件

添加到一个数组中作为FileInfo（路径）和另一个数组为返回的每个项添加FileInfo

（路径）.DateCreated，然后执行[Array] .Sort

（dateArray，fileInfoArray），生成的fileInfoArray将是按

dateArray排序。更多相关内容： http://msdn.microsoft.com/library/default.asp?

另一种方法是在类中实现IComparer（只有一个

函数）将所有选中的文件作为FileInfo抛出s然后

[数组] .Sort（fileInfoArray，ComparerClass）更多信息

这里： http://msdn.microsoft.com/library/de...l=/library/en-

us / cpref / html / frlrfsystemcollectionsicomparerclasstopic.asp

I think the anwser would be to create two arrays and add the selected files
to one array as FileInfo(path) and the other array add FileInfo
(path).DateCreated for each item returned, then do [Array].Sort
(dateArray,fileInfoArray), the resulting fileInfoArray will be sorted by
dateArray. More on this here:http://msdn.microsoft.com/library/default.asp?
url=/library/en-us/cpref/html/frlrfsystemarrayclasssorttopic.asp

The other way would be to implement IComparer in a class (which is only one
function) throw all the selected files in an array as FileInfo''s and then
[Array].Sort(fileInfoArray,ComparerClass) More info

感谢您的快速回复！


这对我来说是外来的功能，并且在插入代码之后我收到了一些错误，所以我显然不得不玩它一点。我很高兴你让我开始了！

Thanks for the quick response!

That''s foreign functionality to me and I received a number of errors after
inserting the code so I''m obviously going to have to play with it a bit. I
appreciate you getting me started!
