列表框的文件需要按文件创建日期/时间排序 [英] Files to listbox need ordering by file creation date/time

问题描述

我有以下填充列表框但我需要先按创建日期/时间排序文件。最新的列表顶部。听起来很容易，但我无法弄清楚如何。任何帮助非常感谢！提前致谢

I have the following that populates a listbox but I need the files ordering by creation date/time first. Newest top of the list. Sounds easy enough but I just cant figure out how. Any help much appreciated! Thanks in advance

For Each file As String In Directory.GetFiles("C:\ProgramData\Folder\Temp\", "*.pdf")

    lstPDFs.Items.Add(Path.GetFileNameWithoutExtension(file))

Next

我尝试了什么：



谷歌搜索但似乎无法理解它

What I have tried:

Googled but cant seem to get my head around it

推荐答案

这个怎么样：

How about this:

List<FileInfo> lstFiles = new List<FileInfo>();
foreach (var file in Directory.GetFiles(@"C:\yourfolder\", "*.pdf"))
{
    FileInfo fInfo = new FileInfo(file);
    lstFiles.Add(fInfo);
}

var lstPDFs = lstFiles.OrderBy(f => f.CreationTime).Select(f => f.FullName).ToList();

很抱歉，注意到这是一个VB.Net问题。不是我的强项，比如这样：

Sorry, just noticed this is a VB.Net question. Not my strong suit, something like this:

Dim lstFiles As List(Of FileInfo) = New List(Of FileInfo)()

For Each file In Directory.GetFiles("C:\yourfolder\", "*.pdf")
    Dim fInfo As FileInfo = New FileInfo(file)
    lstFiles.Add(fInfo)
Next

Dim lstPDFs = lstFiles.OrderBy(Function(f) f.CreationTime).[Select](Function(f) f.FullName).ToList()

对不起，我发布评论时没有时间......这是使用LINQ的概念控制台应用快速验证。

Sorry I didn't have the time earlier when I posted my comment... here is the quick proof of concept console app utilizing LINQ.

Dim FileList = New DirectoryInfo("C:\FolderName\").GetFiles("*.pdf")
Dim DisplayList = From EachFile In FileList Order By EachFile.CreationTime

For Each DisplayFile In DisplayList
  Console.WriteLine(DisplayFile.Name)
Next

可能会进一步简化，但像'LittleGreenDude'VB不是我的强项

Could probably be simplified further but like 'LittleGreenDude' VB is not my forte
