VB.NET Sort files in directory by alphanumeric

问题:

How do I sort the files in this directory below by alphanumeric? An example of a file: 12325_2011.jpg

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load     If Not Page.IsPostBack Then         Dim di As New IO.DirectoryInfo(ImagePath)         Dim imageArray As IO.FileInfo() = di.GetFiles()         Dim image As IO.FileInfo          'list the names of all images in the specified directory          For Each image In imageArray             CheckBoxList1.Items.Add(image.Name)         Next     End If End Sub

回答1:

Just modify your existing For Each loop like this:

For Each image In imageArray.OrderBy(Function(i) i.Name)     CheckBoxList1.Items.Add(image.Name) Next

回答2:

You could use the sorted list class instead of your image array:

e.g.

For each Item in di.GetFiles    'Add image url to sorted list Next   For Each Item in SortedList     'Add to checkbox list Next
