Question

I ll keep this short and simple... I asked this question before, but It wasn t answered. I d like to get several images from a folder, and add them to an array. This is not working, can someone explicitly tell me how to do it? Thanks!

表格装载:

Private Sub Button1_Add(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim PictureArray As New List(Of Image)
    For Each item As String In Directory.GetFiles("C:Users	urcotdDesktopITLPers", "*.jpg", IO.SearchOption.AllDirectories)
        Dim _Image As Image = Image.FromFile(item)
        PictureArray.Add(_Image)
    Next

    If (i < 6) Then
        Dim pb As New PictureBox
        Me.FlowLayoutPanel1.Controls.Add(pb)
        pb.Image = PictureArray(i)
        i = i + 1

enter image description here Thanks!!!

Answer 1

首先,i ve向您展示了如何获取DirectoryInfo 。不要从上述档案信息中找到!

I ve在回答您先前的问题,而不是“Array” ,因为这是一个好兆头, rel=“nofollow noretinger” ,甚至比“ArrayList 。您可以查阅清单中的物品,也可查阅阿雷拉(通过索引或“前列”)中的物品。

If you anyway insist on using an Array, you simply need to use the ToArray-Extension instead of ToList. For example:

Dim imageArray = dir.GetFiles("*.jpg", IO.SearchOption.AllDirectories).ToArray

Look at the FileInfo-Class for further informations. For example you need to call FileInfo.Name to get the image-name(filename without path) or FileInfo.FullName to get the Full-Path.

因此,这项工作应当:

Dim dir = New IO.DirectoryInfo("C:Users	urcotdDesktopITLPers")
Dim images = dir.GetFiles("*.jpg", IO.SearchOption.AllDirectories).ToList
Dim pictures As New List(Of PictureBox)
For Each img In images
    Dim picture As New PictureBox
    picture.Image = Image.FromFile(img.FullName)
    pictures.Add(picture)
Next

Answer 2

An image is not a datatype you can use fileinfo to read the images into an byte array.

Tim s answer here at your previous question does that very well it just puts it into a list. You can then call thelist.toarray and now your list is an array.

EDIT: i found this link for you it will help.

这是一个很简单的过程。

问题在于你把形象视为一种扼杀或煽动,而不是一种。它是一批 by。这种希望有助于。
