问题描述
我会保持简短...我之前问过这个问题，但没有人回答.我想从一个文件夹中获取多个图像，并将它们添加到一个数组中.这不起作用，有人可以明确告诉我该怎么做吗?谢谢！
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!
在表单加载时:
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\turcotd\Desktop\ITLPers", "*.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
谢谢！！！
推荐答案
首先，我向您展示了如何获取 DirectoryInfo 不是来自上面的 FileInfo！
First, i've showed you how to get the images of a DirectoryInfo not from a FileInfo like above!
我在我对您上一个问题的回答中使用了强类型List(Of FileInfo) 而不是数组，因为它更好，甚至比一个 ArrayList .您可以像访问数组中的项目一样访问列表中的项目(通过索引或foreach").
I've used a strong typed List(Of FileInfo) in my answer on your previous question instead of an Array because it's a lot better, even than an ArrayList. You can access the items in a List the same you would access the items in an Array(via Index or "foreach").
如果您仍然坚持使用数组，则只需使用 ToArray-Extension 而不是 ToList.例如:
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
查看 FileInfo-Class 以了解进一步的信息.例如，您需要调用 FileInfo.Name 获取图像名称(不带路径的文件名)或 FileInfo.FullName 获取完整路径.
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.
所以这应该有效:
Dim dir = New IO.DirectoryInfo("C:\Users\turcotd\Desktop\ITLPers")
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
