如何列出硬盘驱动器中某个文件夹下的所有文件名？ [英] how to list all files names under a folder in hard drive?

问题描述

我想使用vb.net列出硬盘驱动器中文件夹下所有存在的文件名，我不知道如何。首先，我选择一个包含folderbrowser组件的文件夹，接下来，我列出所有文件

I want to list all files names exist under folder in hard drive with vb.net , and i don't know how.First ,i choose a folder with folderbrowser component, next,i list all files

这是我的代码（仅用于选择文件夹）

Here is my code (only for choose a folder)

   dossier_disque.ShowDialog()
    txt_folder.Text = dossier_disque.SelectedPath

列出所有文件，我尝试用于每个，但不正确

for list all files , i tried to use for each , but it's not correct

我尝试列出文件时的代码

my code when i tried to list file

        Dim files() As String = Directory.GetFiles(txt_folder.Text)
    For Each a In CStr(files.Count)
        folder_hard.Rows.Add(Directory.GetFiles(txt_folder.Text))
    Next

folder_hard是网格名称
txt_folder是a的名称文件夹路径

folder_hard is a grid name txt_folder is a name of a folder path

使用此代码，结果只能在网格中两次看到第一个文件

With this code , the result , i can see only the first file twice in grid

推荐答案

您的f出现了问题或每个循环：
CStr（）将值转换为字符串。
因此，您的for循环遍历files数组中文件数字符串中的每个char。
因此将其更改为：

There is a problem with your for each loop: CStr() converts values into strings. So your for loop is looping through each char in the string of the number of files in the files array. So change it to:

For Each a In files

然后a将是files数组中的每个文件名。
如果要将每个添加到网格，则需要将该行更改为：

Then a will be each file name in the files array. If you want to add each to your grid you need to change that line to :

folder_hard.Rows.Add(a)

所以这应该起作用：

Dim files() As String = Directory.GetFiles(txt_folder.Text)
For Each a In files
    folder_hard.Rows.Add(a)
Next
