如何计算根驱动器中的所有目录? [英] How to count all directories in root drive?

问题描述

您好，为什么我的标签不计算C:\
中的所有目录和子目录，我有些困惑
我不希望计数文件，我只想对我选择的驱动器中的所有现有文件夹进行快速计数.

这是我到目前为止的内容:

Hello I am a bit stuck as to why my label will not count all the directories and sub directories in C:\

I do not wish to count the files, I only wish to get a quick count for all existing Folders in which ever drive I choose.

Here is what i have so far:

Try
                Dim Root As New DirectoryInfo("SearchPath eg. C:\")
                Dim Dirs As DirectoryInfo() = Root.GetDirectories("*.*", SearchOption.AllDirectories)
                Dim count As Integer = Dirs.Length
                For Each DirectoryName In Dirs
                    Label12.Text = count
                Next
            Catch ex As UnauthorizedAccessException
            End Try

如果尝试以此加载程序，则会收到一条路径访问冲突消息，指出文档和设置受到保护.

一个快速的例子将不胜枚举，或者解释为什么它不起作用将是同样的.

If I try to load the program with this I get a path access violation saying documents and settings is protected.

A quick example would be greatly appricated or an explaination of why this does not work would be just as equal.

thank you in advance!!

推荐答案

请改用Directory.GetDirectories("c:\").

此外，DirectoryInfo采用有效路径，因此应为DirectoryInfo("C:\").

Use Directory.GetDirectories("c:\") instead.

Also DirectoryInfo takes a valid path, so it should be DirectoryInfo("C:\").
