VB全扫描 [英] VB Full scan

问题描述

好了，我想让用户从组合框中选择一个根目录(例如，"C:\").一旦发生这种情况，将启用开始"按钮，并在文本框中显示带有我已加载文件名的文本文件.用户单击开始以扫描C驱动器，并且标签显示计算机正在寻找的文本文件中的目录和文件名.........

我对递归并不满意，并且已经尝试了好几天了.我有了递归的想法，并且知道这可能是扫描计算机文件夹和子文件夹的最有效方法，但是我真正需要的是一个完整的示例单词，而哪个对象控制着哪一行代码……请我非常想了解递归，并且需要帮助使我的扫描仪搜索整个目录而不仅仅是一个级别.

Ok to start I would like to have the user select a root directory from a combobox (Example, "C:\"). Once that happens the start button is enabled and the text file with my loaded file names is displayed in a textbox. The user clicks start to scan the C drive and the label shows the directory and file name from the text file that the computer is looking for.........

I am no good with recursion and have been trying to learn it for days. I get the idea of recursion and know it may be the most efficient way to scan a computers folders and sub folders but what I truly need is a full example word for word and what object controls what line of code...... Please I am desperate to understand recursion and need help to make my scanner search the entire directory and not just one level.

推荐答案

虽然我建议您尝试学习递归，实际上，这里不需要. IO名称空间中的GetFiles方法将使您可以找到给定目录及其子目录中的所有文件.

像这样的东西:

While I recommend that you try to learn recursion, actually it''s not needed here. The GetFiles method in the IO namespace will let you find all files in a given directory AND it''s subdirectories.

Something like this:

Imports System.IO

Dim dir As New DirectoryInfo("C:\")
For Each foundFile As FileInfo In dir.GetFiles("*.*", SearchOption.AllDirectories)
    'Do Magic here

Next foundFile

在这种情况下，AllDirectories标志指定它应递归遍历所有子目录...

In this case, the AllDirectories flag specifies that it should loop through all subdirectories recursively...

一个示例(只为您编写！): [
