制作文件夹和复制文件 [英] Making folder and copying file

问题描述

我希望我的应用程序在驱动器 C 的特定文件夹中查找文件(比如 C:\myFolder\abc.mdb)，如果找到就给一个消息，如果没有，请在驱动器 C:\ 中创建文件夹，然后复制文件.

I want my application to look for a file in drive C's specific folder (say C:\myFolder\abc.mdb), if found just give a message if not, make the folder in drive C:\ and then copy the file.

如何做到这一点?谢谢弗坎

How to do this? Thanks Furqan

推荐答案

您可以使用 File、Directory 和 Path 对象在System.IO如下图:

You could use the File, Directory, and Path objects in the System.IO as shown below:

Imports System.IO

...

Dim path As String = "C:\myFolder\abc.mdb"

If File.Exists(path) Then
     'TODO write code to create message'
Else
     Dim folder As String = Path.GetDirectoryName(path)
     If Not Directory.Exists(folder) then
         Directory.CreateDirectory(folder)
     End If
     'TODO code to copy file from current location to the newly created directory path'
     'i.e. File.Copy(FileToCopy, NewCopy)'
End If
