如何重命名VB.NET中的文件以具有唯一的后缀？ [英] How to rename files in VB.NET to have a unique suffix?

问题描述

我了解如何在 VB.NET 中重命名文件，代码在我的帖子末尾。但是，我想知道是否可以重命名文件，如果该文件存在，然后重命名并将+1添加到文件名？

I understand how to rename a file in VB.NET as I use in the code at the end of my post. However, I was wondering if it's possible to rename a file and if the file exists then to rename it and add +1 to the file name?

因此，如果我运行了

首次运行

My.Computer.FileSystem.RenameFile("c:\test\test.txt", "c:\test\NewName.txt")

'再次运行它，但应添加+1，因为该文件已经存在，因此应为 c：\test\NewName1.txt

'Run it again, but it should add +1 as the file will already exists, so it should be "c:\test\NewName1.txt"

My.Computer.FileSystem.RenameFile("c:\test\test.txt", "c:\test\NewName.txt")

更新

我决定而不是重命名和+1，最好只加上日期戳，这样对于像我一样挣扎的人来说：

I decided rather than rename and +1, it would be better to just date stamp it, so for anyone who struggles as I did:

My.Computer.FileSystem.RenameFile("c:\test\test.txt", "Test" & Format(Date.Now, "ddMMyy") & ".txt")

推荐答案

If File.Exists(filePath) Then
  ' Give a new name
Else
  ' Use existing name
End If

路径 类具有许多处理文件路径的方法。

The Path class has many methods for dealing with file paths.

Path.GetFileNameWithoutExtension(filePath)
