将子目录移动到 C# 中主目录的父目录中

Question

I'm looking to figure out how to move a directory out of its parent, into its parents, parent. It sounds a little odd, so I'll visualize it. We have Folder A, B, C, C Being in B, etc. I need to move folder C out of B, and into directory A.

I've already attempted it using this (extractPath is folder A, FolderB is, well folder B):

Directory.Move(Directory.GetDirectories(extractPath + @"\FolderB")[0],Directory.GetParent(extractPath + @"\FolderB").ToString());

However from this error, it appears to be trying to move it: System.IO.IOException: 'The file 'C:\Users\user\Documents\FolderA\FolderB\FolderC\ExampleFile.png' already exists.'

I should be using Path.Combine rather than adding the two, but I just need it to work, I'll fix that later.

Thanks for your help.

Edit: I rewrote my code to be easier to read, and probably lower the chance of me messing something up

String newDir = Directory.GetDirectories(extractPath + @"\FolderB")[0]; //Should return folder C
Directory.Move(newDir, extractPath); //Moves folder C to folder A.

Answer 1

I fixed it: It was a combination of a few minor details but the main issue is this:

I had

Directory.Move(newDir, extractPath);

You've got to add the name of the file of newDir, my original folder im moving. You can get the name of just that folder with

Path.GetFileName(newDir);

You will then have

Directory.Move(newDir, extractPath + Path.GetFileName(newDir));
