移动后恢复文件 [英] Restore files after a move

问题描述

所以...我做了一个哎呀。一个相当大的一个。我写了一些代码来搜索文件夹和所有子目录，并提取任何PDF文件。我打算做的是将PDF复制到一个新的位置，而我所做的就是移动它们。代码一夜之间运行，因为我知道我将处理70K +文件，并且在尝试做其他事情时不想放慢计算机的速度。

我需要做的就是将它们移回去。这里的问题是每个文件都是一个唯一的名称，来自一个名称非常相似的文件夹。例如：文件名ULT00004605_20161105.pdf来自名为ULT00004605的子目录。

有没有人知道如何索引子目录并将它们放回原点？

我用来移动它们的代码是我试过了什么？ 。当我应该使用CopyTo时，你可以看到我使用了MoveTo。



我尝试了什么：

So... I made an oops. A rather large one. I wrote some code to search through folders and all sub directories and pull any PDF file found. What I meant to do was to copy the PDF to a new location, instead what I did was move them. The code ran overnight since I knew I would be dealing with 70K+ files and didn't want to slow my computer while trying to do other things.
What I need to do is move them back. The problem here is that each file is a unique name and came from a folder with a very similar name. For example: File name ULT00004605_20161105.pdf came from a sub directory named ULT00004605.
Does anyone know how to index through the sub directories and put these back where they came from?
The code I used to move them is under "What have I tried?". You can see I used MoveTo when I should've used CopyTo.

What I have tried:

String path = @"S:\QS Storage Server\DHR\ULT\";
 String directoryName = @"G:\SHARED\MoveMe\SNHR_To_Upload\";
            DirectoryInfo dirInfo = new DirectoryInfo(directoryName);
            if (dirInfo.Exists == false)
            {
                Directory.CreateDirectory(directoryName);
            }

            List<String> SNHRFiles = Directory.GetFiles(path, "*.pdf*", SearchOption.AllDirectories).ToList();

            foreach (string file in SNHRFiles)
            {
                FileInfo mFile = new FileInfo(file);
                // to remove name collisions
                if (new FileInfo(dirInfo + "\\" + mFile.Name).Exists == false)
                {
                    mFile.MoveTo(dirInfo + "\\" + mFile.Name);
                }
            }

推荐答案

这很容易解决。您需要做的就是从文件名中获取文件夹名称。请参阅：

It's pretty easy to resolve. All what you need to do is to get folder name from file name. See:

string sFullFileName = @"G:\SHARED\MoveMe\SNHR_To_Upload\ULT00004605_20161105.pdf";
string sDestPathName = @"S:\QS Storage Server\DHR\ULT\";

string sShortFileName = Path.GetFileName(sFullFileName);
string sDestFolderName = sShortFileName.Split(new string[]{"_"}, StringSplitOptions.RemoveEmptyEntries)[0];

Console.WriteLine("File: '{0}' will be copied to: '{1}'", sShortFileName, Path.Combine(sDestPathName, sDestFolderName));

结果：

Result:

File: 'ULT00004605_20161105.pdf' will be copied to: 'S:\QS Storage Server\DHR\ULT\ULT00004605'

由于文件夹已包含我不想删除或不得不移动的其他文件，因此最终解决方案有点比Meciej Los的反应更深入，但他的意见帮助我解决了问题。这是最终的代码。

Since the folders already contained other files that I did not want to delete or have to move, the ultimate solution was a bit more in depth than Meciej Los's response, but his input helped me figure it out. Here is the final code.

String ToPath = @"O:\QS Storage Server\DHR Storage\ULT\";
          String FromPath = @"O:\QS Storage Server\DHR Storage\ULT\SNHR_To_Upload\";

          DirectoryInfo FromdirInfo = new DirectoryInfo(FromPath);
          DirectoryInfo TodirInfo = new DirectoryInfo(ToPath);

          List<String> SNHRFilesToMoveBack = Directory.GetFiles(FromPath, "*.pdf*", SearchOption.AllDirectories).ToList();
          List<String> FoldersForMoveBack = Directory.GetDirectories(ToPath, "*.*", SearchOption.AllDirectories).ToList();

          foreach (string folder in FoldersForMoveBack)
          {
              //search the SNHR_To_Upload folder for the file that matches the folder name
              DirectoryInfo mDirectory = new DirectoryInfo(folder);
              string folderToCopyTo = mDirectory.Name;
              foreach (string file in SNHRFilesToMoveBack)
              {
                  FileInfo mFile = new FileInfo(file);
                  string FileName = Path.GetFileName(file);
                  string ShortName = FileName.Split(new string[] { "_" }, StringSplitOptions.RemoveEmptyEntries)[0];
                  if (folderToCopyTo == ShortName)
                  {
                      try
                      {
                          mFile.MoveTo(mDirectory + "\\" + mFile.Name);
                      }
                      catch (Exception nope)
                      {
                          MessageBox.Show("Cannot Find File" + nope);
                          continue;
                      }
                  }
              }
          }
