删除目录而不是其中的文件

Deletes a directory instead of the files inside it

问题

在存储库文件夹内处理文件和目录时存在问题。问题在于，当您尝试仅删除特定文件夹内的文件时，“UploadedFilesForEncrypting”文件夹本身也被删除。

这是用于用户共享文件夹的字段：

  1. public string FolderForEnc
  2. {
  3.     get
  4.     {
  5.         return Path.Join(_webHostEnvironment.WebRootPath, "UploadedFilesForEncrypting");
  6.     }
  7. }

这是控制器本身，其中包含删除用户文件夹中文件的一些逻辑：

  1. [HttpDelete("DeleteEncryptedFiles")]
  2. public IActionResult DeleteFiles([FromHeader(Name = "ApiKey")] string apiKey)
  3. {
  4.     try
  5.     {
  6.         // 在这里进行 API 密钥的验证和用户授权
  7.         var userid = "air"; //_readUser.ReadUserIdByApiKey(apiKey)
  8.         string uploadsFolder = Path.Join(FolderForEnc, $"User({userid})");
  10.         if (Directory.Exists(uploadsFolder))
  11.         {
  12.             string[] uploadedFiles = Directory.GetFiles(uploadsFolder);
  13.             if (uploadedFiles.Length > 0)
  14.             {
  15.                 foreach (string filePath in uploadedFiles)
  16.                 {
  17.                     System.IO.File.Delete(filePath);
  18.                 }
  20.                 return Ok(new { message = "文件删除成功" });
  21.             }
  23.             return NotFound("您的文件夹中没有文件");
  24.         }
  25.         else
  26.         {
  27.             return NotFound("用户文件夹未找到");
  28.         }
  29.     }
  30.     catch (InvalidOperationException)
  31.     {
  32.         return BadRequest("未找到具有此 API 密钥的用户");
  33.     }
  34.     catch (Exception ex)
  35.     {
  36.         return BadRequest(ex.Message);
  37.     }
  38. }

尝试更改Path.Join为Path.Combine，尝试将Directory.GetFiles(uploadsFolder)更改为Directory.GetFiles(uploadsFolder, "*", SearchOption.AllDirectories)。我还尝试删除参数，并像这个示例中传递抽象数据，但没有帮助。

英文:

There is a problem with working with files and directories inside the repository folder. The problem is that when you try to delete only files inside a certain folder, the "UploadedFilesForEncrypting" folder itself is deleted.

Here is the field with shared folder for users

  1. public string FolderForEnc
  2. {
  3.     get
  4.     {
  5.         return Path.Join(_webHostEnvironment.WebRootPath, "UploadedFilesForEncrypting");
  6.     }
  7. }

Here is the controller itself in which there is a small logic for deleting files in the user folder

  1.     [HttpDelete("DeleteEncryptedFiles")]
  2.     public IActionResult DeleteFiles([FromHeader(Name = "ApiKey")] string apiKey)
  3.     {
  4.         try
  5.         {
  6.             // ЗДЕСЬ ПРОВЕРКА ПОДДЛИННОСТИ API КЛЮЧА И АВТОРИЗАЦИЯ ПОЛЬЗОВАТЕЛЯ
  7.             var userid = "air"; //_readUser.ReadUserIdByApiKey(apiKey)
  8.             string uploadsFolder = Path.Join(FolderForEnc, $"User({userid})");
  10.             if (Directory.Exists(uploadsFolder))
  11.             {
  12.                 string[] uploadedFiles = Directory.GetFiles(uploadsFolder);
  13.                 if(uploadedFiles.Length > 0)
  14.                 {
  15.                     foreach (string filePath in uploadedFiles)
  16.                     {
  17.                         System.IO.File.Delete(filePath);
  18.                     }
  20.                     return Ok(new { message = "Files deleted successfully" });
  21.                 }
  23.                 return NotFound("There are no files in your folder");
  24.             }
  25.             else
  26.             {
  27.                 return NotFound("User folder not found");
  28.             }
  29.         }
  30.         catch (InvalidOperationException)
  31.         {
  32.             return BadRequest("User with this API key not found");
  33.         }
  34.         catch (Exception ex)
  35.         {
  36.             return BadRequest(ex.Message);
  37.         }
  38.     }

Tried changing Path.Join to Path.Combine, tried changing Directory.GetFiles(uploadsFolder) to Directory.GetFiles(uploadsFolder, "*", SearchOption.AllDirectories). I also tried to remove parameters and pass abstract data as in this example.
None of this helped.

结果是什么，有没有错误？据我所知，File.Delete 如果文件不存在是不会抛出任何错误的。

  • 如果您确定路径正确，请检查文件夹的权限以执行删除操作。
  • 请确保您输入的文件扩展名是正确的。
  • 最后一种可能是文件仍然被某个后台进程使用。在这种情况下，它不会失败，但也不会删除文件。
英文:

What is the result, is there any error? As I know, File.Delete does not throw any error if file is not exists.

  • If you are certain about the path, please check folder's permission
    to delete operations.
  • Please ensure that the file extensions are correct which you put.
  • Last option is that the file is still in use by some background
    process. Then it does not fail but it does not delete the file.
