File.Copy中的C＃UnauthorizedAccessException

我正在刷新我的C＃，因此我決定編寫一個可用於輕鬆導入我拍攝的照片的程序。一點背景......我用JPEG和RAW拍攝照片，然後瀏覽並選擇JPEG，因爲它們更小，更易於處理/預覽。然後我只導入那些在後期製作中值得搞亂的RAW文件。File.Copy中的C＃UnauthorizedAccessException

我想編寫一個簡單的程序來從一個目錄中複製RAW文件，該目錄與我在另一個目錄中篩選過的JPEG匹配。

下面是代碼：

static void Main(string[] args) 
    { 
     Console.WriteLine("Enter the JPEG Origin Directory: "); 
     string originDirectory = @"C:\Users\Greg\Pictures\Summer 2013\Back Bay\testJPEG"; 

     Console.WriteLine("Enter the RAW Origin Directory: "); 
     string copyDirectory = @"C:\Users\Greg\Pictures\Summer 2013\Back Bay\testRAW"; 

     Console.WriteLine("Enter the RAW Import Directory: "); 
     string rawCopyDirectory = @"C:\Users\Greg\Pictures\Summer 2013\Back Bay\testRAWImport"; 

     char[] delimiterChars = { '_', '.' }; 

     List<string> filesToCopy = new List<string>(); 
     List<string> CopiedFiles = new List<string>(); 

     foreach (var filePath in Directory.GetFiles(originDirectory)) 
     { 
      Console.WriteLine("Filepath: '{0}'", filePath); 
      string[] words = filePath.Split(delimiterChars); 

      filesToCopy.Add(words[1]); 
     } 

     filesToCopy.ForEach(Console.WriteLine); 

     foreach (var copyFilePath in Directory.GetFiles(copyDirectory)) 
     { 
      string[] delimited = copyFilePath.Split(delimiterChars);  

      if (filesToCopy.Contains(delimited[1])) 
      { 
       Console.WriteLine("Copied: '{0}'", copyFilePath); 

       string fileName = Path.GetFileName(copyFilePath); 

       string sourcePath = Path.GetDirectoryName(copyFilePath); 

       string targetPath = rawCopyDirectory; 

       string sourceFile = System.IO.Path.Combine(sourcePath, fileName); 

       string destFile = System.IO.Path.Combine(targetPath, fileName); 


      System.IO.File.Copy(sourcePath, destFile, true); 

      } 


     } 

     Console.WriteLine("Press any key to exit."); 
     Console.ReadKey(); 

    }

一切似乎是工作，當我寫的所有變量到控制檯，我期望，但我得到的Copy.File異常指示文件只讀。我檢查了，但他們不是，但是文件夾本身是，儘管我盡了最大的努力，但我不能將我的測試文件夾作爲只讀文件取消標記。任何幫助將不勝感激，我已經粘貼下面的例外日誌。

Windows資源管理器？ –

是的，這是正確的。 – user2736424

您是否檢查過文件夾屬性的安全權限？ –

您正試圖訪問您的程序可以使用的文件之外的文件。

問題可能是您無法刪除或覆蓋只讀文件。解決方案是更改屬性。

if(File.Exists(destFile)) 
{ 
    File.SetAttributes(destFile, FileAttributes.Normal); 
} 
File.Copy(sourcePath, destFile, true);

原來我調用File.Copy錯誤的變量，而是試圖複製而不是文件（DERP）的路徑。現在一切正常！謝謝你的回覆！
