在File.Copy C＃UnauthorizedAccessException [英] C# UnauthorizedAccessException in File.Copy

问题描述

我在我的C＃刷牙，所以我决定写一个程序，我可以用它来轻松地导入我拍照。一点背景...我在拍摄JPEG和RAW照片，然后再通过并选择通过JPEG文件，因为它们是更小，更容易处理/预览。然后，我只导入是值得在后期制作那些搞乱RAW文件。

我想写一个简单的程序复制从一个目录RAW文件相匹配，我已经在另一个通过筛选的JPEG格式的。

下面是代码：

 静态无效的主要（字符串[ ]参数）
 {
 Console.WriteLine（请输入JPEG产地目录：）; 
串originDirectory = @C：\Users\Greg\Pictures\Summer 2013\Back Bay\testJPEG 
 
 Console.WriteLine（请输入原始产地目录：）; 
串copyDirectory = @C：\Users\Greg\Pictures\Summer 2013\Back Bay\testRAW 
 
 Console.WriteLine（请输入原始导入目录：）; 
串rawCopyDirectory = @C：\Users\Greg\Pictures\Summer 2013\Back Bay\testRAWImport 
 
的char [] delimiterChars = {'_'，'。'}; 
 
名单，LT;字符串> filesToCopy =新的List<串GT;（）; 
名单，LT;字符串> CopiedFiles =新的List<串GT;（）; 
 
的foreach（在Directory.GetFiles VAR文件路径（originDirectory））
 {
 Console.WriteLine（文件路径：{0}'，文件路径）; 
的String []字= filePath.Split（delimiterChars）; 
 
 filesToCopy.Add（字[1]）; 
} 
 
 filesToCopy.ForEach（Console.WriteLine）; 
 
的foreach（在Directory.GetFiles VAR copyFilePath（copyDirectory））
 {
的String []分隔= copyFilePath.Split（delimiterChars）; 
 
如果（filesToCopy.Contains（分隔[1]））
 {
 Console.WriteLine（复制：{0}'，copyFilePath）; 
 
字符串文件名= Path.GetFileName（copyFilePath）; 
 
串SOURCEPATH = Path.GetDirectoryName（copyFilePath）; 
 
串TARGETPATH = rawCopyDirectory; 
 
串的SourceFile = System.IO.Path.Combine（SOURCEPATH，文件名）; 
 
串destFile = System.IO.Path.Combine（TARGETPATH，文件名）; 
 
 
 System.IO.File.Copy（SOURCEPATH，destFile，真正的）; 
 
} 
 
 
} 
 
 Console.WriteLine（按任意键退出。）; 
 Console.ReadKey（）; 
 
} 
  

一切似乎是工作，我期望我的时候所有的变量写入到控制台，但是我得到的 Copy.File 的异常，表示文件是只读的。我查了一下，他们都没有，但是该文件夹本身，尽管我尽了最大努力，我不能取消标记我的测试文件夹为只读。任何帮助，将不胜感激，我已经粘贴下面的异常日志。

解决方案

您试图访问你的程序可以使用什么样之外的文件。

尝试寻找这个较早的帖子 System.UnauthorizedAccessException：对被拒绝的路径

I am brushing up on my C# so I decided to write a program that I can use to easily import photos that I take. A little background...I shoot photos in JPEG and RAW and then go through and pick through the JPEGs since they are smaller and easier to handle/preview. I then import only those RAW files that are worth messing with in post production.

I wanted to write a simple program to copy the RAW files from one directory that match the JPEGs that I've sifted through in another.

Here is the code:

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();

    }

Everything seems to be working as I'd expect when I write all the variables to the console, however I'm getting an exception on Copy.File that indicates the files are read only. I checked, and they aren't, however the folder itself is, and despite my best efforts I cannot unflag my test folders as readonly. Any help would be appreciated, I've pasted the exception log below.

You are trying to access a file outside of what your program can use.
