C# UnauthorizedAccessException in File.Copy

Question

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.

Answer 1

Turns out I was calling the wrong variable in File.Copy, and instead was trying to copy a path instead of a file (derp). Everything works now! Thanks for the replies!

Answer 2

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

Try looking at this older post Why is access to the path denied?

Answer 3

The problem can be that you can not delete or overwrite read-only files. The solution is to change the attributes.

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