More questions on finding subdirectories in C #

Question

I recently asked a question about finding directories in C # .

Program logic

• List all directories in a line or several lines.
• Try copying the file using the line.
  • If this fails, continue to the next line,
• If you can find the file:
  • Copy
  • go to next record in text file

Final result

If he finds it on the 4th line, he will not try the next 15 lines.

Code snippet

 if (checkBox2.Checked)
        {
            string[] file_names = File.ReadAllLines(@"c:\dact.txt");
            string path1 = @"I:\pa\test\";
            string path2 = @"I:\pa\test2\";
            string path3 = @"I:\pa\test3\";
            string path4 = @"I:\pa\test4\";

            string full = (string.Concat(path1, file_names, ".txt"));
            foreach (string file_name in file_names)
            if (System.IO.File.Exists(full))
            {
                foreach (string file in file_names)
                System.IO.File.Copy(file, 
                                    @"C:\" + 
                                    textBox1.Text + 
                                    @"\\OC\" + 
                                    file_name + ".txt");
            }
        }

The above code does not contain the ability to write files with an error, I'm not sure how to do this.

Answer 1

:

String[] filesToCopy = File.ReadAllLines("yourFileHere.txt");

String sourceFolder = "yourSourceFolderHere";
String destinationFolder = "yourDestinationFolderHere";

foreach (String subFolder in Directory.GetDirectories(sourceFolder))
{
    for (int i = 0; i < filesToCopy.Length; i++)
    {
        if (!String.IsNullOrEmpty(filesToCopy[i]))
        {
        if (File.Exists(Path.Combine(subFolder, filesToCopy[i])))
        {
            File.Copy(Path.Combine(subFolder, filesToCopy[i]), Path.Combine(destinationFolder, FilesToCopy[i]));
            filesToCopy[i] = string.Empty;
        }
        }
    }
}

using (StreamWriter strm = new StreamWriter("yourOutputFile.txt"))
{
    foreach (String fileToCopy in filesToCopy)
    {
        if (!String.IsNullOrEmpty(fileToCopy))
        strm.WriteLine(fileToCopy);
    }
}
