如何从C＃中的openFileDialog复制选定的文件夹，子文件夹和文件

Question

I have a function that is suposed to copy all folders, subfolders files selected from openFileDialog from a location to another:

I've made this function to copy all the selected paths:

 public void CopiarFicheiros(string CopyTo, List<string> FilesToCopy )
        {

            foreach (var item in FilesToCopy)
            {
                string DirectoryName = Path.GetDirectoryName(item);
                string Copy = Path.Combine(CopyTo, DirectoryName);
                if (Directory.Exists(Copy) && DirectoryName.ToLower() != "newclient" && DirectoryName.ToLower() != "newservice")
                {
                    Directory.CreateDirectory(Copy);
                    File.Copy(item, Copy + @"\" + Path.GetFileName(item), true);
                }
                else File.Copy(item, CopyTo + @"\" + Path.GetFileName(item), true);
            }

        }

The logic is full of flaws and I'm running out of time and can't seem to find a proper solution to this.

This is how I get the selected files and folders from the dialog:

  private List<string> GetFiles()
        {
            var Files = new List<string>();
            if (openFileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                string sFileName = openFileDialog.FileName;
                string[] arrAllFiles = openFileDialog.FileNames;
                Files = arrAllFiles.ToList();
            }
            return Files;
        }

Does anyone have a better solution or a clue to what I need to change to successfully do this? Any help is highly appreciated, thank you

Don't use OpenFileDialog to choose the folder. As the name suggests, it not made for that task. You want the FolderBrowserDialog class for this task.

How to: Copy Directories :

// Copy from the current directory, include subdirectories.
DirectoryCopy(".", @".\temp", true);

---

private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
    // Get the subdirectories for the specified directory.
    DirectoryInfo dir = new DirectoryInfo(sourceDirName);

    if (!dir.Exists)
    {
        throw new DirectoryNotFoundException(
            "Source directory does not exist or could not be found: "
            + sourceDirName);
    }

    DirectoryInfo[] dirs = dir.GetDirectories();
    // If the destination directory doesn't exist, create it.
    if (!Directory.Exists(destDirName))
    {
        Directory.CreateDirectory(destDirName);
    }

    // Get the files in the directory and copy them to the new location.
    FileInfo[] files = dir.GetFiles();
    foreach (FileInfo file in files)
    {
        string temppath = Path.Combine(destDirName, file.Name);
        file.CopyTo(temppath, false);
    }

    // If copying subdirectories, copy them and their contents to new location.
    if (copySubDirs)
    {
        foreach (DirectoryInfo subdir in dirs)
        {
            string temppath = Path.Combine(destDirName, subdir.Name);
            DirectoryCopy(subdir.FullName, temppath, copySubDirs);
        }
    }
}
