Question

How do I copy a directory to a different drive in C#?

Answer 1

You can use this code to perform your operation:

public static  void CopyAll(DirectoryInfo source, DirectoryInfo target)
{
    // Check if the target directory exists, if not, create it.
    if (Directory.Exists(target.FullName) == false)
    {
        Directory.CreateDirectory(target.FullName);
    }

    // Copy each file into it’s new directory.
    foreach (FileInfo fi in source.GetFiles())
    {
        Console.WriteLine(@”Copying {0}\{1}”, target.FullName, fi.Name);
        fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
    }

    // Copy each subdirectory using recursion.
    foreach (DirectoryInfo diSourceSubDir in source.GetDirectories())
    {
        DirectoryInfo nextTargetSubDir =
            target.CreateSubdirectory(diSourceSubDir.Name);
        CopyAll(diSourceSubDir, nextTargetSubDir);
    }
}

below one is also good:

    static public void CopyFolder( string sourceFolder, string destFolder )
    {
        if (!Directory.Exists( destFolder ))
            Directory.CreateDirectory( destFolder );
        string[] files = Directory.GetFiles( sourceFolder );
        foreach (string file in files)
        {
            string name = Path.GetFileName( file );
            string dest = Path.Combine( destFolder, name );
            File.Copy( file, dest );
        }
        string[] folders = Directory.GetDirectories( sourceFolder );
        foreach (string folder in folders)
        {
           string name = Path.GetFileName( folder );
           string dest = Path.Combine( destFolder, name );
            CopyFolder( folder, dest );
        }
    }

you can use this function also:

FileSystem.CopyDirectory(sourceDir, destDir);
