C# – Copy the entire contents of a directory in C#

ccopydirectorynet

I want to copy the entire contents of a directory from one location to another in C#.

There doesn't appear to be a way to do this using System.IO classes without lots of recursion.

There is a method in VB that we can use if we add a reference to Microsoft.VisualBasic:

new Microsoft.VisualBasic.Devices.Computer().
    FileSystem.CopyDirectory( sourceFolder, outputFolder );

This seems like a rather ugly hack. Is there a better way?

Much easier

private static void CopyFilesRecursively(string sourcePath, string targetPath)
{
    //Now Create all of the directories
    foreach (string dirPath in Directory.GetDirectories(sourcePath, "*", SearchOption.AllDirectories))
    {
        Directory.CreateDirectory(dirPath.Replace(sourcePath, targetPath));
    }

    //Copy all the files & Replaces any files with the same name
    foreach (string newPath in Directory.GetFiles(sourcePath, "*.*",SearchOption.AllDirectories))
    {
        File.Copy(newPath, newPath.Replace(sourcePath, targetPath), true);
    }
}
