Copy the entire contents of a directory in C#

Question

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 class

Answer 1

Use this class.

public static class Extensions
{
    public static void CopyTo(this DirectoryInfo source, DirectoryInfo target, bool overwiteFiles = true)
    {
        if (!source.Exists) return;
        if (!target.Exists) target.Create();

        Parallel.ForEach(source.GetDirectories(), (sourceChildDirectory) => 
            CopyTo(sourceChildDirectory, new DirectoryInfo(Path.Combine(target.FullName, sourceChildDirectory.Name))));

        foreach (var sourceFile in source.GetFiles())
            sourceFile.CopyTo(Path.Combine(target.FullName, sourceFile.Name), overwiteFiles);
    }
    public static void CopyTo(this DirectoryInfo source, string target, bool overwiteFiles = true)
    {
        CopyTo(source, new DirectoryInfo(target), overwiteFiles);
    }
}
