ASP.NET C# Copy Directory with SubDirectories with System.IO

Question

I need to copy a whole directory C:\\X to C:\\Y\\X, and I need the sub-folders to be copied as well.
Is there any way to do it with the System.IO.File\\Directory namespa

You can use SearchOption.AllDirectories to recursively search down folders, you just need to create the directories before you copy...

// string source, destination; - folder paths 
int pathLen = source.Length;

foreach (string dirPath in Directory.GetDirectories(source, "*", SearchOption.AllDirectories))
{
    string subPath = dirPath.SubString(pathLen);
    string newpath = Path.Combine(destination, subPath);
    Directory.CreateDirectory(newpath );
}

foreach (string filePath in Directory.GetFiles(source, "*.*", SearchOption.AllDirectories))
{
    string subPath = filePath.SubString(pathLen);
    string newpath = Path.Combine(destination, subPath);
    File.Copy(filePath, newpath);
}
