What is the best way to recursively copy a folder's content into another folder using C# and ASP.NET?

+9  A: 

Well you can try this

    DirectoryInfo sourcedinfo = new DirectoryInfo(@"E:\source");
    DirectoryInfo destinfo = new DirectoryInfo(@"E:\destination");
    copy.CopyAll(sourcedinfo ,destinfo);

and this is the method that do all the work:

public void CopyAll(DirectoryInfo source, DirectoryInfo target)
        {
            try
            {
                //check if the target directory exists
                if (Directory.Exists(target.FullName) == false)
                {
                    Directory.CreateDirectory(target.FullName);
                }

                //copy all the files into the new directory

                foreach (FileInfo fi in source.GetFiles())
                {
                    fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
                }


                //copy all the sub directories using recursion

                foreach (DirectoryInfo diSourceDir in source.GetDirectories())
                {
                    DirectoryInfo nextTargetDir = target.CreateSubdirectory(diSourceDir.Name);
                    CopyAll(diSourceDir, nextTargetDir);
                }
                //success here
            }
            catch (IOException ie)
            {
       //hundle it here
            }
        }

I hope this will help :)

Great code there is one thing i would change: //check if the target directory exists if (Directory.Exists(target.FullName) == false) { Directory.CreateDirectory(target.FullName); }you can just you the DirectoryInfo object you already have: if (!target.Exists) { target.Create(); }

Just use Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory in Microsoft.VisualBasic.dll assembly.

Add a reference to Microsoft.VisualBasic

Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory(source, destination);
