FileUpload C# - Upload entire folder

Question

_{Thursday, February 23, 2012 3:19 PM}

Hey guys.

Is there any way I can upload one entire folder with FileUpload in C#

When I'm trying to upload, it only allows me to upload files, not folders. Is there any way I can do this?

Simply create a folder on the target drive (if needed) and upload all the files in a folder to it... You could always wrap the process in a method called DirectoryUpload. Alternatively, if you want to do a proper job, you would use a recursive method similar to this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace CopyDirectoryTree
{
    class Program
    {
        static void Main(string[] args)
        {
            CopyDirectoryStructure(@"C:\Documents and Settings\James\Desktop\TestFrom",
                @"C:\Documents and Settings\James\Desktop\TestTo", true);
        }
        private static void CopyDirectoryStructure(string SourcePath, string DestinationPath, bool overwriteexisting)
        {
            try
            {
                SourcePath = SourcePath.EndsWith(@"\") ? SourcePath : SourcePath + @"\";
                DestinationPath = 
                    DestinationPath.EndsWith(@"\") ? DestinationPath : DestinationPath + @"\";

                if (Directory.Exists(SourcePath))
                {
                    if (Directory.Exists(DestinationPath) == false)
                        Directory.CreateDirectory(DestinationPath);

                    foreach (string fls in Directory.GetFiles(SourcePath))
                    {
                        FileInfo flinfo = new FileInfo(fls);
                        flinfo.CopyTo(DestinationPath + flinfo.Name, overwriteexisting);
                    }
                    foreach (string drs in Directory.GetDirectories(SourcePath))
                    {
                        DirectoryInfo diDi = new DirectoryInfo(drs);
                        CopyDirectoryStructure(drs, DestinationPath + diDi.Name, overwriteexisting);
                    }
                }
            }
            catch (Exception ex)
            {
            }
        }
    }
}

Replace the lines where files are copied with your code to upload a file to the server and just change the names to thing that make sense to you. (And of course remove all the irrelevant lines - the code is just to illutrate using recursion to copy full directories and their subfolders). And add some proper exception handling. :)

String path = Server.MapPath("~/Uploads/" + "somename"); //somename is the name of the folder
        if (Directory.Exists(path))
        {
            Directory.CreateDirectory(path);
        }
        DirectoryInfo di;
        di = new DirectoryInfo("C:/KA/KG"); // source folder
        foreach (FileInfo f in di.GetFiles())
        {
            f.CopyTo(path + "/" + f.Name); //files get copied in the Web Server path with the same folder and the files in it.
        }

Simply create the folder with the same name as you want for your folder and then copy the files recursively.
