How to copy the entire source folder to target folder within same document library using c# and CSOM?

Question

I want to copy the entire source folder to target folder within same document library using c# and CSOM

I've folder structure like in Shared documents/Expenses will be the source folder. the target would be Shared documents/2015/. I've to copy all folders including root folder expenses with files to Shared documents/2015/Expenses

CODE:

public static void CopyFiles(string url, string listTitle, string srcFolder,string destFolder)
    {
    using (var context = new ClientContext(url))
    {
        //context.Credentials = credentials;


        var srcList = context.Web.Lists.GetByTitle(listTitle);
        var qry = CamlQuery.CreateAllItemsQuery();
        qry.FolderServerRelativeUrl = string.Format("{0}", srcFolder);
        var srcItems = srcList.GetItems(qry);
        context.Load(srcItems, icol => icol.Include(i => i.FileSystemObjectType, i => i["FileRef"], i => i.File));
        context.ExecuteQuery();

        foreach (var item in srcItems)
        {
            switch (item.FileSystemObjectType)
            {
                case FileSystemObjectType.Folder:
                    var destFolderUrl = ((string)item["FileRef"]).Replace(srcFolder,destFolder);
                    CreateFolder(context.Web,destFolderUrl);
                    break;
                case FileSystemObjectType.File:
                    var destFileUrl = item.File.ServerRelativeUrl.Replace(srcFolder, destFolder);
                    item.File.CopyTo(destFileUrl, true);
                    context.ExecuteQuery();
                    break;
            }
        }
    }
} 

private static Folder CreateFolder(Web web, string folderUrl)
{
    if (string.IsNullOrEmpty(folderUrl))
        throw new ArgumentNullException("Folder Url could not be empty");

    var folder = web.Folders.Add(folderUrl);
    web.Context.Load(folder);
    web.Context.ExecuteQuery();
    return folder;
}`

But it is not copying the root folder. Instead it is copying all folders and files inside root folder. Can someone help what I'm missing in this ?

You can try out this way:

public bool PasteFolder(string url, string source, string sourceListName, string target, string targetListName, string targetFolderName, string token)
    {
        bool isFolderPasted = false;
        try
        {
            using (var context = new ClientContext(url))
            {
                //context.Credentials = credentials;     
                var currentWeb = context.Site.OpenWeb(url);
                var addFoldername = targetFolderName;
                var sourceFolder = currentWeb.GetFolderByServerRelativeUrl(source);
                context.Load(sourceFolder.Folders);
                context.Load(sourceFolder.Files);
                context.ExecuteQuery();
                Folder newfolder;

                try
                {
                    newfolder = currentWeb.GetFolderByServerRelativeUrl(target);
                    context.Load(newfolder);
                    context.ExecuteQuery();
                }
                catch
                {
                    target = target.Replace("/", string.Empty).Trim();
                    var list = currentWeb.Lists.GetByTitle(target);
                    newfolder = list.RootFolder;
                    context.Load(newfolder);
                    context.ExecuteQuery();
                }

                var currentFolder = newfolder.Folders.Add(addFoldername);
                context.Load(currentFolder);
                context.Load(currentFolder.Folders);
                context.Load(currentFolder.Files);
                context.ExecuteQuery();

                foreach (var file in sourceFolder.Files)
                {
                    file.CopyTo(currentFolder.ServerRelativeUrl + "/" + file.Name, true);
                    context.ExecuteQuery();
                }
                foreach (var cFolder in sourceFolder.Folders)
                {
                    PasteFolder(url, cFolder.ServerRelativeUrl, sourceListName, currentFolder.ServerRelativeUrl, targetListName, cFolder.Name, token);
                }
                isFolderPasted = true;
            }
        }
        catch (Exception ex)
        {
        }
        return isFolderPasted;
    }
