Creating Nested Folders via Client Object Model

Question

I'm trying to create nested folders in my document library so it looks like this:

http://site/PublicDocuments/Folder1/Folder2/Folder3/

The document library "Public Documents" exists but none of the folders exist yet.

Here's the working code for those interested:

 ClientContext clientContext = new ClientContext(url); Web web = clientContext.Web; var query = clientContext.LoadQuery(web.Lists.Where(p => p.Title == "Public Documents")); clientContext.ExecuteQuery(); List list = query.FirstOrDefault(); var folder = list.RootFolder; clientContext.Load(folder); clientContext.ExecuteQuery(); string[] namesArray = new string[] { "/Folder1", "Folder2", "Folder3" }; foreach(string name in namesArray) { folder = folder.Folders.Add(name); } clientContext.ExecuteQuery();

Thanks!

Try not calling clientContext.Load, for example this works for me:

var folder = list.RootFolder; clientContext.Load(folder); clientContext.ExecuteQuery(); folder = folder.Folders.Add("Folder 1"); folder.Folders.Add("Folder 2"); clientContext.ExecuteQuery();

Thanks, that works. I'm going to post the code using the foreach loop shortly — ATAI

How to create Folder (including nested) via CSOM in SharePoint

/// <summary> /// Create Folder (including nested) client object /// </summary> /// <param name="web"></param> /// <param name="listTitle"></param> /// <param name="fullFolderPath"></param> /// <returns></returns> public static Folder CreateFolder(Web web, string listTitle, string fullFolderPath) { if (string.IsNullOrEmpty(fullFolderPath)) throw new ArgumentNullException("fullFolderPath"); var list = web.Lists.GetByTitle(listTitle); return CreateFolderInternal(web, list.RootFolder, fullFolderPath); } private static Folder CreateFolderInternal(Web web, Folder parentFolder, string fullFolderPath) { var folderUrls = fullFolderPath.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries); string folderUrl = folderUrls[0]; var curFolder = parentFolder.Folders.Add(folderUrl); web.Context.Load(curFolder); web.Context.ExecuteQuery(); if (folderUrls.Length > 1) { var folderPath = string.Join("/", folderUrls, 1, folderUrls.Length - 1); return CreateFolderInternal(web, curFolder, folderPath); } return curFolder; }

Usage

 using (var ctx = new ClientContext("https://contoso.intranet.com/")) { var folder = CreateFolder(ctx.Web, "Shared Documents", "FolderA/SubFolderA/SubSubFolderA"); }

Thank you for this answer. I was wondering if you could check if one or more folder in the nested path already exists and if so skip that. — Animesh D

How about something like this:

 public static Folder EnsureFolder(ClientContext ctx, Folder ParentFolder, string FolderPath) { //Split up the incoming path so we have the first element as the a new sub-folder name //and add it to ParentFolder folders collection string[] PathElements = FolderPath.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries); string Head = PathElements[0]; Folder NewFolder = ParentFolder.Folders.Add(Head); ctx.Load(NewFolder); ctx.ExecuteQuery(); //If we have subfolders to create then the length of PathElements will be greater than 1 if (PathElements.Length > 1) { //If we have more nested folders to create then reassemble the folder path using what we have left i.e. the tail string Tail = string.Empty; for (int i = 1; i < PathElements.Length; i++) Tail = Tail + "/" + PathElements[i]; //Then make a recursive call to create the next subfolder return EnsureFolder(ctx, NewFolder, Tail); } else //This ensures that the folder at the end of the chain gets returned return NewFolder; }

and then you can call it with following:

ctx.Load(TargetList.RootFolder); ctx.ExecuteQuery(); Folder NewFolder = EnsureFolder(ctx, TargetList.RootFolder, "/Folder1/Folder2/Folder3");

var list = ctx.GetListByTitle("MyList); list.EnableFolderCreation = true; list.RootFolder.EnsureFolder("NewFolder1").EnsureFolder("NewSubFolderToFolder1"); ctx.ExecuteQuery();

Try looping through and adding each folder and then call ExecuteQuery

 string[] namesArray = new string[] { "Folder1","Folder2"}; foreach (string name in namesArray) { //Add Folder var folders = list.RootFolder.Folders; clientContext.Load(folders); clientContext.ExecuteQuery(); var newFolder = folders.Add(name); } //Execute request clientContext.ExecuteQuery();

That code is from the example I was trying to follow. That will only create folders at the root level, resulting in: site/PublicDocuments/Folder1 site/PublicDocuments/Folder2 which is not what I'm looking for — ATAI

Use the below simple code.

 public void CreateFolder(string url, string foldername,string documentlibname) { try { ClientContext clientContext = new ClientContext(url); Web web = clientContext.Web; var query = clientContext.LoadQuery(web.Lists.Where(p => p.Title == documentlibname));## Heading ## clientContext.ExecuteQuery(); List list = query.FirstOrDefault(); var folder = list.RootFolder; clientContext.Load(folder); clientContext.ExecuteQuery(); string[] PathElements = foldername.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries); for (int i = 0; i < PathElements.Length; i++) { folder = folder.Folders.Add(PathElements[i].ToString()); clientContext.ExecuteQuery(); } //folder = folder.Folders.Add(foldername); //clientContext.ExecuteQuery(); } catch (System.Exception ex) { throw; } }
