There is no built-in method in SharePoint CSOM API for moving
Folder with Files from one location into another.
The following solution demonstrates how to move files from source folder into destination folder:
public static class FolderExtensions
{
public static void MoveFilesTo(this Folder folder, string folderUrl)
{
var ctx = (ClientContext)folder.Context;
if (!ctx.Web.IsPropertyAvailable("ServerRelativeUrl"))
{
ctx.Load(ctx.Web, w => w.ServerRelativeUrl);
}
ctx.Load(folder, f => f.Files, f => f.ServerRelativeUrl, f => f.Folders);
ctx.ExecuteQuery();
//Ensure target folder exists
ctx.Web.EnsureFolder(folderUrl.Replace(ctx.Web.ServerRelativeUrl, string.Empty));
foreach (var file in folder.Files)
{
var targetFileUrl = file.ServerRelativeUrl.Replace(folder.ServerRelativeUrl, folderUrl);
file.MoveTo(targetFileUrl, MoveOperations.Overwrite);
}
ctx.ExecuteQuery();
foreach (var subFolder in folder.Folders)
{
var targetFolderUrl = subFolder.ServerRelativeUrl.Replace(folder.ServerRelativeUrl,folderUrl);
subFolder.MoveFilesTo(targetFolderUrl);
}
}
}
static class WebExtensions
{
/// <summary>
/// Ensures whether the folder exists
/// </summary>
/// <param name="web"></param>
/// <param name="folderUrl"></param>
/// <returns></returns>
public static Folder EnsureFolder(this Web web, string folderUrl)
{
return EnsureFolderInternal(web.RootFolder, folderUrl);
}
private static Folder EnsureFolderInternal(Folder parentFolder, string folderUrl)
{
var ctx = parentFolder.Context;
var folderNames = folderUrl.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
var folderName = folderNames[0];
var folder = parentFolder.Folders.Add(folderName);
ctx.Load(folder);
ctx.ExecuteQuery();
if (folderNames.Length > 1)
{
var subFolderUrl = string.Join("/", folderNames, 1, folderNames.Length - 1);
return EnsureFolderInternal(folder, subFolderUrl);
}
return folder;
}
}
Key points:
- allows to ensure whether destination folder(s) exists
- In case of nested folders, its structure is preserved while moving files
Usage
var srcFolderUrl = "/news/pages";
var destFolderUrl = "/news/archive/pages";
using (var ctx = new ClientContext(url))
{
var sourceFolder = ctx.Web.GetFolderByServerRelativeUrl(srcFolderUrl);
sourceFolder.MoveFilesTo(destFolderUrl);
sourceFolder.DeleteObject(); // delete source folder if nessesary
ctx.ExecuteQuery();
