Question

I have a List that stores items in a folder hierarchy.

I notice that SPFolder.Files.Count is always zero.

Is there a way to find out how many list items are there in a folder?

Answer 1

I presume you are looking for direct children and not descendants (like items within a sub-folder).

Do you also want to include sub-folders in the count? In which case you can use: SPFolder.ItemCount.

If you just want only the direct child listItems which are not subfolders then you can do something like the following:

using (SPSite site = new SPSite(mySPSite))
{
    SPWeb web = site.OpenWeb();
    SPList list = web.Lists[myList];
    SPFolder folderInstance = list.RootFolder.SubFolders[folderUrl];

    SPQuery query = new SPQuery() ;
    query.Folder = folderInstance;

    SPListItemCollection items = list.GetItems(query) ;

    Console.WriteLine(items.Count);
}

I haven’t tried it. You might have to add a where clause to eliminate folders, if the query is returning that.

If you want to include all list-items, even within subfolders, set the SPQuery.ViewAttributes field as query.ViewAttributes = "Scope=\"Recursive\"";
