Linq To Sharepoint–How to do a recursive and folder-scoped query

Hi guys,

I working in a old-style-documents-archive-web-part-implementation that means I have a document library with folders and sub-folder.

I start to say you that I don’t like this solution and I think that use the Managed metada server is a better solution, but anyway if you need to do queries in a document library you have to ways.

If you use SPQuery you need to specify the properties ViewAttributes :

SPQuery query = new SPQuery();
///....
query.ViewAttributes = "Scope=\"RecursiveAll\"";

Instead if you use LinqToSharePoint you can use the property ScopeToFolder:

var q = dc.MyDocs.ScopeToFolder("", true).Where(p => p.DueDate < DateTime.Now.AddMonths(1));

In the MSDN page we can find the following parameters explanation:

public IQueryable<TEntity> ScopeToFolder( string folderUrl, bool recursive )

folderUrl –> The URL of the folder.
recursive –> true to include items in subfolders; false to exclude them.

enjoy
