CAML query that includes folders in result set

Everyone is close, but not quite right.

using (SPSite site = new SPSite("http://server/site"))
{
  SPWeb web = site.RootWeb; // See disposal guidance http://blogs.msdn.com/b/rogerla/archive/2008/10/04/updated-spsite-rootweb-dispose-guidance.aspx

  SPQuery query = new SPQuery();
  query.Query = @"
          <Where>
            <BeginsWith>
              <FieldRef Name='ContentTypeId' />
              <Value Type='ContentTypeId'>0x0120</Value>
            </BeginsWith>
          </Where>";
  query.ViewAttributes = "Scope='RecursiveAll'";
  SPList list = web.Lists[listId];
  SPListItemCollection items = list.GetItems(query);
  // Do stuff with your folders
}

First of all, using this FieldRef is wrong:

<FieldRef Name='ContentType' /><Value Type='Text'>Folder</Value>

because the folder content type can be inherited. Therefore, you need to compare against the content type ID, like this:

<Where>
  <BeginsWith>
    <FieldRef Name='ContentTypeId' />
    <Value Type='ContentTypeId'>0x0120</Value>
  </BeginsWith>
</Where>

And then, set the view attribute Scope to RecursiveAll

<View Scope='RecursiveAll'>...</View>

That should return any item whose content type inherits from Folder (0x0120)

I don't have my dev image to test against, so I might need to revise this later; but I think you could try

query.ViewAttributes = "Scope=\"Recursive\""; 

Retrieving the items will allow you to use SPUtility.GetUrlDirectory(url) to get the folder path for a given item, and parse the folder hierarchy from there.

You could try basing your caml query on the Folder Content Type instead,

<FieldRef Name='ContentType' /><Value Type='Text'>Folder</Value>

whilst keeping the

Query.ViewAttributes = "Scope=\"RecursiveAll\"";

I've solved this putting:

<QueryOptions>
<IncludeAttachmentUrls>True</IncludeAttachmentUrls>
<Folder/> </QueryOptions>

As query option

I found my question about it on stack overflow:

How can I iterate recursively though a sharepoint list using webservices?

If I remove the other conditions from the query, only leaving the FSObjType=1, I get a COM exception "Cannot complete this action. Please try again."

Did you remove the <Or> tags when you did this? If not it will not run correctly.

Regardless, that does not solve your problem. Have you tried leaving the query empty? Does it return anything?

I have been working on something similar and ran into an issue as well, perhaps it's somewhat related.

This still seems to an issue in SP 2010. Here's workaround code that will work for 2007 or 2010, based on this MSDN Forums post that uses the web services:

private static SPListItem RecurseIntoFolders(SPList list, SPFolder parentFolder, string fileReference)
{
    var query = new SPQuery
    {
        Query = "<Where>" +
                "<Eq><FieldRef Name='FSObjType'/><Value Type='Lookup'>1</Value></Eq>" +
                "</Where>",
        ViewFields = String.Format("<FieldRef Name='{0}' />", FileReferenceInternalFieldName),
        ViewAttributes = "Scope='RecursiveAll'",
        Folder = parentFolder
    };

    var items = list.GetItems(query);
    if (items.Count == 0)
        return null;

    foreach (SPListItem item in items)
    {
        parentFolder = item.Folder;

        // TODO: Any other checking that this is the item we want

        return item;
    }
    return RecurseIntoFolders(list, parentFolder, fileReference);
}

static string GetParentFolder(SPListItem itemToFind, SPFolder folder)  
    { 
        SPQuery query = new SPQuery(); 
       // query.Query =  "<OrderBy><FieldRef Name='Title'/></OrderBy>";
        query.Query = "<Where><Eq><FieldRef Name=\"ID\"/><Value Type=\"Integer\">"+ itemToFind.ID +"</Value></Eq></Where>";
        query.Folder = folder;
        query.ViewAttributes = "Scope=\"Recursive\"";
        SPListItemCollection items = itemToFind.ParentList.GetItems(query);
        int intpartentFolderID=0 ;
        if (items.Count > 0)
        {
        foreach (SPListItem item in items) 
        {

            SPFile f = item.Web.GetFile(item.Url);

            string test11 = f.ParentFolder.Name;
            intpartentFolderID = f.ParentFolder.Item.ID;

            //string test1 = item.File.ParentFolder.Name;

             return (intpartentFolderID.ToString()); 

         }
        }
        return (intpartentFolderID.ToString());     
    }
