Check if folder exists in ListItemCollection using "csom" c#

ListItemCollection items = web.Lists.GetByTitle(library).GetItems(query);
                    context.Load(items);
                    context.ExecuteQuery();

now "items"  has N no of folders in it 

is it possible to check whether folder with the name "ABCD" exists in items or not without using foreach or any other loops.
