Samples of use

Simple

       //Select all items in system search an get a projection of unknown type with the following properties: 
         //                string ItemName, string Author, string[] Kind, Music Music, string language

          SystemIndex<SystemSearch> si = new SystemIndex<SystemSearch>();
         
            var result = (from SystemSearch t in si
                             select new { t.ItemName, t.Author, t.Kind, t.Music, t.Language });

Using WHERE

         //Select all folders or documents where ItemName contains "esk"

           SystemIndex<SystemSearch> si = new SystemIndex<SystemSearch>();
         
            var result = (from SystemSearch t in si
                                 where (t.Kind == new string[] { "document" } ||  t.Kind == new string[] { "Folder" }  )  &&  t.ItemName.Contains("esk")
                                 select new { t.ItemName, t.Author, t.Kind, t.Music, t.Language });

Using Order By

         //Select all folders or documents where ItemName contains "esk" ordered by Kind

           SystemIndex<SystemSearch> si = new SystemIndex<SystemSearch>();
         
            var result =   (from SystemSearch t in si
                                 where (t.Kind == new string[] { "document" } ||  t.Kind == new string[] { "Folder" }  )  &&  t.ItemName.Contains("esk")
                                 orderby t.Kind
                                 select new { t.ItemName, t.Author, t.Kind, t.Music, t.Language });
