Answer 1

Haben Sie so etwas wie dies versucht (einige der Kürze halber weggelassen Joins):

var result = from s in TooltipsLanguage 
           join c in TooltipsLanguageSection on s.Id equals c.IdLanguage 
           join p in TooltipsSection on c.IdSection equals p.Id 
           join ... 
           select new MyDestinationObject() 
           { 
            Id = s.BusinessEntityID, 
            Language = s.Language, 
            IdLanguage = c.IdLanguage, 
            ... 
           };
