如何将此LINQ查询转换为lambda查询？

public List<Tuple<Klasa2,Klasa2>>CompareLists(List<Klasa2>list1,List<Klasa2>list2)
{
    var pary=
        from l1 in list1
        from l2 in list2
        where l1.tytul.Length<l2.tytul.Length
        select new Tuple<Klasa2,Klasa2>(l1,l2);
    return pary.ToList();
}

这是你在找什么？

public List<Tuple<Klasa2, Klasa2>> CompareLists(List<Klasa2> list1, List<Klasa2> list2)
{
    var pary =
        list1.SelectMany(l1 => list2, (l1, l2) => new {l1, l2})
            .Where(@t => @t.l1.tytul.Length < @t.l2.tytul.Length)
            .Select(@t => new Tuple<Klasa2, Klasa2>(@t.l1, @t.l2));
    return pary.ToList();
}
