Answer 1

试试这个

var result = db.PersonRank(i => new
                        {
                            PersonRank = i.PersonRank,
                            amount = i.amount,
                            PersonRankSum = (db.PersonRank
                                              .Where(t => t.PersonRank <= i.PersonRank)
                                              .Sum(t => t.Amount)
                                             )

                        }).OrderBy(i => i.PersonRank);

Answer 2

var query = 
    from pr in context.PersonRanks
    orderby pr.PersonRank
    select new 
        { 
            pr.PersonRank, 
            pr.Amount, 
            Sum = context.PersonRanks.Where(p => p.PersonRank <= pr.PersonRank).Sum(p => p.Amount)
        };
