按值列表过滤查询结果

Question

 questionnairs = from q in dbContext.AuditQuestionnaires
                                   .Include("Company")
                                where q.Company != null && q.Company.RecordID == companyId
                                select q;

我使用此查询获得了一些结果集，我在问卷结果集中的整数列表中有一组 id；有一个名为“recordId”的id，基本上我只需要在我的整数列表中存在resultSet的记录id的记录，

我试图做这样的事情，但它失败了

     for (int x = 0; x < RecordIds.Count; x++)

                    {
                        var id = RecordIds[x];
                        questionnairesList = from q in dbContext.AuditQuestionnaires
                                   .Include("Company")
                                        where q.Company != null && q.Company.RecordID == companyId && q.RecordID == id
                                        select q;

                       


                    }

Answer 1

你可以使用包含

questionnairs = from q in dbContext.AuditQuestionnaires
                 .Include("Company")
                  where q.Company != null &&
                        q.Company.RecordID == companyId &&
                        RecordIds.Contains(q.RecordID) == id
                  select q;
