如何在以下LINQ to SQL Query中编写“Where”子句？

Question

我正在处理以下LINQ查询：

public void GetAuditRuleAgencyRecords(IEnumerable<Entities.AuditRule> rules)
{
    using (LinqModelDataContext db = new LinqModelDataContext())
    {
        var auditAgencyRecords = (from ag in db.Agencies
                        join ara in db.AuditRuleAccounts on ag.Agency_Id equals ara.AgencyID
                        join arr in db.AuditRuleResults on ara.AuditRuleAccountID equals arr.AuditRuleAccountID
                        join are in db.AuditRuleEnterprises on arr.AuditRuleEnterpriseID equals are.AuditRuleEnterpriseID
                        select new
                        {

                            AgencyID = ag.Agency_Id,
                            AgencyName = ag.Agency_Name,
                            AuditRuleEnterpriseID = arr.AuditRuleEnterpriseID,
                            CorrectedDate = arr.CorrectedDate,
                            NbrDaysToCorrect = arr.NbrDaysToCorrect,      

                        }).ToList();
    }
}

你可以看到我传入了IEnumerable规则。 我传入的每个AuditRule对象都有一个名为“ID”的属性。

如果我想说的话，我的where子句对于这个查询会是什么样子，只返回表列AuditRuleEnterprise.AuditID匹配我的规则“ID”属性中的任何一个ID的记录（我传递给方法的对象） ）？

尝试：

.Where(rules.Select(r => r.ID).Contains(arr.AuditRuleEnterpriseID.AuditID))

或者，在查询语法中

where rules.Select(r => r.ID).Contains(arr.AuditRuleEnterpriseID.AuditID)
