Linq中的in和not in的使用方法

T-SQL语句：

select * from PayingRecords where ClientID='17787665-1d98-49e6-b254-a6a6553c4b42'
and  ID not in
    (select PayingRecordID from InvoicingRecordDetails where InvoicingRecordID in 
        (    
         select ID from InvoicingRecords where 
         ClientID='17787665-1d98-49e6-b254-a6a6553c4b42'
         )
     )

Linq语句：

 var query = from p in db.PayingRecords
                             where !(from i in db.InvoicingRecordDetails 
                                     where (from ii in db.InvoicingRecords

                                            select ii.ID).Contains(i.InvoicingRecordID)
                                     select i.PayingRecordID
                                     ).Contains(p.ID)
                             //join td1 in db.DataAuthorities on p.DataAuthorityID equals td1.ID into p_td1
                             //from pp in p_td1.DefaultIfEmpty()
                             //join c in db.Clients on p.ClientID equals c.ID into c_join
                             //from tmp in c_join.DefaultIfEmpty()

                               //  DataAuthorityValue = pp.Value,
                                 ClusterID = p.ClusterID,
                                 ArrivingAmount = p.ArrivingAmount,
                                 ClientID = p.ClientID,
                               //  ClientName = tmp.Name,
                                 ArrivingTime = p.ArrivingTime,

                                 UpdateTime = p.UpdateTime,
                                 UpdateUser = p.UpdateUser,
                                 CreateTime = p.CreateTime,

Linq生成的语句：
