的nHibernate QueryOver <T>并发症

Question

我有以下表：

客户=> CustomerAccount =>帐户

我有一个的nHibernate映射到POCO每个表的以上为好。

我有一个实现IIdentifier<T>

public Expression<Func<ICustomer, bool>> Filter 
{ 
    get { return customer => customer.CustomerNumber == _customerNumber; } 
} 

现在我想要做的是通过QueryOver<Account>

加入客户=> CustomerAccount =>帐户表对象以下lambda表达式如何我是否添加上面的Filter lamdba（客户类型）以按客户编号进行过滤？

ICustomer customer = null; 
ICustomerAccount customerAccount = null; 
IAccount account = null; 

var query = QueryOver(() => account) 
    .JoinAlias(() => account.CustomerAccounts,() => customerAccount, JoinType.InnerJoin) 
    .JoinAlias(() => customerAccount.Customer,() => customer, JoinType.InnerJoin) 
    .Where(() => customerAccount.EndDate == null) 
    .And(() => account.IsPreferredAccount == true) 
    .And(() => ?? Want to add the above Filter() lambda some how here); 

感谢，

Answer 1

你可以尝试：

var query = QueryOver(() => account) 
    .JoinAlias(() => account.CustomerAccounts,() => customerAccount, JoinType.InnerJoin) 
    .JoinAlias(() => customerAccount.Customer,() => customer, JoinType.InnerJoin) 
    .Where(() => customerAccount.EndDate == null) 
    .And(() => account.IsPreferredAccount == true) 
    .And(Restrictions.Where<ICustomer>(Filter));
