多加入实体框架

Question

我在TSQL以下查询

select * from users 
inner join linkUserPhoneNumber on users.UserId = linkUserPhoneNumber.UserId 
INNER JOIN PhoneNumber ON PhoneNumber.PhoneNumberId = 
    linkUserPhoneNumber.PhoneNumberId 
    where UserName = 'superuser' and password ='password' 

我在实体框架下面的查询

var query = (from u in myEntities.Users 
    join link in myEntities.linkUserPhoneNumbers on u.UserId equals link.UserId 
    join p in myEntities.PhoneNumbers on p.PhoneNumberId equals link.PhoneNumberId 
    where u.UserName == Username && u.Password == Password 
    select u).ToList(); 

当我尝试编译它，我得到

错误3名称'p'不在'等于'左侧的范围内。考虑交换'equals'两边的表达式。
错误4名称'链接'不在'等于'右侧的范围内。考虑交换'equals'两边的表达式。

Answer 1

p.PhoneNumberId equals link.PhoneNumberId 

应该是究竟是什么错误是说

link.PhoneNumberId equals p.PhoneNumberId 

的完整代码

var query = (from u in myEntities.Users 
    join link in myEntities.linkUserPhoneNumbers on u.UserId equals link.UserId 
    join p in myEntities.PhoneNumbers on link.PhoneNumberId equals p.PhoneNumberId 
    where u.UserName == Username && u.Password == Password 
    select u).ToList();
