将sql查询转换为linq

Question

我有这个SQL查询：

select RoleID 
 from tblUserRole
 where UserID = 1
   and RoleID in 
       (Select ID from tblGreenRole 
        Where 
        IsFullAccess = 1) 

如何将此查询转换为linq？

Answer 1

这样的事情：

 var result = (from t1 in context.tblUserRole
 join t2 in context.tblGreenRole on t1.RoleID equals t2.ID
 where t1.UserID == 1 && t2.IsFullAccess == 1).ToList();

如果IsFullAccess的类型为bit，则更改为&& t2.IsFullAccess == true或&& t2.IsFullAccess
