c# - LINQ 中的 If Else

Question

是否可以在 LINQ 查询中使用 If Else 条件？

有点像

from p in db.products
if p.price>0
select new
{
  Owner=from q in db.Users
        select q.Name
}
else
select new
{
   Owner = from r in db.ExternalUsers
            select r.Name
}

Answer 1

这可能有用...

from p in db.products
    select new
    {
        Owner = (p.price > 0 ?
            from q in db.Users select q.Name :
            from r in db.ExternalUsers select r.Name)
    }
