Linq to SQL中的派生表

Question

我想在Linq to SQL中实现它：

select * from (
    select * from Orders) as A

显然这是一个毫无意义的例子，但我无法弄清楚如何做到这一点！

Answer 1

尝试这样的事情：

var subquery = from row in Orders select row;
var query = from row in subquery select row;

Answer 2

using (var dc = new NorthwindDataContext())
{
             var A = from ordOuter in
                 from ordInner in dc.Orders
                 select ordInner
             select ordOuter;
}
