Question

问题：EF-Core 1.1中是否可以实现上述目标？我尝试了以下操作但VS2015在Select new TestViewModel{...}行投诉时出现错误：name Select does not exist in the current context。如果以上是不可能的，那么在使用include(...)的情况下，什么是变通方法？注意：Customers已加入Addresses和Orders表

var qry = from c in _context.Customers.Include(t => t.Addresses).Where(c => c.Region== "NW").OrderBy(c => c.Name)
 join ord in _context.Orders  on c.CustomerID equals ord.CustomerID
Select new TestViewModel
{
   CustName = c.Name,
   CustRegion  = c.Region,
   OrderType = ord.Type,
   ....
};

Answer 1

select是关键字，关键字区分大小写。就像你不能宣布课程Public Static一样 - 你不能使用Select。

带有include（）的EF-Core LINQ JOIN
