When you insert entity, DbContext assigns created entity id. Then you can pass that id to your second page in querystring parameter.
插入实体时，DbContext会分配创建的实体ID。然后你可以在querystring参数中将该id传递给你的第二页。
_context.Auctions.Add(auction);
_context.SaveChanges();
// auction.Id now contains database generated id
// pass it to second page, like this in asp.net mvc
return RedirectToAction("SecondPage", new { auctionId = auction.Id });
Second page:
第二页：
public ActionResult SecondPage(int auctionId) { ... }
