Asp.net mvc 如何将代码转换为此RequestPurchase IdrequestPurchase=db.RequestPurchase.Find（id）；

如何改变这一点

RequestPurchaseItem re = db.RequestPurchaseItem.Where(x=>x.RequestPurchaseNumber == id).ToList();

对此

RequestPurchase IdrequestPurchase = db.RequestPurchase.Find(id);

因为我需要喜欢这个

RequestPurchase IdrequestPurchase = db.RequestPurchase.Find(id);

非常感谢……谢谢

很抱歉，我们无法理解您的问题

RequestPurchase IdrequestPurchase = db.RequestPurchase.ToList().Find(x=>x.RequestPurchaseNumber == id);
