我想要做的是将一个新创建的OrderID从我的“Order Controller创建表单”传递到“OrderItem Controller创建表单”，并添加与OrderID我刚刚传递的特定内容相关的Order_Items 。我设法重定向了Create Order按钮，使我直接进入OrderItem Index Form，但是当我想添加new时，它仍将所有以前创建的OrderIDs包括新创建的按钮拉出。我希望表单仅提取我刚刚创建的表单，而不是其他所有先前创建的表单。OrderIDOrderItemsOrderIDOrderIDs
另外，我将其重定向到“订单项目索引表”的原因是，我可以看到与该特定项目相关的所有“订单项目” OrderID，但仍显示OrderItems为每个订单创建的所有项目OrderID。
我不知道如何执行此操作，因为我还不熟悉MVC，因此非常感谢所有帮助。

尚不清楚您的Index()方法的目的是什么OrderItemController。您只显示所有订单的所有订单项目。通常，您的Details()方法OrderController将显示订单的详细信息以及与该订单相关的项目的列表（例如，一张表，其中显示每个OrderItem的所有详细信息，包括编辑/删除链接，或者如果太多的Details()方法链接到该方法OrderItemController显示在一页上的信息）
我建议以下结构
OrderController
public ActionResult Index()
{
// Display a collection on all orders
}
public ActionResult Details(int ID)
{
// Display the details of an order, including a collection of its order items
}
public ActionResult Create()
{
// Create a new Order
}
[HttpPost]
public ActionResult Create(Order model)
{
// Save the order
return RedirectToAction("Details", new { ID = model.ID });
}
Details.cshtml然后，该视图将包含一个链接（菜单项），以创建一个OrderItem与Order
@Html.ActionLink("Create Item", "Create", "OrderItem", new { ID = Model.OrderID }, null)
OrderItemController
public ActionResult Create(int ID) // ID is the ID of the Order
{
OrderItem model = new OrderItem() { OrderID = ID };
return View(model);
}
[HttpPost]
public ActionResult Create(OrderItem model)
{
// Save the OrderItem and redirect to the order details page
return RedirectToAction("Details", "Order", new { ID = model.OrderID });
}
在的Create.cshtml视图中OrderDetails，OrderID在表单中包含作为路线值，或在表单内包含隐藏的输入
@model OrderDetail
@using (Html.BeginForm(new { OrderID = Model.OrderID }))
{
....
}
旁注：建议您遵循常规的命名约定-OrderItem而不是Order_Item-并使用视图模型，尤其是在创建/编辑和删除那些糟糕的[Bind(Include = "...")]属性时。
