Question

我有一个带有＆＃34; HasBeenShipped＆＃34;的ViewModel;这是一个布尔值，如何在我的控制器中将它发送到视图;

如果（hasbeenshipped = false）

我想发送给视图的消息其他订单已发货

在视图中我将如何显示其中一个？可能有一个我认为的背包？

这是我的控制器

public ActionResult Index()
{
    string currentUser = this.User.Identity.GetUserName();

    List<T_shirt_Company_v3.ViewModels.MyOrdersViewModel> list = (from o in new TshirtStoreDB().Orders
            .Where(o => o.Username == currentUser)
            .OrderBy(o => o.OrderDate)
            .Select(o => new MyOrdersViewModel()
            {
                OrderId = o.OrderId,
                Address = o.Address,
                FirstName = o.FirstName,
                LastName = o.LastName,
                City = o.City,
                OrderDate = o.OrderDate,
                PostalCode = o.PostalCode,
                Total = o.Total,
                HasBeenShipped = o.HasBeenShipped,
                Details = (from d in o.OrderDetails
                           select new MyOrderDetails
                           {
                               Colour = d.Product.Colour,
                               Quantity = d.Quantity,
                               Title = d.Product.Title,
                               UnitPrice = d.UnitPrice
                           }).ToList()
            }).ToList()select o).ToList();


    //ViewBag.ShippedMessage = HasBeenShipped ? "blah" : "not shipped";


    return View(list);

Answer 1

因为ViewModel包含HasBeenShipped，所以这应该有效：

<强> View.cshtml

@model List<T_shirt_Company_v3.ViewModels.MyOrdersViewModel>

@foreach (var item in Model)
{
    <span>@(item.HasBeenShipped ? "..." : "...")</span>
}

不需要使用ViewBag，或者只有在必须从外部源加载消息本身时才需要使用ViewBag。

Answer 2

在您的控制器中使用ViewBag。如

ViewBag.ShippedMessage = list.Where(w=>w.HasBeenShipped).Any() ? "blah" : "not shipped";

然后在您的视图中，您可以访问该属性

<p>@ViewBag.ShippedMessage</p>

C＃将布尔值作为消息传递
