如何使用 viewbag 将一列数据作为列表传递到强类型视图
任何人都可以为我指明如何使用 viewbag 将列表中的一列数据传递到强类型视图的正确方向。我正在使用强类型视图传递 CustomerSites 列表。我还想在列表中每个 CustomerSite 旁边显示 CustomerName。
我已尝试以下方法，但由于控制器返回客户列表，因此它不允许我从视图访问 CustomerName 属性，是否可以从视图访问此属性？
public ViewResult Index()
{
var q = from a in db.Customers.ToList()
select a;
ViewBag.customer = q;
return View(db.CustomerSites.ToList());
}
@model IEnumerable<trsDatabase.Models.CustomerSite>
@foreach (var customer in Model)
{
<tr>
<td>
@ViewBag.customer.CustomerName
</td>
<td>
@customer.UnitNo
</td>
<td>
@Truncate(customer.StreetName, 25)
</td>
<td>
@customer.Town
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { id=customer.Id }) |
@Html.ActionLink("Details", "Details", new { id=customer.Id }) |
@Html.ActionLink("Delete", "Delete", new { id=customer.Id })
</td>
</tr>
}
Can anyone point me in the right direction as to how to pass one column of data in a list using viewbag to a strongly typed view. I am passing a list of CustomerSites using a strongly typed view. I would also like to display a CustomerName next to each CustomerSite in the list.
I have tried the following approach, but as the controller is returning a list of customers it wont let me access the CustomerName property from the view, is it possible to access this property from the view?
public ViewResult Index()
{
var q = from a in db.Customers.ToList()
select a;
ViewBag.customer = q;
return View(db.CustomerSites.ToList());
}
@model IEnumerable<trsDatabase.Models.CustomerSite>
@foreach (var customer in Model)
{
<tr>
<td>
@ViewBag.customer.CustomerName
</td>
<td>
@customer.UnitNo
</td>
<td>
@Truncate(customer.StreetName, 25)
</td>
<td>
@customer.Town
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { id=customer.Id }) |
@Html.ActionLink("Details", "Details", new { id=customer.Id }) |
@Html.ActionLink("Delete", "Delete", new { id=customer.Id })
</td>
</tr>
}

我鼓励您将根据 CustomerSites 和 CustomerNames 构建的 ViewModel 传递给 View。为什么不从由客户名称和站点组成的数据库对象中获取？
I would encourage you to pass to the View a ViewModel built out from CustomerSites and CustomerNames. Why don't you get from the DB object which consists from Customer name and site?
在我看来，
ViewBag.customer保存了Customers的集合，而不是单个Customer对象。在您的查询中，您应该有一个where部分。It seems to me that
ViewBag.customerholds a collection ofCustomersnot a singleCustomerobject. In your Query you should have awherepart.
