asp.net-mvc - 使用 ASP.NET MVC 将多个 View 返回到一个 ActionResult

本质上我想实现的是:

Items assigned to me

Item 1 assigned to me
Item 2 assigned to me
Item 3 assigned to me


All open items
Item 1 open to everyone
Item 2 open to everyone
Item 3 open to everyone
Item 4 open to everyone

虽然到目前为止我对 MVC 的体验是我必须将数据返回到 View 模型才能以下列方式在 View 本身中使用它:

<asp:Content ID="ticketsContent" ContentPlaceHolderID="MainContent" runat="server">
    <div id="hdMain">
        <div id="hdMainTop"><img src="images/hdMainTop.gif" alt="" /></div>
        <div id="hdMainContent">
            <div id="numberOfCalls">Calls assigned to you (<%=Html.ViewData("MyOpenCallsCount")%>)</div>
            <div id="assignedToMe">
                <div id="callHeaders">
                    <table id="callHeadersTbl" cellpadding="0" cellspacing="0">

        </div>
        </div>
</asp:Content>

现在，尽管我知道它行不通，但我的想法基本上是:

'
' GET: /Calls/
<Authorize()> _
Function Index() As ActionResult
    ViewData("OpenCallCount") = callRepository.CountOpenCalls.Count()
    ViewData("UrgentCallCount") = callRepository.CountUrgentCalls.Count()
    ViewData("HighCallCount") = callRepository.CountHighCalls.Count()
    ViewData("NormalCallCount") = callRepository.CountNormalCalls.Count()
    ViewData("LowCallCount") = callRepository.CountLowCalls.Count()

    ViewData("MyOpenCallsCount") = callRepository.CountMyOpenCalls(Session("LoggedInUser")).Count()
    ViewData("UserName") = Session("LoggedInUser")

    Dim viewOpenCalls = callRepository.FindAllOpenCalls()
    Dim viewMyOpenCalls = callRepository.FindAllMyCalls(Session("LoggedInUser"))

    Return View(viewOpenCalls)
    Return View(viewMyOpenCalls)
End Function

我想知道的是，执行此操作的正确方法是什么？我不知道如何走正确的路，我想我至少有理论，但不知道如何实现。

提前感谢您的帮助。

编辑

根据以下评论，我进行了以下代码编辑/添加:

Class Calls
    Private _OpenCalls As hdCall
    Public Property OpenCalls() As hdCall
        Get
            Return _OpenCalls
        End Get
        Set(ByVal value As hdCall)
            _OpenCalls = value
        End Set
    End Property
    Private _MyCalls As hdCall
    Public Property MyCalls() As hdCall
        Get
            Return _MyCalls
        End Get
        Set(ByVal value As hdCall)
            _MyCalls = value
        End Set
    End Property
End Class

Index() 操作

'
' GET: /Calls/
<Authorize()> _
Function Index() As ActionResult
    ViewData("OpenCallCount") = callRepository.CountOpenCalls.Count()
    ViewData("UrgentCallCount") = callRepository.CountUrgentCalls.Count()
    ViewData("HighCallCount") = callRepository.CountHighCalls.Count()
    ViewData("NormalCallCount") = callRepository.CountNormalCalls.Count()
    ViewData("LowCallCount") = callRepository.CountLowCalls.Count()

    ViewData("MyOpenCallsCount") = callRepository.CountMyOpenCalls(Session("LoggedInUser")).Count()
    ViewData("UserName") = Session("LoggedInUser")

    Dim viewOpenCalls As New Calls With {.OpenCalls = callRepository.FindAllOpenCalls()}
    Dim viewMyOpenCalls As New Calls With {.MyCalls = callRepository.FindAllMyCalls(Session("LoggedInUser"))}

    Return View(New Calls())
End Function

            <div id="blueBottom"><img src="images/blueboxBottom.gif" /></div>
        </div>
        </div>
</asp:Content>

但是，<%=Html.ViewData("MyOpenCallsCount")%> 行给我一个语句结束预期错误。

此外，我确实让它编译了一次，但我得到了错误 Unable to cast object of type 'System.Data.Linq.DataQuery1[CustomerServiceHelpdesk.hdCall]' to type 'CustomerServiceHelpdesk.hdCall'.来自Dim viewOpenCalls As New Calls With {.OpenCalls = callRepository.FindAllOpenCalls()}行

我哪里出错了？

对于这样的事情我有点菜鸟，所以非常感谢任何帮助。

最佳答案

好吧，你不能从一个函数返回两个值，如果这是你想要做的(标题表明这就是你想要的)。
再加上这不是http无论如何工作。对于一个请求总是只有一个响应。

但是如果你想同时发送你的 viewOpenCalls和 viewMyOpenCalls对象到一个 View ，那么您可以通过让您的 View 有一个模型来容纳它们。

像这样:

//My VB is a bit rusty so I'm writing this in C#
class Calls {
    public yourDataType OpenCalls { get; set; }
    public yourDataType MyCalls { get; set; }
}

在你的 Controller Action 中:

return View(new Calls { OpenCalls = viewOpenCalls,  MyCalls = viewMyOpenCalls })

//I gues in VB it would be like this :
Dim viewOpenCalls = callRepository.FindAllOpenCalls()
Dim viewMyOpenCalls = callRepository.FindAllMyCalls(Session("LoggedInUser"))
Return View(New Calls _
    With {.OpenCalls = viewOpenCalls, .MyCalls = viewMyOpenCalls})

在您看来，确保它的模型是 Calls 的类型类。

<%@ Page Inherits="System.Web.Mvc.ViewPage<Calls>" %>

现在您可以使用 <%=Model.OpenCalls %> 访问属性和 <%=Model.MyCalls %>
