为什么我的httpget不起作用？

Question

大家好：我正在创建一个ASP.net项目，这里是一个有问题的文件夹：

Dashboard :
--> DashboardIndex.cshtml
--> DashboardPage.cs
--> DashboardPageModel.cs

我的页面生成以下代码

<div class="small-box bg-aqua">
    <div class="inner">
        <h3>@Model.OpenOrders</h3>
        <p>Open Orders</p>
    </div>
    <div class="icon">
       <i class="ion ion-bag"></i>
    </div>
    <a href="/IP/1/11_2" class="small-box-footer">More info <i class="fa fa-arrow-circle-right"></i></a>
</div>

我点击按钮，导致我http://localhost:21739/IP/1/11_2

Aaand ..错误404！

然而，我编码了似乎是合适的函数（我与另一个函数I代码进行了比较（哪个有效），我没有发现任何相关的差异）

任何人都知道出了什么问题？
