强类型MVC视图模型

Question

I am trying to strongly type my MVC View Model that is rendered as a ASP.NET ASPX page. Everything is in one big project. However, it say it can't find the name space, what am I doing wrong?

Here is the error:

CS0234: The type or namespace name 'MyModel' does not exist in the namespace 
'MyProject.Models' (are you missing an assembly reference?)

Here is my custom Model:

namespace MyProject.Models {
    public class MyModel{
        public string companyID { get; set; }
        public MyModel(string companyID){
            this.companyID = companyID;
        }
    }
}

Here is my Strongly Typed View rendered in ASPX, with the filename MyStronglyTypedView.aspx:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MyProject.Models.MyModel>" %>
<%@ import namespace='MyProject.Models' %>
.....
<script runat="server">
    protected void Page_Load(object sender, EventArgs e) {
        var curCompany = Model.companyID;
    }
</script>
....

And here is how I am calling the page and passing my model to it (I am calling it on a separate Razor page as a partial):

@Html.Partial("MyStronglyTypedView",new MyProject.Models.MyModel("1"))

The error you are experiencing occurs because of incorrect Page directive Inherits attribute value. Directives are part of the ASP.NET markup and thus are not language-specific. For example

System.Web.Mvc.ViewPage<MyProject.Models.MyModel>

is how you specify generic type in C#, but say in VB.NET it would be

System.Web.Mvc.ViewPage(of MyProject.Models.MyModel)

All in all, types here should be specified in CLR notation. In your case it might look something like

System.Web.Mvc.ViewPage`1[[MyProject.Models.MyModel, MyProject, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]

This is so called Fully Qualified Type Name. To see this name for a particular type, one can use Type.FullName property:

Type targetType = typeof(System.Web.Mvc.ViewPage<MyProject.Models.MyModel>);
string name = targetType.FullName;
