ASP.NET Web表单MapHttpRoute中的WEB API

Question

I've been racking on my brain on this for a little bit now. I have built a web api, and I am now moving it to a web forms application. Every tutorial I have read says do it the way I am attempting to do. I have also checked the web for an answer to this, but they all suggest things I have already tried. The error I am getting is:

System.Web.Routing.RouteCollection does not contain a definition for MapHttpRoute

Here are my namespaces and my Application_Start method:

<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Web.Http" %>
<%@ Import Namespace="System.Web.Routing" %>

<script language="C#" runat="server">

void Application_Start(Object sender, EventArgs e) {


    RouteTable.Routes.MapHttpRoute(
           name: "apiCall",
           routeTemplate: "api/{controller}/{key}/{args}",
           defaults: new { args = System.Web.Http.RouteParameter.Optional }
       );

}

Any help as to what I am doing wrong would be greatly appreciated.

Are you sure you have the correct using statement? I think this is the one you want:

Answer 2

Thanks for the hepl, but I ended up adding my web api to my project through Visual Studio, and it fixed itself. I had just been trying to add in windows explorer.

Answer 3

I had this problem and I fixed it by adding this assembly reference : System.Web.Http.WebHost
