Creating an MVC Link through Url.Action Inside a Web API Controller

Question

I am trying to create an MVC link via Url.Action inside my Web API Controller

string scheme = Request.RequestUri.Scheme;
System.Web.Mvc.UrlHelper helper = new System.Web.Mvc.UrlHelper();
string linkBackUrl = helper.Action("TestAction", "TestController", new{ code=code1, code2 = code2}, scheme);

And I am getting the error (when debugging) on the line linkBackUrl:

attempted to read or write protected memory. this is often an indication that other memory is corrupt.

Is there another way to create the linkBackUrl inside the Web API controller?

If you are trying to get a reference of the current HttpContext try this: System.Web.Mvc.UrlHelper helper = new System.Web.Mvc.UrlHelper(HttpContext.Current.Request.RequestContext); — IndieTech Solutions

No need to build your own UrlHelper in an ApiController--it comes with one — Brad Christie

I think this is what your looking for :

         string linkBackUrl = Url.Action("TestAction", "TestController", new { code = code1, code2 = code2 });

Or on your view:

<button onclick="window.history.back();">Go Back</button>
