asp.net-mvc-4 - MVC 4 Actionlink Parameter Not Passed To Controller Action

Question

I have a View within my MVC 4 application, whereby the user types in a first and last name and hits the search button. Once they do this, an action in my controller is called

[HttpPost]
public ActionResult ChangeLineManager(RegisterLineManagerModel model, int? id)
{

    if (ModelState.IsValid)
    { 
       if (id == null)
       {
         // Search for person using model.SearchFName and model.SearchLName
       }
       else
       {
         // User has selected manager from returned list of people
       }

    }
}

Once the user performs a search and if data is returned, I list the data

@foreach (var user in Model.LineManagers)
{
  <tr>
   <td>@Html.ActionLink(linkText: "Select Manager", 
       actionName: "ChangeLineManager", 
       controllerName: "Portfolio", 
       routeValues: new { id = (int?)user.ApplicantID }, htmlAttributes: null)
   </td>
  </tr>
}

Ideally, I would like the user to then click the 'Select Manager' link beside their appropriate manager, however, whenever I test this, nothing happens, the ChangeLineManager action within my Controller is not called.

Does anyone have any suggestions on how to fix this?

Thanks for your time.

操作链接将呈现到标签。当用户单击此标签时，GET 请求会转到服务器，但在您的控制器中仅 POST ChangeLineManager。你需要添加这样的东西

[HttpGet]
public ActionResult ChangeLineManager(int? id)
{
    //some logic

}
