MVC View not passing data to Controller

Question

I have this view which is not passing data to the controller. Why is this happening?

View:

@Html.DisplayFor(model => model.threadID)
@Html.ActionLink("Add Post", "CreatePost", "Threads", new { id = Model.threadID })

CreatePost Method in Threads Controller:

[HttpGet]
public ActionResult CreatePost(string id)
{
    PostModel model = new PostModel(id);
    return View(model);
}

The DisplayFor in the view is diplaying the ID (string), however when calling the CreatPost method in the controller, the id being passed is null

我认为你使用了错误的重载方法，试试这个：

@Html.ActionLink("Add Post", "CreatePost", "Threads", new { id = Model.threadID }, null)
