将ID传递给URL，ASP.NET MVC

Question

I am trying to pass an id to the URL, However I cant hard code the ID but I need to pass the id from the model.

It is basically a collection of a particular type of model displayed as a table. When the user clicks on the id value of the table i need to be able to pass the id to the URL so that it can open a corresponding detailed page of the same.

<a href="~/Instance/Details/id=@Url.Encode(modelitem => item.Id)">   @Html.DisplayFor(modelitem => item.Id)</a>

This is what I am trying, need help:).

First of all, use the Url.Action method to generate the correct relative url to the action method.

@foreach (var item in SomeCollection)
{
  <div>
       <a href="@Url.Action("Details","Instance",new { id = item.Id })"> 
                                            @Html.DisplayFor(modelitem => item.Id)
       </a>
  </div>
}

The Url.Action method will generate the url value to details action method, which includes the item.Id value in the url.

Assuming Instance is the controller name where your Details action method is present with id parameter.

public class InstanceController : Controller
{
   public ActionResult Details(int id)
   {
      return Content("Details of "+id);
      // to do : return a view with data queried using id
   }
}
