To get listbox selected values in asp.net mvc3

In asp.net Mvc3 razor, I have binded some data with dbcontext in my controller viewbag using selectlist

My controller..

public ActionResult Index()
        {
            ViewBag.students = new SelectList(db.StudentList, "StudentID", "StudentName");
            return View();
        }

Then I binded it to the ListBox using viewbag

My View..

@using (Html.BeginForm("Save", "Student"))
{    
    @Html.ValidationSummary(true)
    <div>
     @Html.ListBox("students")
    <p>
        <input type="submit" name="Save" id="Save" value="Save" />
    </p>
    </div>
}

Now, in my controller, in that Save action, I need to capture the listbox selected values I have tried the following 

[AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Save(FormCollection formValue) 
        {
            //need code to capture values                
            return View("Index");
        }

Could anyone help

Thanks in advance

Try the following 

 @Html.ListBox("students",ViewBag.students )

From form collection get the value of 'students'. For that please refer the following page

Pulling ListBox selected items from FormCollection

For a nice implementation of listbox in MVC please read this article.

Try that:

public class StudentController : Controller
{
    //
    // GET: /Student/

    public ActionResult Index()
    {
        var studentList = new List<Student>
                              {
                                  new Student {StudentID = 1, StudentName = "StudentName1"},
                                  new Student {StudentID = 2, StudentName = "StudentName2"},
                                  new Student {StudentID = 3, StudentName = "StudentName3"},
                                  new Student {StudentID = 4, StudentName = "StudentName4"}
                              };

        ViewBag.students = new SelectList(studentList, "StudentID", "StudentName");
        return View();
    } 

    [HttpPost]
    public ActionResult Save(String[] students)
    {
        return View();
    }

}

public class Student
{
    public int StudentID { get; set; }
    public string StudentName { get; set; }
}
