ASP.NET MVC 中将FormCollection与实体间转换方法

public ActionResult Create(FormCollection collection)
{
    try
    {
        if (ModelState.IsValid)
        {
            var student = new Student();
            //在这里转换
            TryUpdateModel<Student>(student, collection);
            dalStudent.Add(student);
            return RedirectToAction("Index");
        }
        else
            return View();
    }
    catch
    {
        return View("Create");
    }
}
