将Action动作中传递的FormCollection转变成对应的实体，可以使用Controller的TryUpdateModel()方法。
[HttpPost]
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");
}
}
也可以直接使用实体作为参数：
public ActionResult Create([Bind(Include = "Id,Code,Name")] Student studentModel)
