我想将模型作为参数传递给我的控制器中的FileStreamResult,但我得到null。这是我希望在m
中获取模型的控制器文件[HttpPost]
public FileStreamResult GETPdf(MarkModel m)// here i want value from my view
{
var MarkRe = new List<Mark>();
var mark = new List<MarkModel>();
using (StudentInfoSystemEntities db = new StudentInfoSystemEntities())
{
mark = (from e in db.Marks
from s in db.Students
where e.StudentId == s.ID
&& e.StudentId == m.StudentId
select new MarkModel
这是我想要向控制器发送值的视图
<div class="editor-field">
@Html.DropDownListFor(m => m.StudentId, @ViewBag.Students as List<SelectListItem>)
@Html.ValidationMessageFor(m => m.StudentId)
</div>
<div>
Export Data : @Html.ActionLink("Export to PDF", "GETPdf", "GetMarkRec")
</div>
