c# - 选择项目时，剃刀过滤器下拉列表不过滤

Question

您好，我有一个页面有两个完全相同的过滤器，但其中一个无法正常工作，我不确定我的代码有什么问题！

先感谢您！

这是我在视图中的代码：

@Html.DropDownList("Projects", (SelectList)ViewBag.Projects, "请选择一个项目...", htmlAttributes: new { @class = "form-control" })

这是我的控制器中的代码：

    public ActionResult Index(string projects, int? EmployeeId)

    {
        var status = db.Projects.Select(m => new SelectListItem { Value = 
m.ProjectName.ToString(), Text = m.ProjectName }).Distinct().ToList();


        ViewBag.Projects = new SelectList(status, "Value", "Text");

        ViewBag.EmployeeId = db.Employees.Select(p => new SelectListItem
        {
            Text = p.FirstName + " " + p.LastName,
            Value = p.ID.ToString()
        });


        var employee = db.EmployeeTimesheets.Where(student => student.Projects != null);

        if (!string.IsNullOrEmpty(projects))
        {
            employee = employee.Where(student => student.Projects == projects);
        }

        if (EmployeeId > 0)
        {
            employee = employee.Where(student => student.EmployeeId == EmployeeId);
        }

        return View(employee);
    }
