如何获取登录用户的ID

Question

我有一个请求表单，我想在会话IdEmpLogin中获取用户的ID，以防我需要知道谁发出了请求

使用此模型

 public class NewRequestViewModel
{
    public int IdEmpLogin { get; set; }
    public int IdEmpTarget{ get; set; }
    public IDictionary<int, string> TargetUser{ get; set; }
    public int EmpTargetCarId{ get; set; }
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd-MM-yyyy HH:mm:ss}", ApplyFormatInEditMode = true)]
    public DateTime RequestDate{ get; set; }
    public int Status{ get; set; }
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd-MM-yyyy HH:mm:ss}", ApplyFormatInEditMode = true)]
    public <System.DateTime> ResponseDate { get; set; }
}

这是我的登录信息，对于我正在使用domain model

的登录信息

public ActionResult Login(String User, String Pass)
    {
        try
        {
            using (var db = new sir_cjfEntities())
            {
                var usr =(from d in db.employees
                          where d.user==User && d.password== Pass && d.status== true
                          select d).FirstOrDefault();
                if (usr == null)
                {
                    return Content("The username or password is incorrect");
                }
                else
                {
                    Session["user"] = usr;
                    return Content("1");
                }
            }
        }
        catch (Exception ex)
        {
            return Content("Error" + ex.Message);
        }
    }

Domain Model

public partial class employees
{
    public employees()
    {
        this.cars= new HashSet<cars>();
        this.parking= new HashSet<parking>();
        this.request= new HashSet<request>();
        this.request2= new HashSet<request>();
    }

    public int id_employee{ get; set; }
    public string name{ get; set; }
    public string lname{ get; set; }
    public string user{ get; set; }
    public string password{ get; set; }
    public Nullable<bool> status{ get; set; }

    public virtual ICollection<cars> cars{ get; set; }
    public virtual ICollection<parking> parking{ get; set; }
    public virtual ICollection<request> request{ get; set; }
    public virtual ICollection<request> request{ get; set; }
}

如何获取已登录员工的ID并将其保存在我的请求表中？

public ActionResult NewReq()
    {
        var model = new NewRequestViewModel
        {
            TargetUser= new Dictionary<int, string>()
        };
        using (var db = new sir_cjfEntities())
        {
            model.TargetUser= db.employees.ToDictionary(x => x.id_employee, x => x.name+ " " + x.lname);
        }
        return View(model);
    }
    [HttpPost]
    public ActionResult NewReq(NewRequestViewModel model)
    {
        var db = new parkingDBEntities();
        if (!ModelState.IsValid)
        {
            model.TargetUser= db.employees.ToDictionary(x => x.id_employee, x => x.name+ " " + x.lname);
            return View(model);
        }
        var req= new request();
        using (db)
        {
            model.RequestDate= DateTime.Now;
            model.TargetUser= db.employees.ToDictionary(x => x.id_employee, x => x.name+ " " + x.lname);
            req.status= null;
            req.id_emp_logged = model.IdEmpLogin;//get logged in user id
            req.id_emp_target = model.IdEmpTarget;//target user
            req.emp_tar_car_id= model.EmpTargetCarId; //I have to get the car registered by the target user
            req.request_date= model.RequestDate;
            db.request.Add(req);
            db.SaveChanges();
        }
        return Redirect(Url.Content("~/CRequest/"));
    }

如您所见，我目前正在手动输入ID

这是视图

@model ParkingRequest.Models.ViewModels.NewRequestViewModel 
@{
    ViewBag.Title = "New Request";
}

<h2>@ViewBag.Title</h2>

<div class="row">
    <div class="col-md-12">

        @using (Html.BeginForm("NewReq", "CRequest", FormMethod.Post, new { }))
        {
            @Html.AntiForgeryToken()
            @Html.ValidationMessage("Error", new { @class = "text-danger", @type = "text" })

            @Html.LabelFor(d => d.IdEmpLogin)
            @Html.TextBoxFor(d => d.IdEmpLogin, new { @class = "form-control" })
            @Html.ValidationMessage("IdEmpLogin", new { @class = "text-danger" })
            <br />
            @Html.LabelFor(d => d.IdEmpTarget)
            @Html.DropDownListFor(d => d.IdEmpTarget, new SelectList(Model.TargetUser, "Key", "Value"),
          new { @class = "form-control" })
            @Html.ValidationMessage("IdEmpTarget", new { @class = "text-danger" })
            <br />
            @Html.LabelFor(d => d.EmpTargetCarId)
            @Html.TextBoxFor(d => d.EmpTargetCarId, new { @class = "form-control" })
            @Html.ValidationMessage("EmpTargetCarId", new { @class = "text-danger" })
            <br />
            <div style="text-align:right;">
                <input type="submit" class="btn btn-success" value="Apply for" />
            </div>
        }
    </div>
</div>
