Question

我有mvc 3应用程序，其中在会话对象中我正在获取所需的所有值以我作为执行存储过程的参数。

如果userAction更新，则执行存储过程。

  public ActionResult Index(string userAction)
    {
       if(Session["Mappings"] != null)           
            ViewData["Message"] = "Mapping web grid";

        if (Session["PricingSecurities"] == null)
            Session["PricingSecurities"] = objRepository.GetPricingSecurityID();
        if (Session["Cusips"] == null)
            Session["Cusips"] = objRepository.GetCUSIP();

        SecurityMappingModel objModel = null;
        mappings = (List<SecurityMappingModel>)Session["Mappings"];

        objModel = new SecurityMappingModel();


        if (userAction == "Update" )
        {
            //please tell me how can i take values from Session[Mappings] and pass it to stored procedure?

            return RedirectToAction("Index");
        }
        objModel.PricingSecirities = (List<SelectListItem>)Session["PricingSecurities"];
        objModel.Cusips = (List<SelectListItem>)Session["Cusips"];
        ViewBag.Mappings = mappings;
        return View(objModel);
    }

如何从Session [Mappings]获取值并将其传递给存储过程？

你需要做这样的事情：

    using (MyEntitiesDataModel context = new MyEntitiesDataModel())
    {
        context.ExecuteStoreCommand(
            "exec MyStoredProc @param1={0}, @param2={1}",
            Session["foo"], Session["bar"]);
    }

... MyEntitiesDataModel 是您的EF数据模型， MyStoredProc 是您存储过程的名称。

如何使用EF将参数传递给mvc 3中的存储过程？
