Question

我想去这个地方。在项目中，我们首先创建一个调查。然后单击调查旁边的按钮以查看调查的问题。

Survey's List. And "Soruları Gör" is that button.

单击按钮后，我们转到另一个控制器的索引页面。像这样， Survey's Questions' Index Page. Click on the button in the box to add a new question to the survey.

我想将调查的ID发送到新的问题页面并在该页面上显示。 new question creation page

我希望调查的ID出现在图片3的红色框中。

This view belongs to the 2nd picture. 

@model IEnumerable<PerformansTakipAnket.Models.View_Base_UyeAnketSorular_Getir>

希望我能告诉你问题所在。

您必须将SurveyId从操作方法传递到问题列表视图，并在呈现“创建”链接时使用该ID来将SurveyId添加为查询字符串。

看起来您没有视图模型，在这种情况下，您可以使用ViewBag传递此数据。

public ActionResult Index(int id)
{ 
   var questions = db.Questions.Where(a=>a.SurveyId==id).ToList();
   ViewBag.SurveyId = id;
   return View(questions);
}

现在，在您的视图中，您可以使用此ViewBag项值来填充ActionLink辅助方法的RouteValueDictionary参数。

@Html.ActionLink("Yeni Soru", "Create",new { surveyId= ViewBag.SurveyId })

假设您的Create操作方法具有一个名为surveyId的参数

public ActionResult Create(int surveyId)
{
  // Use surveyId as needed ( Pass to view via ViewBag/ViewModel)
  // to do :return something
}

我还建议研究视图模型，而不是通过ViewBag / ViewData传递数据。恕我直言，这更是一种干净的方法。

@ Html.ActionLink可以发送ID，并在其他视图中查看ID
