Question

将数据从控制器传递到另一个控制器。这就是我在做什么，但我不认为这是正确的做法，plz帮我修改代码让它工作，分享示例/教程..

e.g

我正在使用Membership API来创建用户帐户

public ActionResult Register() { return View(); }

[HttpPost]
public ActionResult Register(RegisterModel model)
{
  //creates an account and redirect to CompanyController
  //Also I want to store the userId and pass it to the next controller, I am using a session, ok? 
  Session["userObject"] = userIdGenerated()
  return RedirectToAction("Create", "Company");          
}

CompanyController：

public ActionResult Create() { return View(); }

[HttpPost]
public ActionResult Create(CompanyInformation companyinformation)
{
   //creating company account and I need to store the userid to the company table retrieving from a session
   companyinformation.UserID = Session["userObject"].ToString();
   db.CompanyInformation.Add(companyinformation);
   db.SaveChanges();

   //retrieving companyId that was generated and need to pass to the next controller I tried to use "TempData["companyId"] = companyinformation.CompanyInformationID" But the data is no longer found on httpPost

return RedirectToAction("Create", "Contact");

}

联系控制器

  public ActionResult Create()
  {
   //I tried using ViewBag to store the data from TempDate but the data is no longer found on httpPost
        ViewBag.companyId = TempData["companyId"].ToString();
        return View();
   }

 [HttpPost]
 public ActionResult Create(CompanyContact companycontact)
 {
     companycontact.CompanyInformationID = ???? How do I get the companyId?
     db.CompanyContacts.Add(companycontact);
     db.SaveChanges();
    //Redirect to the next controller...
 }

我希望我很清楚我想要做什么。也许使用ViewModels，但我不知道如何把它放在一起......谢谢！

Answer 1

public ActionResult Action1()
{
   TempData["key"]  =Some_Object;
  return RedirectToAction("Action2");
}

public ActionResult Action2()
{
     var data= TempData["key"];
}

使用TempData

Answer 2

您可以将UserID参数直接传递给控制器的方法，因为它是标准导航流程

RedirectToAction有一个overload，可让您设置routeValues。

  return RedirectToAction("Create", "Company", new { id = userIdGenerated() });

在CompanyController

中

public ActionResult Create(int id) { return View(id); }

由于您的网址中包含id，因此您也可以在帖子中找到它：

[HttpPost]
public ActionResult Create(int id, CompanyInformation companyinformation)

或者您可以将其保留在GET CompanyInformation

上的模型Create中
