MVC3如何將數據傳遞到控制器的控制器

Question

將數據從控制器傳遞到另一個控制器。這是我在做什麼，但我不認爲這是做這件事的正確方法，plz幫助我修改代碼，它的工作，例如共享/教程..

如

我使用成員身份API來創建用戶帳戶

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"); 

}

聯繫控制器

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... 
} 

我希望這是清楚什麼，我試圖做的。也許使用ViewModels，但我不知道如何把它放在一起......謝謝！

Answer 1

您可以直接通過您的UserID參數到控制器的方法，因爲它是一個標準導航流量

RedirectToAction有一個overload，允許您設置routeValues。

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

而在你CompanyController

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

既然你將擁有URL您id，那麼你就可以抓住它在您的文章，以及：

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

或者您可以將其保存到模型CompanyInformation上GET Create

Answer 2

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

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

使用TempData
