爲什麼我在ASP.NET MVC中出現這個錯誤？

Question

錯誤：

傳遞到字典的模型產品類型「EventManagmentSystem.Models.RegisterPageModelViewModel」的，但這種字典需要類型的模型項目「EventManagmentSystem.Models.RegisterViewModel」。

控制器：

namespace EventManagmentSystem.Controllers 
{ 
    public class CustomerController : Controller 
    { 
     // GET: Customer 
     public ActionResult Index() 
     { 
      return View(); 
     } 
     public ActionResult Register(RegisterPageModelViewModel rm) 
     { 
      if(ModelState.IsValid) 
      { 

       RegistrationPageModel rp = new RegistrationPageModel 
       { 
        C_Name = rm.C_Name, 
        C_Password = rm.C_Password 
       }; 
      } 

      return View(rm); 
     } 
    } 
}

    public class RegisterPageModelViewModel 
    { 
     [Required(ErrorMessage = "Name is Required")] 
     public string C_Name { get; set; } 

     [Required(ErrorMessage = "Password is Required")] 
     public string C_Password { get; set; } 
    }

RegistrationPageModel.cs：

namespace EventManagmentSystem.Models 
{ 
    public class RegistrationPageModel 
    { 
     public int C_ID { get; set; } 
     public string C_Name { get; set; }

     public string C_Gender { get; set; }

Answer 1

檢查哪些視圖應該由註冊在控制器返回。現在它返回Register.cshtml視圖和型號RegisterPageModelViewModel。但Register.cshtml需要型號RegisterViewModel，你有這個錯誤。

取決於你需要做什麼用RegisterViewModel改變模型的類型。可能是這樣的：

public ActionResult Register(RegisterPageModelViewModel rm) 
{   
    ... 
    RegisterViewModel model = new RegisterViewModel{...}; 
    return View(model); 
} 

或更改視圖是如下：

public ActionResult Register(RegisterPageModelViewModel rm) 
{   
    ... 
    return View("RegisterPageModelViewModel", rm); 
}
