Three ways to pass values to the view of the MVC controller

1. Providing a view model object

You can pass an object to the view as a parameter of the view method.

  [CSharp]  view plaincopyprint? 
   
  
 
    
   
< Span style= "color: #ffffff;" >public   viewresult index ()    
 
    
   
{&NBSP;&NBSP;  
 
    
   
DATETIME&NBSP;DATE&NBSP;=&NBSP;DATETIME.NOW;&NBSP;&NBSP;  
 
    
   
return   view (date);     
 
    
   
}     
 
   
  
 
 

We then use the Razor model keyword in the view to access the object

1. < Span style= "color: #ffffff;" >@{  
2. viewbag.title = ;   
3. }&NBSP;&NBSP;
4. <H2>INDEX</H2>&NBSP;&NBSP;
5. the day is :  @ (((DateTime) Model). DayOfWeek)

2. @model DateTime
4. @{
6. Viewbag.title = "Index";
8. }
12. The day is: @Model. DayOfWeek

2. Passing Data using ViewBag (view pack)

View Bag allows you to define any property on a dynamic object and access it in a view. This dynamic object can be accessed through the Controller.viewbag property.

 Public ViewResult Index ()
   
  

  
{
   
  

  
Viewbag.message = "Hello";
   
  

  
Viewbag.date = DateTime.Now;
   
  

  
return View ();
   
  

  
}
   
  

  

   
  

  
@{
   
  

  
Viewbag.title = "Index";
   
  

  
}
   
  

  

   
  

  
The day is: @ViewBag. Date.dayofweek
   
  

  
<p/>
   
  

  
The message is: @ViewBag. Message
  
 

3. Passing Data using view data

Before MVC3.0, the main way to pass data is by using the Viewdatadictionary class instead of a dynamic object. The Viewdatadictionary class is similar to the standard "key/value" collection and is

The ViewData property of the controller class is accessed. This method requires that the object be converted in the view.

2. In the controller:
4. Public ViewResult Index ()
6. {
8. viewdata["Message"] = "Hello";
10. viewdata["Date"] = DateTime.Now;
12. return View ();
14. }
18. In the View:
20. @{
22. Viewbag.title = "Index";
24. }
28. The day is: @ (((DateTime) viewdata["Date"). DayOfWeek)
30. <p/>
32. The message is: @ViewData ["message"]
