Three ways to pass values to the view of the ASP.

Transferred from: http://www.cnblogs.com/shinima/p/3940452.html

1. Providing a view model object

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

1. Public ViewResult Index ()
2. {
3. DateTime date = DateTime.Now;
4. return View (date);
5. }

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

1. @{
2. Viewbag.title = "Index";
3. }
5. The day is : @ ((DateTime) Model). DayOfWeek)

or a

1. @model DateTime
2. @{
3. Viewbag.title = "Index";
4. }
6. 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.

2. Public ViewResult Index ()
4. {
6. Viewbag.message = "Hello";
8. Viewbag.date = DateTime.Now;
10. return View ();
12. }
16. @{
18. Viewbag.title = "Index";
20. }
24. The day is : @ViewBag. Date.dayofweek
26. <p/>
28. 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"]
