Three ways that ASP. NET MVC spreads values to view views

This article summarizes the three common ways that ASP. NET MVC will pass values to view views:

--------------------------------------------------------------------------

1. Pass through the parameters of view (parameter)

Action

Public ActionResult Index ()

{

Person Person=new person ("Wumiao", 18,175);

Return View ("Index", person);

}

View

@using test_01//Add a reference to the namespace where the custom class resides

@{var person= (person) Viewdata.model; }

Name: @person. Name-Age: @person. Age-Height: @person. Height

---------------------------------------------------------------------------

2. Transfer via Viewbag.key

Action

Public ActionResult Index ()

{

Person Person=new person ("Wumiao", 18,175);

Viewbag.person=person;

return view ();

}

View

@using test_01

@{var person= (person) viewdata.per;}

Name: @person. Name-Age: @person. Age-Height: @person. Height

------------------------------------------------------------------------

3. Pass through Viewdata[key]

Action

Public ActionResult Index ()

{

Person Person=new person ("Wumiao", 18,175);

viewdata["Person"]=person;

}

View

@using test_01

@{var person (person) viewdata[' person ';}

Name: @person. Name-Age: @person. Age-Height: @person. Height
