Methods for returning multiple models or datasets from the same view using ASP. NET MVC

Asp.net MVC, by default, only one model can be returned at a time. If multiple datasets are called, viewdata can only be used for export. It seems very troublesome, you can implement the model extension method ( declare that this method is only applicable to MVC2, and supports generic type after mvc3. It is very convenient to directly use viewbag to pass it over. )

First, define a class in the controller. The content is as follows:
Public Class Blogmodel
{
Public Iqueryable <t_type> types { Get ; Private Set ;}
Public Iqueryable <t_post> posts { Get ; Private Set ;}
Public Blogmodel (iqueryable <t_type> types, iqueryable <t_post> posts)
{
This . Types = types;
This . Posts = posts;
}
}

To receive two iqueryable messages and then return

Iqueryable <t_type> types = From T In CB. t_typeSelect T;
Iqueryable <t_post> posts = ( From P In CB. t_post Orderby P. updatetime Select P). Take ( 10 );
// Viewdata ["message"] = "Welcome to ASP. net mvc! ";
Return View ( " Index " , New Blogmodel (types, posts ));

 

The first line of the View File to be referenced
<% @ Page Language = " C # " Masterpagefile = " ~ /Views/shared/site. Master " Inherits = " System. Web. MVC. viewpage <mvcblog. controllers. blogmodel> "   %>

Then you can use the types and posts datasets !!!
