ASP. net mvc series: Add query function for views, asp. netmvc

First, add a query method in MoviesController. The Code is as follows:

Public ActionResult SearchIndex (string title) {// query the movie table var movies = from m in db. Movies select m; if (! String. isNullOrEmpty (title) {// query the movies = movies. where (m => m. title. contains (title);} return View (movies );}

Create a view for the SearchIndex method, and select the model class Movie and framework template List of the view.

After adding the view, we enter the URL http: // localhost: 60534/Movies/searchindex in the browser? Title = 123 (I have added the title = 3 data in the database), and it can query data for us.

Now we add a query button in the SearchIndex view to submit the query conditions through the button.

    @using (@Html.BeginForm())    {    <p>        Titile:@Html.TextBox("title")<br />        <input type="submit" value="Filter" />    </p>    }

A basic query function is implemented.
