从ASP.NET MVC控制器传递HTML到浏览器直接链接不会呈现HTML标签

Question

My HelloWorldController :

public class HelloWorldController : Controller
{
    // GET: /HelloWorld/ 
    public string Index() {
        return "This is my <b>default</b> action...";
    }

    // GET: /HelloWorld/Welcome/ 
    public string Welcome() {
        return "This is the Welcome action method...";
    }
}

Viewing the page on: http://localhost:12121/HelloWorld

It returns:

This is my <b>default</b> action...

Why does it not render the bold tags?

Answer 1

try this :

 public ActionResult Index()
 {
     return Content("This is my <b>default</b> action...");
 }

Answer 2

I don't think you should be passing HTML from controller, you should use cshtml views to render HTML, and rendering different things by passing a model to your view by your controller.

Here is an example of controller method :

public ActionResult Index()
{
    MyModel model = new MyModel()
    {
        Text = "Hello world"
    };

    return this.View(model);
}

Here is an example of cshtml view :

@* This is the model you passed, you must pass the correct path to it's class *@
@model MyApp.Models.MyModel

@* This should render the "Hello world" message *@
@Model.Text

You would need to change the return type to ActionResult and then use Content() and explicitly specify the content type that is being returned so that browser knows it is html and would render it, right know it is returning as Html Encoded string so browser wouldn't render it:

public ActionResult Index() 
{ 
    return Content("This is my <b>default</b> action...", "text/html"); 
}
