asp.net mvc3: How to return raw html to view?

Are there other ways I can return raw html from controller? As opposed to just using viewbag. like below:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        ViewBag.HtmlOutput = "<HTML></HTML>";
        return View();
    }
}

@{
    ViewBag.Title = "Index";
}

@Html.Raw(ViewBag.HtmlOutput)

What was working for me (ASP.NET Core), was to set return type ContentResult, then wrap the HMTL into it and set the ContentType to "text/html; charset=UTF-8". That is important, because, otherwise it will not be interpreted as HTML and the HTML language would be displayed as text.

Here's the example, part of a Controller class:

/// <summary>
/// Startup message displayed in browser.
/// </summary>
/// <returns>HTML result</returns>
[HttpGet]
public ContentResult Get()
{
    var result = Content("<html><title>DEMO</title><head><h2>Demo started successfully."
      + "<br/>Use <b><a href=\"http://localhost:5000/swagger\">Swagger</a></b>"
      + " to view API.</h2></head><body/></html>");
    result.ContentType = "text/html; charset=UTF-8";
    return result;
}

In controller you can use MvcHtmlString

public class HomeController : Controller
{
    public ActionResult Index()
    {
        string rawHtml = "<HTML></HTML>";
        ViewBag.EncodedHtml = MvcHtmlString.Create(rawHtml);
        return View();
    }
}

In your View you can simply use that dynamic property which you set in your Controller like below

<div>
        @ViewBag.EncodedHtml
</div>

Give a try to return bootstrap alert message, this worked for me

return Content("<div class='alert alert-success'><a class='close' data-dismiss='alert'>
&times;</a><strong style='width:12px'>Thanks!</strong> updated successfully</div>");

Note: Don't forget to add bootstrap css and js in your view page

hope helps someone.

Simply create a property in your view model of type MvcHtmlString. You won't need to Html.Raw it then either.

There's no much point in doing that, because View should be generating html, not the controller. But anyways, you could use Controller.Content method, which gives you ability to specify result html, also content-type and encoding

public ActionResult Index()
{
    return Content("<html></html>");
}

Or you could use the trick built in asp.net-mvc framework - make the action return string directly. It will deliver string contents into users's browser.

public string Index()
{
    return "<html></html>";
}

In fact, for any action result other than ActionResult, framework tries to serialize it into string and write to response.

That looks fine, unless you want to pass it as Model string

public class HomeController : Controller
{
    public ActionResult Index()
    {
        string model = "<HTML></HTML>";
        return View(model);
    }
}

@model string
@{
    ViewBag.Title = "Index";
}

@Html.Raw(Model)
