Turn off HTML Encoding in Razor

asp.net-mvc razor html-encode

I have a function that returns a snippet of JavaScript and/or HTML.

static public string SpeakEvil()
{
    return "<script>alert('BLAH!!');</script>";
}

In the view, Razor is quite rightly HTML encoding it, as most would expect. 

@StaticFunctions.SpeakEvil()

How do I have Razor not HTML Encode this, so that the HTML and JavaScript are emitted verbatim, and that any script actually runs?

You could use the Raw() function but it's mostly meant for things that come from the database.

For a helper like you have I would suggest returning an IHtmlString:

static public IHtmlString SpeakEvil() {
    return new HtmlString("<script>alert('BLAH!!');</script>");
}

That way you don't have have to call Raw() at every callsite.
