Convert plain text with html tags to html string and render it in Blazor

Sample:

@{     var s = "<p>Sample text</p>"; }

Expectation:

Sample text.

I want it rendered on browser but I couldn't render it. It just outputs the whole value of s as text string. I already try

@(new HtmlString(s))

encoded it with HttpUtility.HtmlEncode and decode it with HttpUtility.HtmlDecode but still no use.
