How to render a self closing tag using TagBuilder?

问题

The following code:

var canonical = new TagBuilder("link");
canonical.MergeAttribute("rel", "canonical");
canonical.MergeAttribute("href", url);
return new MvcHtmlString(canonical.ToString());

Creates a tag:

<link href="http://local.domain.com/" rel="canonical"></link>

Is it possible to render

<link href="http://local.domain.com/" rel="canonical"/>

instead, using TagBuilder?

回答1:

Have you tried:

canonical.ToString(TagRenderMode.SelfClosing);

回答2:

You can also try.

TagBuilder  tagBuilder = new TagBuilder("link");
tagBuilder.TagRenderMode = TagRenderMode.SelfClosing;
