Razor directive to prevent element rendering-CodePudding

I search for an option to render some div-tags in my cshtml files with razor conditionally like the angular directive ng-if. Normally I write code like

@if (mycond) {
  <div>blub</div>
}

And I search for a more readable approach like

  <div asmarttag:mycond>blub</div>

Is there any option to achieve that?

Not sure if it's exactly what you want... but what about a custom HTMLHelper?

namespace System.Web.Mvc
{
    public static class CustomHTMLHelpers
    {
        public static IHtmlString Render(this HtmlHelper helper, bool render, string html)
        {

            if (render)
            {
                return helper.Raw(html);
            }
            else
            {
                return new HtmlString("");
            }

        }

    public static IHtmlString Render(this HtmlHelper helper, bool render, MvcHtmlString html)
    {

        if (render)
        {
            return html;
        }
        else
        {
            return new HtmlString("");
        }

    }

}

Then you could do:

@Html.Render(mycond, "<div>blub</div>")

@Html.Render(true, @Html.ActionLink("Home", "Index", "Home"))

Would certinly turn it into a one liner for you.
