Razor and HTML Helpers

Question

I\'m trying to port the old HTML.Image helper, that I\'m sure everyone has used at one point or another, and I\'m having issues. The following compiles fine:

Answer 1

    public static HtmlString Image(this HtmlHelper helper, string id, string url, string alternateText)
    {
        return Image(helper, id, url, alternateText, null);
    }

    public static HtmlString Image(this HtmlHelper helper, string id, string url, string alternateText, object htmlAttributes)
    {
        // Instantiate a UrlHelper 
        var urlHelper = new UrlHelper(helper.ViewContext.RequestContext);

        // Create tag builder
        var builder = new TagBuilder("img");

        // Create valid id
        builder.GenerateId(id);

        // Add attributes
        builder.MergeAttribute("src", urlHelper.Content(url));
        builder.MergeAttribute("alt", alternateText);
        builder.MergeAttributes(new RouteValueDictionary(htmlAttributes));

        // Render tag
        var ret = new MvcHtmlString(builder.ToString(TagRenderMode.SelfClosing));

        return ret;
    }

just like this tested and works perfect. i needed something like this to concatenate the image name form the model thanks.

and this one works too.
