VC3自定义标签,给ajax.Action和Html.ActionLink加上支持图片链接的功能，添加了htmlAttributes

 //ajax.Action加图片
public static MvcHtmlString AjaxActionWithImage(this AjaxHelper html, string imgSrc, string actionName, object routeValue = null, AjaxOptions ajaxOptions = null)
{
var urlHelper = new UrlHelper(html.ViewContext.RequestContext);

string imgUrl = urlHelper.Content(imgSrc);
TagBuilder imgTagBuilder = new TagBuilder("img");
imgTagBuilder.MergeAttribute("src", imgUrl);
string img = imgTagBuilder.ToString(TagRenderMode.SelfClosing);
string url = urlHelper.Action(actionName, urlHelper.RequestContext.RouteData.Values["controller"].ToString(), routeValue);

TagBuilder tagBuilder = new TagBuilder("a")
{
InnerHtml = img
};

tagBuilder.MergeAttribute("href", url);
tagBuilder.MergeAttributes((ajaxOptions ?? new AjaxOptions()).ToUnobtrusiveHtmlAttributes());
return new MvcHtmlString(tagBuilder.ToString(TagRenderMode.Normal));
}
