这是我的,它的核心功能是做一些重载

public static string ImageLink(this HtmlHelper htmlHelper, string imgSrc, string alt, string actionName, string controllerName, object routeValues, object htmlAttributes, object imgHtmlAttributes)
{
    UrlHelper urlHelper = ((Controller)htmlHelper.ViewContext.Controller).Url;
    string imgtag = htmlHelper.Image(imgSrc, alt,imgHtmlAttributes);
    string url = urlHelper.Action(actionName, controllerName, routeValues);

    TagBuilder imglink = new TagBuilder("a");
    imglink.MergeAttribute("href", url);
    imglink.InnerHtml =imgtag;
    imglink.MergeAttributes(new RouteValueDictionary(htmlAttributes), true);

    return imglink.ToString();
}

这是我从上面的MiniScalope答案中获得的更新版本。我正在使用 VS2010 和 ASP.Net MVC 2 预览版

        public static string ImageLink(this HtmlHelper htmlHelper, string imgSrc, string alt, string actionName, string controllerName, object routeValues, object htmlAttributes, object imgHtmlAttributes)
    {
        UrlHelper urlHelper = ((Controller)htmlHelper.ViewContext.Controller).Url;
        TagBuilder imgTag = new TagBuilder("img");
        imgTag.MergeAttribute("src", imgSrc);
        imgTag.MergeAttributes((IDictionary<string, string>) imgHtmlAttributes,true);
        string url = urlHelper.Action(actionName, controllerName, routeValues);



        TagBuilder imglink = new TagBuilder("a");
        imglink.MergeAttribute("href", url);
        imglink.InnerHtml = imgTag.ToString();
        imglink.MergeAttributes((IDictionary<string, string>)htmlAttributes, true);

        return imglink.ToString();

    }

<%= Html.ActionLink(Html.Image(imageUrl, imageAlt), actionName, controllerName) %>

可以工作,图像扩展来自期货大会。或者自己做扩展。

创建您自己的辅助扩展。

public static string Image(this HtmlHelper helper, string src, string alt)
{
    TagBuilder tb = new TagBuilder("img");
    tb.Attributes.Add("src", helper.Encode(src));
    tb.Attributes.Add("alt", helper.Encode(alt));
    return tb.ToString(TagRenderMode.SelfClosing);
}

我没有足够的自信来添加评论,但这是对 上面 MiniScalope 评论的评论

UrlHelper urlHelper = ((Controller)htmlHelper.ViewContext.Controller).Url;

我建议将其作为 HtmlHelper 扩展方法本身(并简化它),以便重用:

private static UrlHelper Url(this HtmlHelper helper)
{ 
  return new UrlHelper(helper.ViewContext.RequestContext);
}

此代码已在 mvc4 上测试...

    public static MvcHtmlString ImageLink(this HtmlHelper htmlHelper, string imgSrc, string alt, string actionName, string controllerName, object routeValues, object htmlAttributes, object imgHtmlAttributes)
    {
        UrlHelper urlHelper = ((Controller)htmlHelper.ViewContext.Controller).Url;
        var imgTag = new TagBuilder("img");
        imgTag.MergeAttribute("src", imgSrc);
        imgTag.MergeAttributes((IDictionary<string, string>)imgHtmlAttributes, true);
        string url = urlHelper.Action(actionName, controllerName, routeValues);



        var imglink = new TagBuilder("a");
        imglink.MergeAttribute("href", url);
        imglink.InnerHtml = imgTag.ToString();
        imglink.MergeAttributes((IDictionary<string, string>)htmlAttributes, true);

        return MvcHtmlString.Create(imglink.ToString());

    }
