11 {
12 var urlHelper = new UrlHelper(html.ViewContext.RequestContext);
13
14 string imgUrl = urlHelper.Content(imgSrc);
15 TagBuilder imgTagBuilder = new TagBuilder("img");
16 imgTagBuilder.MergeAttribute("src", imgUrl);
17 string img = imgTagBuilder.ToString(TagRenderMode.SelfClosing);
18
19 string url = urlHelper.Action(actionName);
20
21 TagBuilder tagBuilder = new TagBuilder("a")
22 {
23 InnerHtml = img
24 };
25 tagBuilder.MergeAttribute("href", url);
26
27 return new MvcHtmlString(tagBuilder.ToString(TagRenderMode.Normal));
28 }
29 public static MvcHtmlString ActionLinkWithImage(this HtmlHelper html, string imgSrc, string actionName,string controllerName,object routeValue=null)
30 {
31 var urlHelper = new UrlHelper(html.ViewContext.RequestContext);
32
33 string imgUrl = urlHelper.Content(imgSrc);
34 TagBuilder imgTagBuilder = new TagBuilder("img");
35 imgTagBuilder.MergeAttribute("src", imgUrl);
36 string img = imgTagBuilder.ToString(TagRenderMode.SelfClosing);
37
38 string url = urlHelper.Action(actionName, controllerName, routeValue);
39
40 TagBuilder tagBuilder = new TagBuilder("a")
41 {
42 InnerHtml = img
43 };
44 tagBuilder.MergeAttribute("href", url);
45
46 return new MvcHtmlString(tagBuilder.ToString(TagRenderMode.Normal));
47 }
48 }
49 }
二、在view下使用：
@Html.ActionLinkWithImage(Url.Content("~/Content/images/index_1.gif"), "Index") @Html.ActionLinkWithImage(Url.Content("~/Content/images/index_2.gif"), "List","Admin", new { id=1}) 出处：http://www.bbsmvc.com/mvclearn/thread-30-1-1.html
