Html.ActionLink只支持文字链接，现在我们利用C#的扩展方法写一个Html.ActionLinkWithImage()让其支持图片链接的功能。
一、首先新建一个静态类，将命名空间在改在System.Web.Mvc下，代码如下
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace System.Web.Mvc { public static class MyHelpler { public static MvcHtmlString ActionLinkWithImage(this HtmlHelper html, string imgSrc, string actionName) { 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); TagBuilder tagBuilder = new TagBuilder("a") { InnerHtml = img }; tagBuilder.MergeAttribute("href", url); return new MvcHtmlString(tagBuilder.ToString(TagRenderMode.Normal)); } public static MvcHtmlString ActionLinkWithImage(this HtmlHelper html, string imgSrc, string actionName,string controllerName,object routeValue=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, controllerName, routeValue); TagBuilder tagBuilder = new TagBuilder("a") { InnerHtml = img }; tagBuilder.MergeAttribute("href", url); return new MvcHtmlString(tagBuilder.ToString(TagRenderMode.Normal)); } } }
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})
MVC的带链接的图片标签就完成了，可以传入跳转到制定的控制器、方法、以及传入参数等。
MVC 自定义标签,给Html.ActionLink加上支持图片链接的功能
