mvc，超链接除了直接写在a标签的href内还可以使用路由规则来生成，这样在改变了路由规则或者路由名称时不用再去代码中更改href的值，而且还容易遗漏。借助Url.RouteUrl或者Html.RouteLink就可以轻松实现，再以后的改变中将不用再去理会路由规则的改变而带来的工作量。

路由规则：

//bubuko测试
routes.MapRoute("bubuko_1", "{controller}-{action}-{eID}-{pageIndex}.html",
                new { controller = "abc", action = "Index" });

//bubuko测试
routes.MapRoute("bubuko_2", "{action}-{eID}-{pageIndex}.html",
                new { controller = "abc", action = "Index" });

cshtml中代码：

Url.RouteUrl方式，路由名称是“bubuko_1”：@Url.RouteUrl("bubuko_1", new { eID = ViewBag.eID, pageIndex = ViewBag.pageIndex })
<br />
Url.RouteUrl方式，路由名称是“bubuko_2”：@Url.RouteUrl("bubuko_2", new { eID = ViewBag.eID, pageIndex = ViewBag.pageIndex })

<br />
<br />

Html.RouteLink方式，路由名称是“bubuko_1”：@Html.RouteLink("bubuko.com分享超链接", "bubuko_1", new { eID = ViewBag.eID, pageIndex = ViewBag.pageIndex }, new { id = "abc" })
<br />
Html.RouteLink方式，路由名称是“bubuko_2”：@Html.RouteLink("bubuko.com分享超链接", "bubuko_2", new { eID = ViewBag.eID, pageIndex = ViewBag.pageIndex }, new { id = "abc" })

显示效果，html代码：

Url.RouteUrl方式，路由名称是“bubuko_1”：/abc-abclist-10-12.html
<br />
Url.RouteUrl方式，路由名称是“bubuko_2”：/abclist-10-12.html

<br />
<br />

Html.RouteLink方式，路由名称是“bubuko_1”：<a href="/abc-abclist-10-12.html" id="abc">bubuko.com分享超链接</a>
<br />
Html.RouteLink方式，路由名称是“bubuko_2”：<a href="/abclist-10-12.html" id="abc">bubuko.com分享超链接</a>
