传统式
href直接跟链接地址URL
<a href="@Model.Base.BdtUrl" target="_blank">首页</a>><span>发布问题</span>
URL路由式@Url.RouteUrl
使用路由名称为指定的路由值生成完全限定URL
<a href="@Url.RouteUrl("Detail", new { id = topicModel.LT_ID })" target="_blank">@topicModel.LT_Title</a></li>
MVC路由超链接标签@Html.Routelink
@Html.RouteLink("精选酒店", "ProductListPage", new { cityID = Model.CurrentCityID, productType = ProductType.Hotel }, new { @class = (Model.ProductTypeSelected == ProductType.Hotel ? "current" : "") })
