当我们在 ASP.NET 4 Beta 1 中加入网络形式路径时, 我们没有机会加入一些方法,

注:以下代码与我们添加的ASP.NET 4Beta 2的代码 " 类似 " 。 *那,** 代码的质量要高得多,但这只是一个样本!

那么,你如何使用这些方法?

这些扩展增加了一些简单的方法:

绘图绘图

这些方法为界定网络形式路径提供了捷径。

路由集合. MapRoute( 字符串名称、 字符串 URL、 字符串物理文件) ;

例如,绘制您现在可以做的简单路径图 :

路线表. Routes. MappROute (“Production Details Route”、“产品/”、“~/productionDetails.aspx”);

还有几种变量, 允许定义违约等

路由集合. MapRoute( 字符串名称、 字符串 URL、 字符串物理文件、 对象默认) ;

路由集合. MapRoute( 字符名、 字符串 URL、 字符串物理页、 对象默认值、 字符串)[命名空间);

GetoutruutForUrl 配置工具

GetUrlForroute( 字符串路径Name, 路线估价参数) ;

使用一个有特定名称的路线和路由估价词汇, 包含多个参数, 将会给您返回一个包含要使用的 Url 的字符串。 在数据化应用程序中非常有用 !

例如,

<asp:hyperlink ID="HyperLink1" runat="server"  NavigateUrl='<%# Page.GetUrlForRoute("ProductDetailsRoute",new RouteValueDictionary( new {productid= Eval("ProductID")}))%>'  Text="Details"></asp:hyperlink>

GetUrlForROUT( 滚动价位参数) ;

同样的事情,但自动匹配 路线估价参数相对于路线

忽略( 忽略)

允许您定义URL( 用于升级 WebForms Apps ) 。 URL( 可用于升级 WebForms Apps )

路线集合. IgnoreROute( 字符串 URL) ;

路线集合. IgnoreRoute( 字符串 URL, 对象限制);
