Question

我正在我的asp.net应用程序中实现URL Routing，因为我的一些规则是冲突的。下面是我的一些相互矛盾的规则：

RouteTable.Routes.Add("QuestionSubject",
    new Route("questions/{subjectname}/{pageno}",
    new RouteValueDictionary { { "pageno", null } },
    new RouteValueDictionary { { "pageno", @"^[0-9]*$" } },
    new EventRouteHandler("~/questionsitemap/subject.aspx")));

RouteTable.Routes.Add("QuestionSubjectTopic",
    new Route("questions/{subjectname}/{topicname}/{pageno}",
    new RouteValueDictionary { { "pageno", null } },
    new RouteValueDictionary { { "pageno", @"^[0-9]*$" } },
    new EventRouteHandler("~/questionsitemap/topic.aspx")));

RouteTable.Routes.Add("QuestionGrade",
    new Route("questions/{gradename}/",
    new EventRouteHandler("~/questionsitemap/grade.aspx")));

RouteTable.Routes.Add("QuestionSubjectGrade",
    new Route("questions/{gradename}/{subjectname}/",
    new EventRouteHandler("~/questionsitemap/grade.aspx")));

RouteTable.Routes.Add("QuestionSubjectTopicGrade",
    new Route("questions/{gradename}/{subjectname}/{topicname}/",
    new EventRouteHandler("~/questionsitemap/grade.aspx")));

当我请求打开 QuestionGrade 规则时，它正在调用 QuestionSubject ，因为两者的规则相似，其他规则也是如此。

请任何人帮我找到解决方案。

由于路由引擎无法区分{subjectname}和{gradename}，因此您需要使它们更具体。您可以使用以下内容，为您的路线添加/subject/和/grade/吗？

RouteTable.Routes.Add("QuestionSubject",
    new Route("questions/subject/{subjectname}/{pageno}",
    new RouteValueDictionary { { "pageno", null } },
    new RouteValueDictionary { { "pageno", @"^[0-9]*$" } },
    new EventRouteHandler("~/questionsitemap/subject.aspx")));

RouteTable.Routes.Add("QuestionGrade",
    new Route("questions/grade/{gradename}/",
    new EventRouteHandler("~/questionsitemap/grade.aspx")));
