RouteData.Values 保持为空 [英] RouteData.Values stays Empty

问题描述

我的路线代码如下所示:

My Code for the Route looks like this:

 RouteTable.Routes.MapPageRoute("IDP", "Person/{IDP}", "~/Person.aspx")

现在我想获取表单上的数据，通常它是这样工作的:

And now i want to get the Data on a Form, normally it works like this:

int id = Convert.ToInt32(Page.RouteData.Values["IDP"]);

但每次我尝试从路线获取数据时，例如:http://PC-81/SkillDatenbank/Person/1我从值中没有得到任何数据(它是空的！)

But everytime i try to get the Data from the Route e.g.: http://PC-81/SkillDatenbank/Person/1 I get no Data from the Value (it is empty!)

我将 ASP.Net 4.5 与 Web 窗体一起使用.我创建了一个新项目并进行了测试，但它也不起作用我究竟做错了什么?在上一个项目中它确实是这样工作的:(你能帮我吗?

I am using ASP.Net 4.5 with Web Forms. I made an new Project and tested and it didnt work either What am i Doing wrong? in the Last Project it did work like this :( Can you help me?

推荐答案

您的问题可能出在您的路由表中.我创建了一个 WebForms 项目来对此进行测试.

Your problem ist probably located in your Routing table. I have created a WebForms project to test this out.

打开您的 Global.asax(或您存储 RouteConfig 的任何位置；默认为 App_Start/RouteConfig.cs)并检查您的 RegisterRoutes 方法.向其中添加以下行(如果尚不存在).

Open up your Global.asax (or whereever you store your RouteConfig; default is App_Start/RouteConfig.cs) and check your RegisterRoutes method. Add the following line to it, if it isn't already present.

void RegisterRoutes(RouteCollection routes)
{
    var settings = new FriendlyUrlSettings();
    settings.AutoRedirectMode = RedirectMode.Permanent;
    routes.EnableFriendlyUrls(settings);

    /* ... additional routes */
    routes.MapPageRoute("","Person/{IDP}", "~/Person.aspx");
}

在您的 Application_Start 中应该有这样一行，如果您使用 App_Start 文件夹中的默认配置:RouteConfig.RegisterRoutes(RouteTable.Routes);

In your Application_Start there should be a line like this, if you use the default configuration with in the App_Start folder: RouteConfig.RegisterRoutes(RouteTable.Routes);

如果您在 global.asax.cs 中定义了路由，则它只是 RegisterRoutes(RouteTable.Routes);

If you defined your routes in your global.asax.cs it is just RegisterRoutes(RouteTable.Routes);

如果您现在通过 http://PC-81/SkillDatenbank/Person/1 访问您的主页，RouteData 字典将包含 1 组数据，如下所示:

If you now access your Page via http://PC-81/SkillDatenbank/Person/1 the RouteData dictionary will contain 1 set of data, like this:
