解决。指向所有不存在的网址你的错误页面，请执行以下操作：

Solved. To point all non-existing urls to your error page, do the following:

• 添加低于code。在您的RouteConfig.cs文件的末尾：

• Add the code below at the end of your RouteConfig.cs file:

public static void RegisterRoutes(RouteCollection routes)
{
    // Default
    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );

    // Add this code to handle non-existing urls
    routes.MapRoute(
        name: "404-PageNotFound",
        // This will handle any non-existing urls
        url: "{*url}",
        // "Shared" is the name of your error controller, and "Error" is the action/page
        // that handles all your custom errors
        defaults: new { controller = "Shared", action = "Error" }
    );
}

<configuration>
    <system.webServer>
       <modules runAllManagedModulesForAllRequests="true"></modules>
    </system.webServer>

    <system.web>
       <httpRuntime relaxedUrlToFileSystemMapping="true" />
    </system.web>
</configuration>

这应该指向所有的不存在的网址，如（/ad/asd/sa/das,d/asd,asd.asd+dpwd'=12=2e-21）到你的错误页面。

That should point all the non-existing urls such as (/ad/asd/sa/das,d/asd,asd.asd+dpwd'=12=2e-21) to your error page.
