ASP.NET MVC 使用WebForm

// 忽略对 WebForms 路径的路由
routes.IgnoreRoute("WebForms/{subdir}/{page}");

 public class WebFormsRouteHandler:IRouteHandler
 {
    public IHttpHandler GetHttpHandler(RequestContext requestContext)
     {
       
 // 从URL中获取subdir参数
      var  subdir= requestContext.RouteData.GetRequiredString("subdir");

 // 从URL中获取page参数
        var page = requestContext.RouteData.GetRequiredString("page");
        // 创建实例
        // 根据 page 参数拼接成类似/WebForms/account/page.aspx地址来访问WebForms页面
        IHttpHandler hander = BuildManager.CreateInstanceFromVirtualPath("/WebForms/"+subdir+"/"+ this.page+".aspx", typeof(System.Web.UI.Page)) as IHttpHandler;
        return hander;
    }
}
