ASP.NET 路由。如何在通用处理程序中使用路由？

Question

我尝试在以下通用处理程序中使用 ASP.Net，但在 Page.RouteData 处收到此错误

Reference to a non-shared member requires an object reference

我做错了什么？

<%@ WebHandler Language="VB" Class="MainHandler" %>

Imports System
Imports System.Web
Imports System.Xml


    Public Class MainHandler : Implements IHttpHandler, System.Web.SessionState.IRequiresSessionState

        Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

            Dim lng As String = Page.RouteData.Values("locale")

        End Sub

        Public ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
            Get
                Return False
            End Get
        End Property

    End Class

对于任何答案，请记住我是一个新手，我的语言是 VB.NET :) 先感谢您。

Answer 1

 Dim lng As String = HttpContext.Current.Request.RequestContext.RouteData.Values("locale")

Answer 2

请尝试以下操作。您必须检索路由表并从中读取。

Dim rd AS RouteData
rd = RouteTable.Routes.GetRouteData(new HttpContextWrapper(context))

Dim val AS String
val = rd.Values["locale"].ToString()
