基于查询字符串 ID 的 ASP.net URL 重写

Question

大家好，我想弄清楚如何将诸如 www.mywebsit.com/Articles/newsInfo.aspx?id=3 之类的 URL 重新写入 www.mywebisite.com/Articles/My-News-Title.aspx

我不知道我是否误解了某些东西，但下面是我拥有的代码，似乎没有发生任何事情。 URL 保持不变。

Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
    Dim currPath As String = Request.Url.ToString

    If currPath.IndexOf("Articles") <> -1 And currPath.IndexOf("?np=") <> -1 Then
        currPath = currPath.Substring(currPath.IndexOf("?np=") + 4)
        Dim connectionString As String = ConfigurationManager.ConnectionStrings("MyConString").ConnectionString
        Dim myreader As System.Data.SqlClient.SqlDataReader
        Using myConnection As New System.Data.SqlClient.SqlConnection(connectionString)
            Try
                myConnection.Open()
                Dim myCommand As New System.Data.SqlClient.SqlCommand()


                myCommand.CommandType = Data.CommandType.Text
                myCommand.CommandText = "SELECT TheNewsTitle FROM TheNews WHERE TheNewsId=" & currPath.Replace("'", "''")
                myCommand.Connection = myConnection

                myreader = myCommand.ExecuteReader
                If myreader.HasRows Then
                    myreader.Read()
                    HttpContext.Current.RewritePath("~/Articles/" & myreader.GetValue(0).ToString.Replace(" ", "-") & ".aspx")
                    myreader.Close()

                End If

                myConnection.Close()
                myCommand.Dispose()
                myConnection.Dispose()

            Catch ex As Exception
                myConnection.Close()
                myConnection.Dispose()
            End Try
        End Using
    End If
End Sub

代码永远不会出错，所以我不明白发生了什么。

您是否正在尝试进行实际的 URL 重写？换句话说 - 您希望您网站中的链接看起来像

www.mywebsite.com/Articles/My-News-Title.aspx

并被处理

www.mywebsite.com/Articles/newsInfo.aspx?id=3

是吗？
