如何从代码隐藏（aspx.vb）到.aspx上的Dim变量获取Id

Question

我有一个带有变量的aspx.vb背后的代码。

我想在.aspx网页上使用它。

例如。

Public Class proventos_rendimento_distribuicoes_amortizacoes
    Inherits System.Web.UI.Page

    Dim id_to_use As String = ""

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Me.IsPostBack Then
            lblCustomerId.Text = Me.Page.RouteData.Values("nome_artigo").ToString()
            id_to_use = Me.Page.RouteData.Values("nome_artigo").ToString()
        End If
    End Sub
End Class

我希望在.aspx上使用它与<％= id_to_use％>之类的东西

EG

<b>Customer Id:</b>
<asp:Label ID="lblCustomerId" runat="server" />
<br />
<b><%= id_to_use %></b>

但这不起作用。

有可能吗？

只需要将Dim id_to_use As String =“”声明为public：

public Dim id_to_use As String = ""

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        lblCustomerId.Text = Me.Page.RouteData.Values("nome_artigo").ToString()
        id_to_use = Me.Page.RouteData.Values("nome_artigo").ToString()
    End If
End Sub
