请教VB.net里.xaml页面之间跳转方法

[zhabu]

那位朋友知道Silverlight中怎么样在两个.xaml页面之间跳转。
这两天一直在查资料但是都是C#的程序没有VB的！

VB和C#是一样的只是语法不同。

在App.xaml中

        Dim pager As New PageNavigator()
        Me.RootVisual = pager
        Navigator.pager = pager
        Navigator.Switch(New Login())

PageNavigator.xaml.vb

Partial Public Class PageNavigator
    Inherits UserControl

    Public Sub New 
        InitializeComponent()
    End Sub

    Public Sub Navigate(ByVal nextPage As UserControl)
        Me.Content = nextPage
    End Sub

    Public Sub Navigate(ByVal nextPage As UserControl, ByVal state As Object)
        Me.Content = nextPage
        Dim nav As INavigator = TryCast(nextPage, INavigator)
        If nav IsNot Nothing Then
            nav.UtilizeState(state)
        Else
            Throw New ArgumentException("nextPage cannot be found! " & nextPage.Name.ToString())
        End If
    End Sub
End Class

Navigator.vb

Public NotInheritable Class Navigator

    Public Shared pager As PageNavigator

    Private Sub New()
    End Sub

    Public Shared Sub Switch(ByVal newPage As UserControl)
        pager.Navigate(newPage)
    End Sub

    Public Shared Sub Switch(ByVal newPage As UserControl, ByVal state As Object)
        pager.Navigate(newPage, state)
    End Sub

End Class

INavigator.vb

Public Interface INavigator
    Sub UtilizeState(ByVal state As Object)
End Interface
