如何使用c＃在textblock定义的xaml中设置文本。我正在重定向到一个电话页面，里面有一个堆叠面板和几个文本块。如果我命名一个文本块并在c＃代码中调用它，它就不起作用了。如何在加载页面时在文本块中设置字符串...并从上一页传递文本。基本上文本块无法识别......如何在c＃代码中显示它...

XAML：

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="16,0,12,0">
    <StackPanel x:Name="activationPanel" Margin="0,10">
        <TextBlock TextWrapping="Wrap" Text="Almost there !" FontFamily="Segoe UI" FontWeight="Light" FontSize="24" Foreground="#FF486070"/>
        <TextBlock TextWrapping="Wrap" Text="An activation mail has been sent" FontFamily="Segoe UI" FontWeight="Light" FontSize="24" Foreground="#FF486070" Margin="0,18,0,0"/>
        <TextBlock Name="useremail" TextWrapping="Wrap" FontFamily="Segoe UI" FontWeight="SemiBold" FontSize="24" Foreground="#FF486070" Margin="0,10,0,0" LostFocus="useremail_LostFocus"/>
        <TextBlock TextWrapping="Wrap" Text="please click on the link to activate your account" FontFamily="Segoe UI" FontWeight="Light" FontSize="24" Foreground="#FF486070" Margin="0,50,78,0"/>
        <Button x:Name="btnAcA" Content="ACCOUNT ACTIVATED" Width="335" HorizontalAlignment="Left" Height="42" Padding="12,0,10,0" Background="#FF55D782" BorderBrush="{x:Null}" BorderThickness="0" FontSize="16" FontFamily="Segoe UI" Style="{StaticResource LoginButtonStyle}" Margin="0,90,0,25" Click="btnAcA_Click"/>
        <Button x:Name="btnRAM" Content="RESEND ACTIVATION MAIL" Width="335" HorizontalAlignment="Left" Height="42" Padding="12,0,10,0" Background="#FF637A8A" BorderBrush="{x:Null}" BorderThickness="0" FontSize="16" FontFamily="Segoe UI" Style="{StaticResource LoginButtonStyle}" Margin="0,0,0,25"/>
    </StackPanel>
</Grid>

C＃：

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
    base.OnNavigatedTo(e);
    string email=null;
    if (this.NavigationContext.QueryString.ContainsKey("email"))
    {
        email = this.NavigationContext.QueryString["email"];
    }

    Debug.WriteLine(email);
    setTextBoxValue(email);
}

private void setTextBoxValue(string email)
{
    //TextBlock useremail = new TextBlock();
    useremail.Text = email;
}
