从Silverlight URL中提取2个值 [英] Extracting 2 values from a Silverlight URL

问题描述

我正在尝试使用Silverlight导航服务从不同的文本框中发送2个值，然后将这些值提取到另一个名为page.xaml的页面上.但是似乎永远都无法奏效，请有人帮忙.

MainPage.xaml代码

Hi, I am trying to use the Silverlight Navigation Service to send 2 values from different text boxes and then extract the values on a different page called page.xaml. However it never seems to work could someone please help.

MainPage.xaml code

private void button1_Click(object sender, RoutedEventArgs e)
       {
           NavigationService.Navigate(new Uri("/page.xaml?msg=" + textBox1.Text + "msg2=" + textBox2.Text, UriKind.Relative));
       }

page.xaml代码

page.xaml code

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
     {

         base.OnNavigatedTo(e);

         string msg = "";

         string msg2 = "";

         if (NavigationContext.QueryString.TryGetValue("msg", out msg))
             p1.Text = msg;


        if (NavigationContext.QueryString.TryGetValue("msg2", out msg2))
           p2.Text = msg2;


     }

推荐答案

，您需要使用&"
分隔查询字符串
例如?q1 = v1&q2 = v2&q3 = v3"

you need to separate your query strings by "&"

for example "?q1=v1&q2=v2&q3=v3"
