在WP7跳转时（传递多个参数，可以用&来连接URL地址）:

  this.NavigationService.Navigate(new Uri("NewPage.xaml?Account=CCTV", UriKind.Relative));

在NewPage.Xaml.cs当中重写OnNavigatedTo方法

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
         {
string value = string.Empty;
             IDictionary<string, string> queryString = this.NavigationContext.QueryString;
if (queryString.ContainsKey("Account"))
             {
                 txtAccounts.Text = "账号：" + queryString["Account"];
             }
base.OnNavigatedTo(e);
         }

　　或

  protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
         {
string value = string.Empty;
             IDictionary<string, string> queryString = this.NavigationContext.QueryString;
             queryString.TryGetValue(“Account”, out value);
if (value != null)
             {
                 txtAccount.Text = “账号:"+ value;
             }
base.OnNavigatedTo(e);
         }

　　全局数据方便在任何地址调用：

 PhoneApplicationService.Current.State["Account"] = "CCTV";

if (PhoneApplicationService.Current.State.ContainsKey("Account"))
 {
        txtAccounts.Text = "账号：" + PhoneApplicationService.Current.State["Account"] as string;
 }
