Answer 1

尝试这个

 NavigationService.Navigate(new Uri("/Organization_Details.xaml?selectedItem=" +Organization.Name , UriKind.Relative));

您在 url 的开头错过了“/” ，在 selectedItem 之后错过了“=”

Answer 2

不能直接取值，所以使用下面的函数，

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
    {
        base.OnNavigatedTo(e);
            if (e.Uri.OriginalString.Contains("selectedItem"))
            {
                //Get the value here
            }
     }

这对你来说很好！
