Question

现在我有一个基本程序。我刚刚开始自学C＃，我不知道如何进入一个新页面，我可以在其上添加更多按钮和文本等。

这是我到目前为止所做的：

namespace HelloWorld
{
    /// <summary>
    /// An empty page that can be used on its own or navigated to within a Frame.
    /// </summary>
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            this.InitializeComponent();
            this.Next.Visibility = Visibility.Collapsed;
        }

        private void ClickMe_Click(object sender, RoutedEventArgs e)
        {
            this.HelloMessage.Text = "This is a test message deployed from Rohan's PC.";
            this.ClickMe.Visibility = Visibility.Collapsed;
            this.Next.Visibility = Visibility.Visible;
        }
        private void Next_Click(object sender, RoutedEventArgs e)
        {
            this.Next.Visibility = Visibility.Collapsed;
            this.HelloMessage.Visibility = Visibility.Collapsed;
        }
    }
}

这是我在Raspberry Pi 3b上运行的程序。到目前为止它一切正常但我想知道如何添加更多页面。非常感谢帮助。

Answer 1

此解决方案基于WPF（Windows Presentation Foundation）C＃。

假设您有3个需要导航的页面，请将它们称为Page1，Page2，Page3 在我们添加页面之前，我们可以设置框架来保存这些页面。

<强> MainWindow.XAML

    <Grid>
        <Frame x:Name="WizardWindowFrame" Content="" NavigationUIVisibility="Hidden" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>

    </Grid>

代码背后：MainWindow.XAML.CS

public MainWindow()
        {
            InitializeComponent();
         Title title = new Title(); // Navigate to Page1
         WizardWindowFrame.NavigationService.Navigate(title);


      }

注意：因此，当您的应用程序运行时，您将看到它从Page1和第1页上运行，您有一个下一步按钮。在我们定义三个页面之前，我们需要从Solution explorer（Ctrl + Shift + A）

添加它们

代码背后：Title.XAML.CS

   public partial class Title : Page
   {
      public Title()
      {
         InitializeComponent();

      }
public void TitleButtonNext_Click(object sender, EventArgs e)
      {


       Middle middle = new Middle(); // Navigate to Page 2 on click
       this.NavigationService.Navigate(new Uri("Middle.xaml", UriKind.Relative));


      }
}

代码背后：Middle.XAML.CS

 public partial class Middle: Page
   {
      public Middle()
      {
         InitializeComponent();

      }
public void MiddleButtonNext_Click(object sender, EventArgs e)
      {


       Final final = new Final(); // Navigate to Page 3 on click
       this.NavigationService.Navigate(new Uri("Final.xaml", UriKind.Relative));


      }
  }

代码背后：Final.XAML.CS

 public partial class Final: Page
   {
      public Final()
      {
         InitializeComponent();

      }
public void FinishButtonBack_Click(object sender, EventArgs e)
      {

      Middle middle = new Middle(); 
      this.NavigationService.Navigate(middle); //Goes to the previous page

      }
  }

输出

根据我的要求修改了页面。但上面的属性用于创建裸骨

互联网上有大量的信息，我已经为我的一些收藏书添加了书签，这可以帮助你做出决定。

但我建议您更熟悉C＃，然后参考文档
