C# 在WPF C中发送值时无法从一页转到新页#

在我的MainWindow.xaml.cs中，我使用以下命令打开一个新页面（PkmnSelect）：

PkmnSelect pkmnSelect = new PkmnSelect(); 
Content = pkmnSelect;

然后，一旦用户在此页面（PkmnSelect）中选择了他们的神奇宝贝团队，他们就可以单击开始。“开始”按钮具有以下代码：

Battle battle = new Battle(userPokemon, opponentPokemon);
Content = battle;

Battle是一个我想将两个神奇宝贝[]作为输入的页面，因此我在Battle中创建了一个额外的构造函数，如下所示：

public Battle(Pokemon[] userPkmn, Pokemon[] opponentPkmn) : this()
{
    userPokemon = userPkmn;
    opponentPokemon = opponentPkmn;
}

这给了我一个错误：“页面只能将窗口或框架作为父对象。”

我的问题是，将值从一个页面发送到另一个页面的正确方式是什么？ 我到处都找过了，我试过的都没用

编辑：Battle.xaml.cs的开始：

public partial class Battle : Page
{
    Pokemon[] userPokemon;
    Pokemon[] opponentPokemon;

    public Battle()
    {
        InitializeComponent();
        //Some code to hide some xaml stuff and start some music
    }

    public Battle(Pokemon[] userPkmn, Pokemon[] opponentPkmn) : this()
    {
        userPokemon = userPkmn;
        opponentPokemon = opponentPkmn;
    }

在

页面

中不能有

页面

相反，您应该让它们的公共父组件使用事件处理转换：

public class Pokemon
{
    public string Name { get; set; }
}

你能显示战斗代码吗？当然@尼古拉斯下面的代码是战斗的开始，除了剩下的方法@Nikolaus我也在问题中发布了它（不适合评论），我会尽快尝试！谢谢我对此解决方案有问题：我的主窗口显示以下错误：“PokemonSelected”成员无法识别或无法访问。我一直在阅读，人们都在谈论将任何CPU更改为x86的事情。。。我应该怎么做？这只是一个设计时错误，还是在运行时有问题？这很有效！这个错误只是设计时的错误，一旦我试着运行它，它就消失了。我想现在一切都好了。我将继续我的代码工作，并让你知道如果一切顺利！谢谢你，muchI并没有这么做，因为我的课程有点不同，但一切都很好。谢谢
