Question

在MainWindow.xaml.cs中，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;

战斗是我想将两个Pokémon[]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;
}

这给了我错误“页面只能将Window或Frame作为父级。”

我的问题是，将值从一页发送到另一页的正确方法是什么？我到处都看过，没有尝试过。

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;
    }

Answer 1

$(document).ready(function() { $('#members').DataTable( { "scrollX": true } ); } );中不能有Page。

相反，您应该让它们的公共父组件使用事件：

Page ：

Pokemon

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