Question

我一直致力于克隆砖块，以便在C＃中获得更好的效果，但不断出现此错误 “错误1'WPFGame1.Gammer'不包含'Window_KeyDown'的定义，并且没有可以找到接受类型'WPFGame1.Gammer'的第一个参数的扩展方法'Window_KeyDown'（你是否缺少using指令或汇编引用？）” 它是一个WPF，我在课堂上声明了它有很多无用的CS你不需要，但我只是希望一切都在那里，以防你需要别的东西。这是相关的XAML

<Window x:Class="WPFGame1.Gammer" Name="myWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    WindowStyle="None"
    AllowsTransparency="True"
    ResizeMode="CanMinimize"
    Title="Brick Breaker" Height="650" Width="700" 
    KeyDown="Window_KeyDown" <!--error occurs here-->
    WindowStartupLocation="CenterScreen" 
    >

和CS

public class Gammer : Window, IComponentConnector{
   private void Window_KeyDown(object sender, KeyEventArgs e)
        {
            if (Gammer.movingTimer.IsEnabled && e.Key == Key.Space)
            {
                Gammer.movingTimer.Stop();
                Pause p = new Pause(this);
                p.ShowDialog();
            }
            Key key = e.Key;
            if (key <= Key.F)
            {
                switch (key)
                {
                    case Key.Left:
                        {
                            double leftRed = Canvas.GetLeft(this.rectangleRed);
                            if (leftRed > 0.0)
                            {
                                Canvas.SetLeft(this.rectangleRed, leftRed - 20);
                                return;

Answer 1

public class Gammer : Window, IComponentConnector{

尝试将其切换到此

public partial class Gammer : Window, IComponentConnector{

没有类的定义，也找不到参数c＃
