赢取支票并再次玩C＃字样

Question

我有3个问题：1-第一次按下“ letsPlay”按钮时，无论我在哪里按下，都可以得到oImage，但之后效果很好。 2-Winner（）方法不起作用...它什么也不做。 3-如何重置网格背景，因为我找不到任何结果。

好的，这是xaml代码：

<StackPanel>
    <Grid VerticalAlignment="Top">
        <Button x:Name="letsPlay" Content="Let's Start!" Click="letsPlay_Click"/>
        <TextBlock x:Name="turnText" 
                   HorizontalAlignment="Left" 
                   Margin="302,10,0,0" 
                   TextWrapping="Wrap" 
                   Text="Turn = X" 
                   VerticalAlignment="Top"
                   Foreground="#FFFB0707" FontSize="20"/>
    </Grid>
    <Grid x:Name="theGrid">
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        <Image x:Name="cell9" Grid.Column="2" Grid.Row="2" Source="Images/Logo.png" Tapped="cell9_Tapped"/>
        <Image x:Name="cell8" Grid.Column="1" Grid.Row="2" Source="Images/Logo.png" Tapped="cell8_Tapped"/>
        <Image x:Name="cell7" Grid.Column="0" Grid.Row="2" Source="Images/Logo.png" Tapped="cell7_Tapped"/>
        <Image x:Name="cell4" Grid.Column="0" Grid.Row="1" Source="Images/Logo.png" Tapped="cell4_Tapped"/>
        <Image x:Name="cell1" Grid.Column="0" Grid.Row="0" Source="Images/Logo.png" Tapped="cell1_Tapped"/>
        <Image x:Name="cell5" Grid.Column="1" Grid.Row="1" Source="Images/Logo.png" Tapped="cell5_Tapped"/>
        <Image x:Name="cell2" Grid.Column="1" Grid.Row="0" Source="Images/Logo.png" Tapped="cell2_Tapped"/>
        <Image x:Name="cell6" Grid.Column="2" Grid.Row="1" Source="Images/Logo.png" Tapped="cell6_Tapped"/>
        <Image x:Name="cell3" Grid.Column="2" Grid.Row="0" Source="Images/Logo.png" Tapped="cell3_Tapped"/>
    </Grid>
</StackPanel>

现在查看后面的代码：

bool turn = true;
    int moveCount1 = 0;
    BitmapImage xImage = new BitmapImage(new Uri("ms-appx:///Images/X.png"));
    BitmapImage oImage = new BitmapImage(new Uri("ms-appx:///Images/O.png"));
    BitmapImage nullImage = new BitmapImage(new Uri("ms-appx:///Images/Logo.png"));
    public MainPage()
    {
        this.InitializeComponent();
        this.NavigationCacheMode = NavigationCacheMode.Required;
        theGrid.Visibility = Windows.UI.Xaml.Visibility.Collapsed;
        turnText.Visibility = Windows.UI.Xaml.Visibility.Collapsed;
        this.Winner();
    }

letsPlay按钮和Reset（）方法：

    private void letsPlay_Click(object sender, RoutedEventArgs e)
        {
            Reset();
        }
void Reset()
        {
            theGrid.Visibility = Windows.UI.Xaml.Visibility.Visible;
            turnText.Visibility = Windows.UI.Xaml.Visibility.Visible;
            turn = true;
            turnText.Text = "Turn = X";
            moveCount1 = 0;
            cell1.Source = nullImage;
            cell1.Tapped += cell1_Tapped;
            cell2.Source = nullImage;
            cell2.Tapped += cell2_Tapped;
            cell3.Source = nullImage;
            cell3.Tapped += cell3_Tapped;
            cell4.Source = nullImage;
            cell4.Tapped += cell4_Tapped;
            cell5.Source = nullImage;
            cell5.Tapped += cell5_Tapped;
            cell6.Source = nullImage;
            cell6.Tapped += cell6_Tapped;
            cell7.Source = nullImage;
            cell7.Tapped += cell7_Tapped;
            cell8.Source = nullImage;
            cell8.Tapped += cell8_Tapped;
            cell9.Source = nullImage;
            cell9.Tapped += cell9_Tapped;
        }

这是一个单元代码示例：

private void cell9_Tapped(object sender, TappedRoutedEventArgs e)
    {
        if (turn)
        {
            cell9.Source = xImage;
            turn = !turn;
            turnText.Text = "Turn = O";
        }
        else
        {
            cell9.Source = oImage;
            turn = !turn;
            turnText.Text = "Turn = X";
        }
        cell9.Tapped -= cell9_Tapped;
        moveCount1++;
    }

最后是Winner（）方法：

public void Winner()
    {
        if (
            (cell1.Source == xImage && cell2.Source == cell1.Source && cell3.Source == cell1.Source) ||
            (cell4.Source == xImage && cell5.Source == cell4.Source && cell6.Source == cell4.Source) ||
            (cell7.Source == xImage && cell8.Source == cell7.Source && cell9.Source == cell7.Source) ||
            (cell1.Source == xImage && cell5.Source == cell1.Source && cell9.Source == cell1.Source) ||
            (cell3.Source == xImage && cell5.Source == cell3.Source && cell7.Source == cell3.Source) ||
            (cell1.Source == xImage && cell4.Source == cell1.Source && cell7.Source == cell1.Source) ||
            (cell2.Source == xImage && cell5.Source == cell2.Source && cell8.Source == cell2.Source) ||
            (cell3.Source == xImage && cell6.Source == cell3.Source && cell9.Source == cell3.Source)
            )
        {
            ImageBrush xWins1 = new ImageBrush();
            xWins1.ImageSource = xImage;
            theGrid.Background = xWins1;
        }
        else if (
            (cell1.Source == oImage && cell2.Source == cell1.Source && cell3.Source == cell1.Source) ||
            (cell4.Source == oImage && cell5.Source == cell4.Source && cell6.Source == cell4.Source) ||
            (cell7.Source == oImage && cell8.Source == cell7.Source && cell9.Source == cell7.Source) ||
            (cell1.Source == oImage && cell5.Source == cell1.Source && cell9.Source == cell1.Source) ||
            (cell3.Source == oImage && cell5.Source == cell3.Source && cell7.Source == cell3.Source) ||
            (cell1.Source == oImage && cell4.Source == cell1.Source && cell7.Source == cell1.Source) ||
            (cell2.Source == oImage && cell5.Source == cell2.Source && cell8.Source == cell2.Source) ||
            (cell3.Source == oImage && cell6.Source == cell3.Source && cell9.Source == cell3.Source)
            )
        {
            ImageBrush oWins1 = new ImageBrush();
            oWins1.ImageSource = oImage;
            theGrid.Background = oWins1;
        }
        else if (moveCount1 == 9)
        {
            ImageBrush tie1 = new ImageBrush();
            tie1.ImageSource = nullImage;
            theGrid.Background = tie1;
        }
    }

谢谢您提供的任何帮助，如果您需要更多详细信息，请提前询问。

Answer 1

首先，如果您将单元作为数组访问并实现checkHorizon(int column) / checkVerticals(int row) / checkCross(bool isRightToLeft)函数，则该代码看起来会更好得多-该函数可以接收数字并检查为获胜者选择的水平/垂直/交叉线，并返回一个值。 由于我不确定在wpf中是否有一种简单的方法可以将gridView作为数组进行访问，因此，如果您手动插入9个单元格，则此链接提供了一种适用于C＃的方法。

您的第一个问题是有关按钮OnClick事件在第一次尝试时未触发。 发生此问题的原因有很多-当我过去为ASP.NET编程时，我会想到这类问题与page_load和ASP页面生命周期有关。 看看wpf的等价物，让我知道它是否解决了您的问题

您的第二个问题非常简单。 您希望Winner()函数更改图像（如果我正确获取此图像）。 我认为问题还是与对象生命周期有关-问题是对象已全部加载到页面，因此，要查看更改，必须在更改后刷新页面 。

然后是第三个问题，可能是前两个问题的解决方案。 如何刷新您询问的页面？ 我从另一个来源借来了语法，因为我从ASP修改了上下文。 解决方案是将用户重定向到您的页面，然后网格将首先重新加载自身。 您可以这样做：

const string pageName = "insert your page name here";
/*Insert some other code here*/
public static redirect(string directionName)
{
    Response.Redirect(directionName+".aspx");
}
/* Insert some more code here */

每当gridview发生变化时，您都可以简单地使用redirect(pageName);

祝您好运，如果您还有其他无法解决的问题，请告诉我:)
