我有3个问题： 1-第一次按下“letsPlay”按钮可以在任何地方按下oImage，但之后工作正常。 2-Winner（）方法不起作用......它什么都不做。 3 - 如何重置我的网格背景，因为我找不到任何关于它的结果。
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>
现在为后面的代码运行：
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++;
}
最后这是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;
}
}
我将感谢你们给予的任何帮助，如果你需要更多细节，请提前询问。
答案 0 :(得分：0)
首先，如果您将单元格作为数组访问并实现checkHorizon(int column) / checkVerticals(int row) / checkCross(bool isRightToLeft)函数，那么代码看起来会更好一些，即收到数字的函数，并检查获胜者的选定水平/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作为一个数组进行访问，如果你手动插入9个单元格，这里有一个link的方法可以使用C＃。
你的第一个问题是关于button OnClick event not firing on the first try.这个问题可能发生的原因很多 - 我曾经为ASP.NET编程时遇到这种问题与page_load和ASP页面生命周期有关。看看the equivallent for wpf,并告诉我它是否解决了您的问题
你的第二个问题非常相似。如果我能正确理解，您希望Winner()功能更改图像。我认为问题再次与对象生命周期有关 - 问题是对象已经全部加载到页面，因此为了查看更改，您必须在更改后刷新页面。 / p>
然后是第三个问题，这可能是前两个问题的解决方案。如何刷新你问的页面？我从Another source借用了语法，因为我重新从ASP中获取了上下文。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己。你可以这样做：
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，您只需使用redirect(pageName);
祝你好运，如果您还有其他问题无法解决，请告诉我们。）
