Question

我正在编写点击红色背景按钮的功能。此功能无效。我有40个具有相同功能的按钮，用于点击＆＃34; ButClick＆＃34;。但当我点击任何按钮（例如绿色背景）时 - 计数器计数。我只想在点击红色背景的按钮时才这样做。

private void But_Click(object sender, RoutedEventArgs e)
{
    var column = Grid.GetColumn(sender as Button);
    var row = Grid.GetRow(sender as Button);
    LabelX.Content = column.ToString();
    LabelY.Content = row.ToString();

    if ((sender as Button).Background == new SolidColorBrush(Colors.Red));
    {
        counts += 1;
        LabelCounterOfClick.Content = counts.ToString();
    }

}

更新

现在它没有计算任何东西。当我点击任何按钮 - 计数器显示0.如果错误（它没有检测到红色），我的功能是什么东西

private void But_Click(object sender, RoutedEventArgs e) 
{ 
    var column = Grid.GetColumn(sender as Button); 
    var row = Grid.GetRow(sender as Button); 
    LabelX.Content = column.ToString(); 
    LabelY.Content = row.ToString();

    if ((sender as Button).Background == new SolidColorBrush(Colors.Red))
    {
        counts += 1;

    }
    else
    {
        counts = 0;
    }

    LabelCounterOfClick.Content = counts.ToString(); 
}

Answer 1

尝试在条件

之后删除行末尾的;

您可以使用“ Brushes.Red ”检查背景，而不是创建新对象

Answer 2

为什么要将ButClick事件附加到所有40个按钮？为什么不把它添加到那些红色？选择按钮上的属性，并将click事件分配给应该拥有它的人。

Answer 3

记住纠正AbduGo。

不是最好的解决方案，但尝试这样做，

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        Button btn = (Button)sender;

        Brush btnBrush = btn.Background;
        string color = "";
        if (btnBrush is SolidColorBrush)
        {
            color = ((SolidColorBrush)btnBrush).Color.ToString();
        }

        if (color ==  Brushes.Red.ToString())
        {
           //your logic of incrementing counter
        }
        else
        {
           //your logic of resting counter
        }
    }
