c# - 隐藏 WPF 窗口中的所有按钮

Question

我是 WPF 新手。我有一个带有多个按钮的窗口。我想隐藏窗口中的所有按钮，除了一个。按钮动态添加到窗口。

XAML 代码:

<Grid>
<Button x:Name="btnA"/>
<Button x:Name="btnB" />
<Button x:Name="btnC"/>
<Button x:Name="btnD" />
<Button x:Name="btnE"/>
<Button x:Name="btnF" />
<Button x:Name="btnG"/>
<Button x:Name="btnH" />
    <StackPanel >
         <Button x:Name="btnHideAllButtons" click="btnHideAllButtons_Click"/>
    </StackPanel>
</Grid>

C#代码

 private void btnHideAllButtons_Click(object sender, RoutedEventArgs e)
        {
           //Code to Hide all Buttons

            btnHideAllButtons.Visibility = Visibility.Visible;
        }

Answer 1

将所有按钮放在一个列表中:

public List<Button> allButtons; //(declared on your Window's cs)

//Initialize on your constructor
allButtons = new List<Button>() {btnA,btnB,/*and so on*/}

然后做一个foreach

private void btnHideAllButtons_Click(object sender, RoutedEventArgs e)
{
   foreach (Button button in allButtons)
   {
        button.Visibility = Visibility.Collapsed;
   }
   btnHideAllButtons.Visibility = Visibility.Visible;
}
