Question

我正在尝试在我的xaml.cs代码中创建一个if语句，这将允许我根据按下的按钮启用复选框中的某些值例如：按钮1启用值1,2,3和4，按钮2启用值5,6,7和8

这是我到目前为止所拥有的

private void EnableAll(object sender, RoutedEventArgs e)
        {
            if(1 == true)
            {
                chk_1.IsChecked = true;
                chk_2.IsChecked = true;
                chk_3.IsChecked = true;
                chk_4.IsChecked = true;
            }

            if(1 == false)
            {
                chk_1.IsChecked = false;
                chk_2.IsChecked = false;
                chk_3.IsChecked = false;
                chk_4.IsChecked = false;
            }

            if(2 == true)
            {
                chk_5.IsChecked = true;
                chk_6.IsChecked = true;
                chk_7.IsChecked = true;
                chk_8.IsChecked = true;
            }

            if(2 == false)
            {
                chk_5.IsChecked = false;
                chk_6.IsChecked = false;
                chk_7.IsChecked = false;
                chk_8.IsChecked = false;
            }
        }

这与下面的XAML事件相关联

        <Button Name="btnEnable_1" Content="Enable" Click="#make 1 true#"/>
        <Button Name="btnDisable_1" Content="Disable" Click="#make 1 false#"/>

Click =“”中的位需要将值1分别设为true和false

我知道我想要什么，但我不知道如何联系它们，我相信有更简单的方法可以做到......如果有人可以提供帮助，那就太棒了！

为每个按钮添加一个事件处理程序

    <Button Name="btnEnable_1" Content="Enable" Click="myButton_Click" />
    <Button Name="btnDisable_1" Content="Disable" Click="myButton_Click" />

在代码背后：

    private void myButton_Click(object sender, RoutedEventArgs e)
    {
        var button = (Button)sender;
        var enabled = button.Name == "btnEnable_1";

        chk_1.IsChecked = enabled;
        chk_2.IsChecked = enabled;
        chk_3.IsChecked = enabled;
        chk_4.IsChecked = enabled;
        chk_5.IsChecked = !enabled;
        chk_6.IsChecked = !enabled;
        chk_7.IsChecked = !enabled;
        chk_8.IsChecked = !enabled;
    }

if语句根据按钮单击C＃和XAML启用某些值
