添加到标签内容，而不是覆盖WPF C＃

Question

我制作了一个小的WPF程序。但这是我的第一个，我已经画了一个空白。我已经弄清楚了如何对数据进行绑定并将内容从复选框添加到标签。

[我的问题是，当我按“小咖啡”，然后再按“加糖”时，我希望它添加到字符串中，而不是覆盖那里的内容。我想我需要使用Append。但这是我的第一次，我也不知道如何用代码将其记录下来。谢谢。

XAML

<RadioButton Content="Small" HorizontalAlignment="center" VerticalAlignment="Top" Margin="300,55,0,0" Click="SmlClicked"></RadioButton>
<RadioButton Content="Medium" HorizontalAlignment="center" VerticalAlignment="Top" Margin="450,55,0,0" Click="MdClicked"></RadioButton>

<CheckBox Name="SugarCheck" Content="Sugar" HorizontalAlignment="center" VerticalAlignment="Center" Margin="250,0,0,0" Checked="SugarChecked"></CheckBox>
<CheckBox Name="CreamCheck" Content="Cream" HorizontalAlignment="center" VerticalAlignment="Center" Margin="500,0,0,0" Checked="CreamChecked"></CheckBox>

<Label Name="order" Content="Your Coffee" HorizontalAlignment="center" VerticalAlignment="Center" Margin="170,145,0,0"></Label>

C＃

    private void SugarChecked(object sender, RoutedEventArgs e)
    {
        order.Text+= "with sugar";
    }
    private void CreamChecked(object sender, RoutedEventArgs e)
    {
        order.Content = "with cream";
    }



    private void SmlClicked(object sender, RoutedEventArgs e)
    {
        order.Content = "Small";
    }

    private void MdClicked(object sender, RoutedEventArgs e)
    {
        order.Content = "Medium";
    }

    private void LrgClicked(object sender, RoutedEventArgs e)
    {
        order.Content = "Large";
    }

Answer 1

private void SugarChecked(object sender, RoutedEventArgs e)
{
    order.Content += "with sugar";
}
private void CreamChecked(object sender, RoutedEventArgs e)
{
    order.Content += "with cream";
}

private void SmlClicked(object sender, RoutedEventArgs e)
{
    order.Content += "Small";
}

private void MdClicked(object sender, RoutedEventArgs e)
{
    order.Content += "Medium";
}

private void LrgClicked(object sender, RoutedEventArgs e)
{
    order.Content += "Large";
}

尽管您的字符串格式会很糟糕...

最好是利用这次机会来学习Converters，让Coffee类根据您对按钮的操作而变化，并使用自定义转换器将其绑定到标签上：）
