RadioButton

同属一个GroupName则互斥，只能选择一个

<StackPanel Orientation="Vertical">
    <Label Content="Group1:水果"></Label>
    <RadioButton GroupName="Group1" Content="苹果"></RadioButton>
    <RadioButton GroupName="Group1" Content="荔枝"></RadioButton>
    <RadioButton GroupName="Group1" Content="西瓜"></RadioButton>
    <RadioButton GroupName="Group1" Content="香蕉"></RadioButton>
    <Label Content="Group2:科目"></Label>
    <RadioButton GroupName="Group2" Content="语文"></RadioButton>
    <RadioButton GroupName="Group2" Content="数学"></RadioButton>
    <RadioButton GroupName="Group2" Content="英语"></RadioButton>
    <RadioButton GroupName="Group2" Content="物理"></RadioButton>
</StackPanel>

上面的示例中，可以选择水果、科目下各一个选项，所以水果和科目不互斥，水果之间互斥，科目之间互斥
