如何将验证绑定到RadioButton WPF

public class MyViewModel : INotifyPropertyChanged
{
    private bool _isChecked;

    public bool IsChecked
    {
        get { return _isChecked; }
        set
        {
            if (_isChecked != value)
            {
                _isChecked = value;
                OnPropertyChanged(nameof(IsChecked));
            }
        }
    }

    // 实现INotifyPropertyChanged接口的代码...
}

<Window x:Class="MyApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:MyApp"
        Title="My App" Height="450" Width="800">
    <Window.DataContext>
        <local:MyViewModel />
    </Window.DataContext>
    
    <Grid>
        <RadioButton Content="Option 1" IsChecked="{Binding IsChecked}" />
        <RadioButton Content="Option 2" IsChecked="{Binding IsChecked}" />
        <RadioButton Content="Option 3" IsChecked="{Binding IsChecked}" />
    </Grid>
</Window>

public class MyViewModel : INotifyPropertyChanged
{
    public ICommand RadioButtonCommand { get; }

    public MyViewModel()
    {
        RadioButtonCommand = new RelayCommand(ExecuteRadioButtonCommand);
    }

    private void ExecuteRadioButtonCommand(object parameter)
    {
        // 处理RadioButton的选中事件
    }

    // 其他代码...
}

<Grid>
    <RadioButton Content="Option 1" Command="{Binding RadioButtonCommand}" />
    <RadioButton Content="Option 2" Command="{Binding RadioButtonCommand}" />
    <RadioButton Content="Option 3" Command="{Binding RadioButtonCommand}" />
</Grid>
