WPF:根据条件在ComBoBox中填充不同的枚举

public enum MyEnum
{
    Option1,
    Option2,
    Option3
}

<ComboBox ItemsSource="{Binding MyEnumValues}" SelectedItem="{Binding SelectedMyEnum}" />

public class MyViewModel : INotifyPropertyChanged
{
    public ObservableCollection<MyEnum> MyEnumValues { get; set; }
    private MyEnum selectedMyEnum;

    public MyEnum SelectedMyEnum
    {
        get { return selectedMyEnum; }
        set
        {
            selectedMyEnum = value;
            OnPropertyChanged(nameof(SelectedMyEnum));
        }
    }

    public MyViewModel()
    {
        MyEnumValues = new ObservableCollection<MyEnum>();
        // 根据条件添加不同的枚举值
        if (condition1)
        {
            MyEnumValues.Add(MyEnum.Option1);
        }
        if (condition2)
        {
            MyEnumValues.Add(MyEnum.Option2);
        }
        if (condition3)
        {
            MyEnumValues.Add(MyEnum.Option3);
        }
    }

    // 实现INotifyPropertyChanged接口
    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}
