winform propertygrid 可以出现radiobutton

是的，WinForm的PropertyGrid可以通过使用自定义属性描述符和UI类型编辑器来显示RadioButton。

要实现这个功能，你需要首先创建一个自定义属性描述符类，该类继承自System.ComponentModel.PropertyDescriptor。在这个类中，你需要重写GetValue和SetValue方法，以便从类的属性中获取和设置值。接下来，你需要创建一个自定义的UI类型编辑器类，该类继承自System.Drawing.Design.UITypeEditor，并重写EditValue方法，以便在PropertyGrid中显示RadioButton。

下面是一个示例：

public class RadioButtonPropertyDescriptor : PropertyDescriptor
{
    private readonly RadioButtonGroup _group;
    private readonly RadioButton _button;

    public RadioButtonPropertyDescriptor(string name, Attribute[] attrs, RadioButtonGroup group)
        : base(name, attrs)
    {
        _group = group;
        _button = new RadioButton() { Text = name, Checked = false };
        _button.CheckedChanged += (sender, args) =>
        {
            if (_button.Checked)
            {
                _group.Value = _button.Text;
            }
        };
    }

    public override Type ComponentType => typeof(RadioButtonGroup);
    public override bool IsReadOnly => false;
    public override Type PropertyType => typeof(string);
    public override bool CanResetValue(object component) => false;
    public override object GetValue(object component) => _button.Checked ? _button.Text : null;
    public override void ResetValue(object component) { }
    public override void SetValue(object component, object value) => _button.Checked = (string)value == _button.Text;
    public override bool ShouldSerializeValue(object component) => false;

    public override void AddValueChanged(object component, EventHandler handler) => _button.CheckedChanged += handler;
    public override void RemoveValueChanged(object component, EventHandler handler) => _button.CheckedChanged -= handler;

    public override object GetEditor(Type editorBaseType) => new RadioButtonEditor();
    public override bool IsBrowsable => true;
}

public class RadioButtonGroup
{
    private string _value;
    private PropertyDescriptorCollection _properties;

    public RadioButtonGroup(PropertyDescriptorCollection properties)
    {
        _properties = properties;
    }

    public string Value
    {
        get => _value;
        set
        {
            if (_value != value)
            {
                _value = value;
                _properties.Find(_value, true)[0].SetValue(this, true);
            }
        }
    }
}

public class RadioButtonEditor : UITypeEditor
{
    private IWindowsFormsEditorService _editorService;

    public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
    {
        _editorService = provider.GetService(typeof(IWindowsFormsEditorService)) as IWindowsFormsEditorService;
        if (_editorService == null) return value;

        var group = (context.Instance as RadioButtonGroup);
        var buttons = group != null ? group.Value : null;
        var property = context.PropertyDescriptor as RadioButtonPropertyDescriptor;
        var radioButton = property != null ? property.RadioButton : null;

        var panel = new FlowLayoutPanel() { AutoSize = true };
        foreach (PropertyDescriptor prop in context.PropertyDescriptorCollection)
        {
            var radioButtonProp = prop as RadioButtonPropertyDescriptor;
            if (radioButtonProp != null)
            {
                panel.Controls.Add(radioButtonProp.RadioButton);
                if (radioButtonProp.RadioButton.Checked)
                {
                    buttons = radioButtonProp.RadioButton.Text;
                }
            }
        }

        if (_editorService.ShowDialog(panel) == DialogResult.OK)
        {
            return buttons;
        }

        return value;
    }

    public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context) => UITypeEditorEditStyle.DropDown;
}

在这个示例中，我们创建了一个名为RadioButtonPropertyDescriptor的自定义属性描述符类，它包含了一个RadioButton作为属性的UI类型编辑器。我们还创建了一个名为RadioButtonGroup的类，它包含了一个字符串值和一个属性描述符集合。最后，我们还创建了一个名为RadioButtonEditor的UI类型编辑器，用于在PropertyGrid中显示RadioButton。

使用这些类，你可以像这样在PropertyGrid中显示RadioButton：

var properties = new PropertyDescriptorCollection(new PropertyDescriptor[]
{
    new RadioButtonPropertyDescriptor("Option1", new Attribute[] { }, group),
    new RadioButtonPropertyDescriptor("Option2", new Attribute[] { }, group),
    new RadioButtonPropertyDescriptor("Option3", new Attribute[] { }, group),
});

var group = new RadioButtonGroup(properties);
var propertyGrid = new PropertyGrid() { SelectedObject = group };

在这个示例中，我们创建了一个包含三个RadioButton的RadioButtonGroup，并将其传递给了一个PropertyGrid。当用户选择一个RadioButton时，它的值将自动保存到RadioButtonGroup的Value属性中。
