如何在属性网格中显示动态对象？

using System;
using System.ComponentModel;
using System.Reflection;

// 定义一个动态对象
public class DynamicObject
{
    [DisplayName("名称")]
    public string Name { get; set; }

    [DisplayName("年龄")]
    public int Age { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        // 创建动态对象
        var dynamicObj = new DynamicObject();

        // 获取动态对象的属性信息
        var properties = dynamicObj.GetType().GetProperties();

        // 创建属性描述符列表
        var propertyDescriptors = new PropertyDescriptorCollection(null);

        // 遍历属性信息，将其转换为属性描述符，并添加到属性描述符列表中
        foreach (var property in properties)
        {
            var displayNameAttribute = property.GetCustomAttribute<DisplayNameAttribute>();
            var displayName = displayNameAttribute != null ? displayNameAttribute.DisplayName : property.Name;

            var propertyDescriptor = new DynamicPropertyDescriptor(property.Name, property.PropertyType, displayName);
            propertyDescriptors.Add(propertyDescriptor);
        }

        // 创建属性网格
        var propertyGrid = new PropertyGrid();

        // 绑定动态对象和属性描述符列表到属性网格
        propertyGrid.SelectedObject = dynamicObj;
        propertyGrid.PropertySort = PropertySort.Categorized;
        propertyGrid.BrowsableAttributes = propertyDescriptors;

        // 显示属性网格
        propertyGrid.ShowDialog();
    }
}

// 自定义属性描述符，用于在属性网格中显示属性
public class DynamicPropertyDescriptor : PropertyDescriptor
{
    private readonly Type propertyType;
    private readonly string displayName;

    public DynamicPropertyDescriptor(string name, Type propertyType, string displayName)
        : base(name, null)
    {
        this.propertyType = propertyType;
        this.displayName = displayName;
    }

    public override Type ComponentType => typeof(DynamicObject);

    public override bool IsReadOnly => false;

    public override Type PropertyType => propertyType;

    public override bool CanResetValue(object component) => false;

    public override object GetValue(object component) => component.GetType().GetProperty(Name).GetValue(component);

    public override void ResetValue(object component) { }

    public override void SetValue(object component, object value) => component.GetType().GetProperty(Name).SetValue(component, value);

    public override bool ShouldSerializeValue(object component) => false;

    public override string DisplayName => displayName;
}
