WPF数据绑定 - "自定义类型描述符"的示例

public class CustomTypeDescriptor : PropertyDescriptor
{
    public CustomTypeDescriptor(string name, Type componentType)
        : base(name, null)
    {
        ComponentType = componentType;
    }

    public override Type ComponentType { get; }

    public override bool IsReadOnly => false;

    public override Type PropertyType => typeof(string);

    public override object GetValue(object component)
    {
        // 获取数据的逻辑
    }

    public override void SetValue(object component, object value)
    {
        // 设置数据的逻辑
    }

    public override bool CanResetValue(object component)
    {
        return false;
    }

    public override void ResetValue(object component)
    {
    }

    public override bool ShouldSerializeValue(object component)
    {
        return false;
    }
}
