我不明白 DefaultProperty 元数据标签如何工作或其含义。我已阅读 MSDN 并浏览了示例，但发现它令人困惑。

我'我读过一些博客，它们似乎提到了索引器。我不确定您为什么需要属性的元数据？我有 Java 背景，或许 Java 类比会有所帮助。

[DefaultProperty("Value")]
    public abstract class FOO<T> : ANY, IBAR<T>
    {
        public FOO() { }
        public FOO(T value) { this.Value = value; }
        public virtual T Value { get; set; }
    }

I do not understand how the DefaultProperty Metadata tag work or what it signifies.
I've read the MSDN and went through the sample but I find it confusing.

DefaultPropertyAttribute Class

I've read a few blogs and they seem to refer to the indexers. I'm not sure why you would want metadata for your properties? I am coming from a Java background, perhaps a Java analogy would help.

[DefaultProperty("Value")]
    public abstract class FOO<T> : ANY, IBAR<T>
    {
        public FOO() { }
        public FOO(T value) { this.Value = value; }
        public virtual T Value { get; set; }
    }
