c#自定义了一个控件集合属性后选择集合里的子属性的时候不显示属性说明

Question

如上图，在上图红框圈出来的一块，在集合属性里怎么就没有呢？
Description属性我也设置了private string _caption;
        [Browsable(true), Category("设置"), Description("列显示名")]
        public string Caption
        {
            get { return _caption; }
            set
            {
                _caption = value;
            }
        }

Answer 1

奇怪，我发现基础类库的Treeview有，但是ListView没有。

Answer 2

TreeviewNodeCollection定义
[Editor("System.Windows.Forms.Design.TreeNodeCollectionEditor, System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(UITypeEditor))]
public class TreeNodeCollection : IList, ICollection, IEnumerable
不知道有没有关系。
