使用自定义集合编辑器以避免生成对象变量

看到这个问题，怎样让自定义控件的子控件不会自动生成变量定义？ 研究了一下Table对象，发现，你需要使用自定义的集合编辑器，示范编码如下

using System;<br /> using System.Collections;<br /> using System.Web.UI;<br /> using System.Web.UI.WebControls;<br /> using System.ComponentModel;<br /> using System.ComponentModel.Design;<br /> using System.Web.UI.Design.WebControls;<br /> using System.Drawing.Design;<br /> using System.Reflection;</p><div class='code-block code-block-3' style='margin: 8px 0; clear: both;'> <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <ins class="adsbygoogle" style="display:block; text-align:center;" data-ad-layout="in-article" data-ad-format="fluid" data-ad-client="ca-pub-6768214833031159" data-ad-slot="4803962711"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script></div> <p>namespace CSDNControls<br /> {<br /> [ToolboxData(“<{0}:ColorToolbar runat=server></{0}:ColorToolbar>”)]<br /> public class ColorToolbar : System.Web.UI.WebControls.WebControl<br /> {<br /> ColorButtonCollection colorButtons;</p> <pre><code> [PersistenceMode(PersistenceMode.InnerProperty)] public ColorButtonCollection Buttons { get { if (colorButtons == null) colorButtons = new ColorButtonCollection(this); return colorButtons; } } } [ToolboxItem(false)] public class ColorButton : Button { } [Editor(typeof(ColorButtonCollectionEditor),typeof(UITypeEditor))] public class ColorButtonCollection : CollectionBase { private Control _owner; internal ColorButtonCollection(Control owner) { this._owner = owner; } public ColorButton this[int Index] { get { return (ColorButton) List[Index]; } } public bool Contains(ColorButton btn) { return List.Contains(btn); } public int Add(ColorButton btn) { int i; i = List.Add(btn); _owner.Controls.Add(btn); return i; } public void Insert( int index, ColorButton btn ) { List.Insert( index, btn ); _owner.Controls.AddAt(index,btn); } public int IndexOf( ColorButton btn) { return List.IndexOf( btn ); } public void Remove(ColorButton btn) { List.Remove(btn); _owner.Controls.Remove(btn); } } public class ColorButtonCollectionEditor : CollectionEditor { public ColorButtonCollectionEditor(Type type) : base(type){} //protected override bool CanSelectMultipleInstances() {return false;} protected override object CreateInstance(Type itemType) { return Activator.CreateInstance(itemType, BindingFlags.CreateInstance | (BindingFlags.Public | BindingFlags.Instance), null, null, null); } } </code></pre> <p>}<br />
