C#.Net组件开发(高级篇) - 开发复杂的设计时组件编辑器
积累了开发组件的基本知识，现在分享一个复杂的设计时组件编辑器，如下图：
该组件编辑器用于设计CSFrameworkComponent.InnerObject对象的内容。
InnerObject对象定义了两个字符类型的属性(ObjectCreator,ObjectName)和一个MyNodeCollection集合类型。
在窗体上拖放一个CSFrameworkComponent组件，点右键选择“编辑MyInnerObject对象”菜单。
InnerObject对象定义：
/// <summary>
/// 对象类型
/// </summary>
public class InnerObject
{
public InnerObject()
{
_ObjectName = "对象名:" DateTime.Now.Ticks.ToString();
_ObjectCreator = "Jonny Sun - C/S框架网";
_MyNodeCollection = new MyNodeCollection();
}
private string _ObjectName = "";
public string ObjectName
{
get { return _ObjectName; }
set { _ObjectName = value; }
}
private string _ObjectCreator = "";
public string ObjectCreator
{
get { return _ObjectCreator; }
set { _ObjectCreator = value; }
}
private MyNodeCollection _MyNodeCollection;
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
[Editor(typeof(MyCollectionEditor), typeof(UITypeEditor))]//属性编辑器
public MyNodeCollection MyNodeCollection
{
get
{
return _MyNodeCollection;
}
set
{
_MyNodeCollection = value;
}
}
public override string ToString()
{
//在属性编辑器内显示的名称
return "(我的自定义对象)";
}
}

CSFrameworkComponent 组件：
/// <summary>
/// 用户自定义组件
/// </summary>
[ToolboxBitmap(typeof(CSFrameworkComponent), "CSFrameworkComponent.bmp")]
[DesignTimeVisible(true)]
[Designer(typeof(CSFrameworkComponentDesigner), typeof(IDesigner))]
public partial class CSFrameworkComponent : Component
{
//对象集合
private MyNodeCollection _MyNodeCollection;
//嵌套的对象
private InnerObject _MyInnerObject;
//窗体设计器的接口引用，当拖拉组件到窗体上，值由构造器传入．
private IContainer _Designer;
public CSFrameworkComponent(IContainer container)
: base()
{
if (container == null) throw new Exception("必须指定组件的容器！");
container.Add(this);
_Designer = container;//窗体的引用
//实例化自定义组件
_MyNodeCollection = new MyNodeCollection();
_MyInnerObject = new InnerObject();
}
/// <summary>
/// 移除窗体设计器内的代码
/// </summary>
/// <param name="disposing"></param>
protected override void Dispose(bool disposing)
{
//设计环境下销毁对象(移除Designer.cs内的代码)
if ((this.DesignMode) || (_Designer is IDesignerHost))
{
IDesignerHost host = (IDesignerHost)_Designer;
//从窗体设计器删除当前组件嵌套的组件代码
foreach (IComponent c in _MyNodeCollection)
host.Container.Remove(c); //销毁组件(删除Designer.cs内的代码)
//从窗体设计器删除当前组件嵌套的组件代码
foreach (IComponent c in _MyInnerObject.MyNodeCollection)
host.Container.Remove(c); //销毁组件(删除Designer.cs内的代码)
}
base.Dispose(disposing);
}
/// <summary>
