Notes to Inheritors:
This editor can edit collections that have an Item property. The editor can determine the type of the collection from the Item property, if it exists. If the collection does not have this property, or if you want to provide collections of more than one type, you can override certain protected members of this class to customize the editor to support other types of collections.
The following code example uses an EditorAttribute to associate the CollectionEditor with a property.
public: [EditorAttribute(System::ComponentModel::Design::CollectionEditor::typeid, System::Drawing::Design::UITypeEditor::typeid)] property ICollection^ testCollection { ICollection^ get() { return Icollection; } void set( ICollection^ value ) { Icollection = value; } } private: ICollection^ Icollection;

Any public static ( Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
