BaseCollection BaseCollection BaseCollection BaseCollection Class


提供用于在 System.Windows.Forms 命名空间中创建与数据相关的集合的基本功能。Provides the base functionality for creating data-related collections in the System.Windows.Forms namespace.

public ref class BaseCollection : MarshalByRefObject, System::Collections::ICollection
public class BaseCollection : MarshalByRefObject, System.Collections.ICollection
type BaseCollection = class
    inherit MarshalByRefObject
    interface ICollection
    interface IEnumerable
Public Class BaseCollection
Inherits MarshalByRefObject
Implements ICollection


BaseCollection类不应由应用程序开发人员使用。The BaseCollection class is not intended for use by application developers. 应用程序开发人员CollectionBase应该改用。Application developers should use CollectionBase instead.

BaseCollection 类实现 ICollection 接口。The BaseCollection class implements the ICollection interface.
