備註

BindingList<T>類別可用來當做基底類別建立雙向資料繫結機制。The BindingList<T> class can be used as a base class to create a two-way data-binding mechanism. BindingList<T> 提供的具象的一般實作IBindingList介面。BindingList<T> provides a concrete, generic implementation of the IBindingList interface. 這是實作完整的替代IBindingList介面,由於微妙的互動之間很難IBindingListIEditableObject,和相關聯CurrencyManagerThis is an alternative to implementing the complete IBindingList interface, which can be difficult because of the subtle interaction between IBindingList, IEditableObject, and the associated CurrencyManager. 不過,典型方案程式設計人員會使用這個類別提供資料繫結功能,例如BindingSource,而不是直接使用BindingList<T>However, the typical solutions programmer will use a class that provides data binding functionality, such as BindingSource, instead of directly using BindingList<T>.

BindingList<T> 支援透過可延伸原廠建立的執行個體AddNew方法。BindingList<T> supports factory-created instances through the extensible AddNew method. (相同類型的擴充性中也有其他類別,例如BindingSource) 此外,因為這個類別會實作ICancelAddNew介面,它可讓交易的認可或回復新的項目,透過EndNewCancelNew方法。(This same type of extensibility is also found in other classes, such as BindingSource) In addition, since this class implements the ICancelAddNew interface, it enables transactional commits or rollbacks of the new item through the EndNew and CancelNew methods.
