推荐答案

根据您的问题，听起来您正在尝试在WinForms应用程序中使用ObservableCollection<T>.

Based on your question, it sounds like you're trying to use ObservableCollection<T> in a WinForms application.

ObservableCollection<T>主要用于WPF开发.在WinForms中，控件会在集合更改时自动更新，您的集合需要实现IBindingList.

ObservableCollection<T> is primarily used in WPF development. In WinForms, for the control be automatically updates as the collection changes your collection needs to implement IBindingList.

最简单的解决方案是使用BindingList<T>而不是ObservableCollection<T>.之后，您的控件应随集合的更改而更新.

The easiest solution is to use BindingList<T> instead of ObservableCollection<T>. After that, your controls should update as the collection changes.
