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.
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，控件会随着集合的变化而自动更新，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，您的控件应该随着集合的变化而更新.
The easiest solution is to use BindingList<T> instead of ObservableCollection<T>. After that, your controls should update as the collection changes.
