实现

注解

SynchronizedCollection<T> 将数据存储在 List<T> 容器中并提供一个对象,可以设置并使用该对象来同步对集合的访问,以使其成为线程安全集合。The SynchronizedCollection<T> stores data in a List<T> container and provides an object that can be set and used to synchronize access to the collection so that it is thread-safe. 可以使用 IList<T> 方法来恢复 Items 容器。The IList<T> container can be recovered using the Items method. 使用 SyncRoot 属性可以恢复同步对象。The synchronized object can be recovered using the SyncRoot property. 只能通过采用 syncRoot 参数的构造函数之一对其进行设置。It can only be set using one of the constructors that take the syncRoot parameter.
