推荐答案

从线程安全集合开始

线程安全收藏

至于知道什么线程添加了特定项目我不认为一个项目跟踪。我想你可以添加一个属性TheadName，并让线程输入该值。

As for knowing what thread added specific item I don't think an item tracks the tread. I think you could add a Property TheadName and have the thread enter that value.

问题陈述特定项目已添加。然后在注释中，OP推断出任何项目。

The question states "specific item had been added". Then in comment the OP infers any item.

.NET没有线程安全的ObservableCollection。有一些关于codeplex或可能重新思考你设计。 ConcurrentQueue可能是一个选项。

.NET does not have thread safe ObservableCollection. There are some on codeplex or possible rethink you design. ConcurrentQueue may be an option.
