c# - .NET 中是否存在弱引用？

Question

我想在我的应用程序中保留某类对象的列表。但我仍然希望该对象被垃圾收集。您可以在 .NET 中创建弱引用吗？

供引用:

• Garbage Collecting objects which keep track of their own instances in an internal Map
• Create a weak reference to an object

来自 MSDN 的回答:

To establish a weak reference with an object, you create a WeakReference using the instance of the object to be tracked. You then set the Target property to that object and set the object to null. For a code example, see WeakReference in the class library.

是的，有一个通用的弱引用类。
