＆QUOT;对象已断开或服务器＆QUOT不存在;例外 [英] "Object has been disconnected or does not exist at the server" exception
问题描述
我要在我的应用程序使用跨AppDomain的电话，有时我有这个RemotingException：
对象/2fa53226_da41_42ba_b185_ec7d9c454712/ygiw+xfegmkhdinj7g2kpkhc_7.rem已断开或在服务器不存在。
目标对象还活着，我已经检查了。
I need to use cross-appdomain calls in my app, and sometimes I have this RemotingException:
Object '/2fa53226_da41_42ba_b185_ec7d9c454712/ygiw+xfegmkhdinj7g2kpkhc_7.rem' has been disconnected or does not exist at the server.
The target object is still alive, I have checked it.
UPD我给自己定了目标对象的终结断点，它从来没有击中。因此，这个对象是活的，并没有GC'ed。
UPD I've set breakpoint in the finalizer of the target object, and it never hits. Thus, this object is alive and wasn't GC'ed.
推荐答案
这可能是因为当地的垃圾收集器在服务器端收集的对象。您可以prevent通过续订租赁。你可以阅读更多有关这些文章：
That is probably because the local garbage collector at the server side collects the object. You can prevent that by renewing the leasing. You can read more about that in these articles:
