AppDomain 和 MarshalByRefObject 生命周期:如何避免 RemotingException? [英] AppDomain and MarshalByRefObject life time : how to avoid RemotingException?

问题描述

当 MarshalByRef 对象从 AppDomain (1) 传递到另一个 (2) 时，如果在第二个 AppDomain (2) 中调用方法之前等待 6 分钟，您将收到 RemotingException :

When a MarshalByRef object is passed from an AppDomain (1) to another (2), if you wait 6 mins before calling a method on it in the second AppDomain (2) you will get a RemotingException :

System.Runtime.Remoting.RemotingException:对象 [...] 已断开连接或服务器上不存在.

System.Runtime.Remoting.RemotingException: Object [...] has been disconnected or does not exist at the server.

关于这个问题的一些文档:

如果我错了，请纠正我:如果 InitializeLifetimeService 返回空值，则只能在 AppDomain 2 卸载时在 AppDomain 1 中收集对象，即使收集了代理?

Correct me if I'm wrong : if InitializeLifetimeService returns null, the object can only be collected in AppDomain 1 when AppDomain 2 is Unloaded, even if the proxy was collected ?

有没有办法禁用生命周期并使代理(在 AppDomain 2 中)和对象(在 AppDomain1 中)保持活动状态，直到代理完成?也许与ISponsor...?

Is there a way to disable life time and keep the proxy (in AppDomain 2) and the object (in AppDomain1) alive until the proxy is Finalized ? Maybe with ISponsor... ?

基本上说:

[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.Infrastructure)]
public override object InitializeLifetimeService()
{
  return null;
}
