我有一个使用 .Net 远程处理构建的应用程序。验证时,如果有错误,我在服务器上抛出异常。异常是可序列化的。但是当服务器上抛出异常时,有时我会在客户端看到一个错误,上面写着“已建立的连接被主机中的软件中止”。

这是我在尝试调试服务器时从 windbg 获得的堆栈跟踪。看起来远程框架正在这样做。关于为什么关闭套接字以及如何处理这个问题的任何想法?

.Net 远程处理框架是否会在每次引发远程处理异常时关闭套接字?从使用 WinDbg 进行调试来看,情况如此。有人可以证实这一点吗?另外,根据特定情况,是否有时在发送响应后关闭套接字,有时在发送响应之前关闭套接字?

当我没有得到“已建立的连接被主机中的软件中止”时,这是来自客户端的 windbg 的跟踪。在这种情况下,我得到一个远程异常

在服务器上引发异常的是我们的自定义接收器,它负责安全性。我本可以将代码发布在一个地方并且直截了当。
