c# - WCF 服务调用中的 "Thread was being aborted"

Question

在我的程序中有一个包含 wcf 客户端的 aspx 页面，因此调用位于同一服务器上的 wcf 服务。

当我的 wcf 客户端调用生产服务器上 IIS 中托管的 wcf 服务时，我会遇到此异常。

例。 msg: 线程正在中止。

Ex 堆栈:

我使用 PRTG Ipmonitor，它给了我太多关于“请求当前”传感器的请求。我的网站在浏览器中可用。如果删除这个调用服务的页面，一切都会好的。

听起来您没有关闭 WCF 客户端。

我认为正在发生的事情是:

• 用户调用aspx页面
• aspx页面调用服务
• aspx页面返回给用户
• 服务客户端未关闭，因此请求处于打开状态且当前请求数很高
• 最终您打开了最大数量的请求
• 页面等待空闲连接，当它没有获得一个 aspx 页面超时
• 然后你从超时中得到一个线程中止异常
