关闭和处理 WCF 服务 [英] Closing and Disposing a WCF Service

问题描述

ICommunicationObject 上的 Close 方法可以抛出两种类型的异常，如 MSDN 概述此处.我理解为什么 Close 方法会抛出这些异常，但我不明白的是为什么服务代理上的 Dispose 方法调用 Close 周围没有 try 的方法.您的 Dispose 方法不是您想要确保不抛出任何异常的地方吗?

The Close method on an ICommunicationObject can throw two types of exceptions as MSDN outlines here. I understand why the Close method can throw those exceptions, but what I don't understand is why the Dispose method on a service proxy calls the Close method without a try around it. Isn't your Dispose method the one place where you want make sure you don't throw any exceptions?
