窗口服务 - 配置文件 [英] windows service - config file

问题描述

我知道这可能已经问过，但我似乎无法找到正确的答案对我来说。

I know this has probably been asked before but I can't seem to find the right answer for me.

我有一个名为Windows服务的的 foobar.exe 的。我有一个名为应用程序配置文件的的 foobar.exe.config 的在同一文件夹。

I have a windows service named foobar.exe. I have an application configuration file named foobar.exe.config in the same folder.

是配置文件只在启动时读取？

我想更改配置文件，而无需重新启动该服务，但是这是我能得到新的设置读取的唯一方法。

I would like to make changes to the config file without having to restart the service but that is the only way I can get the new settings read.

我究竟做错了什么？

可以在Windows的服务有一个动态的配置文件？

推荐答案

.NET应用程序将读取其配置文件在启动并缓存性能的原因。

.NET applications will read their config files at startup and cache them for performance reasons.

我看到周围这两种基本方式：

I see two basic ways around this:

• 在你的服务，跟踪的上次更新日期/时间配置文件。定期检查最后更新日期，如果你发现一个变化，重新加载配置文件

• in your service, keep track of the last update date/time for the config file. Check this last update date regularly and if you detect a change, re-load the config file

Windows NT服务可以以一种特殊的<一个回应href="http://msdn.microsoft.com/en-US/library/system.serviceprocess.servicebase.oncustomcommand%28v=VS.80%29.aspx"><$c$c>OnCustomCommand事件。你可以实现这样的事件处理程序重新加载配置，当你做更改配置，你可以有一个小工具的信号为您服务的配置已发生变化，发送自定义命令为您服务

a Windows NT service can respond to a special OnCustomCommand event. You could implement such an event handler to reload the config, and when you do change the config, you could have a small utility to signal to your service that the config has changed and send that "custom command" to your service
