问题描述

在 Azure 网站中，我总是使用以下代码从配置的应用设置中获取一些值:

In an Azure Websites I was always using the following code to fetch some values from the config's app settings:

string property = WebConfigurationManager.AppSettings["property"];  

就在几天前，我偶然发现了 CloudConfigurationManager，有了它我可以得到这样的属性:

Just a couple of days ago I stublemd upon CloudConfigurationManager, and with it I can get the property like so:

string property = CloudConfigurationManager.GetSetting("property"); 

虽然 CloudConfigurationManager 似乎更适合云使用，但我从未遇到过 WebConfigurationManager 的任何问题.

Although CloudConfigurationManager seems like it's better fitted to cloud use, I never had any issues with WebConfigurationManager.

• 我应该使用 CloudConfigurationManager 吗?
• 两者有什么区别?
• 在什么情况下 CloudConfigurationManager 的行为会不同于
  WebConfigurationManager?

推荐答案

CloudConfigurationManager 让我们无论身处何种环境都可以读取配置文件.

CloudConfigurationManager enables us to read configuration file regardless of the environment we are in.

因此，不要编写特定于环境的代码语句，例如用于 web.config 文件:

So instead of writing environment specific code statements e.g., for web.config file:

WebConfigurationManager.AppSettings["MySetting"]

WebConfigurationManager.AppSettings["MySetting"]

对于 ServiceConfiguration.cscfg 文件:

For ServiceConfiguration.cscfg file:

RoleEnvironment.GetConfigurationSettingValue("MySetting")

RoleEnvironment.GetConfigurationSettingValue("MySetting")

我们可以编写下面的语句，它将从所有配置文件(即 app.config、web.config 和 ServiceConfiguration.cscfg)中读取值.

We can write the below statement, which will read values from all the configuration files i.e., app.config, web.config and ServiceConfiguration.cscfg.

CloudConfigurationManager.GetSetting("MySetting")

CloudConfigurationManager.GetSetting("MySetting")
