Azure的类库访问GetConfigurationSettingValue与web.config中 [英] Azure class library access GetConfigurationSettingValue vs. web.config

问题描述

我有一个蓝色的工作者角色和一个ASP.NET网站之间共享的类库。库中的一种方法，需要从配置拉一个值，以确定它是否应该发送电子邮件或没有。

I have a class library shared between an Azure Worker Role and a ASP.NET Website. A method in the library needs to pull a value from the config to determine if it should send an email or not.

在ASP.NET网站，设置为在web.config中：

In the ASP.NET site, the setting is in web.config:

<add key="SendEmails" value="true"/>

而在Azure的工作者角色是在ServiceConfiguration.Cloud.cscfg：

And in the Azure worker role it is in ServiceConfiguration.Cloud.cscfg:

<Setting name="SendEmails" value="true"/>

我所试图做的是有我的类库能够访问任何配置设置，取决于其下运行什么样的环境。

What I am trying to do is have my class library be able to access either config setting, depending on what environment it is running under.

推荐答案

创建自己的类来检索配置值，并在其中你就会有这样的内容：

Create your own class to retrieve configuration values and in it you'll have items like this:

if (RoleEnvironment.IsAvailable)
 return RoleEnvironment.GetConfigurationSettingValue("mySetting");
else
 return ConfigurationManager.AppSettings["mySetting"].ToString();

RoleEnvironment.IsAvailable将检测应该是，如果你在Windows Azure结构是检测并返回true。这将要求您在您的ASP.NET项目Microsoft.WindowsAzure.ServiceRuntime装配/参鉴。

RoleEnvironment.IsAvailable will detect is supposed to detect if you're in the Windows Azure fabric and return true. It will require that you include the Microsoft.WindowsAzure.ServiceRuntime assembly/referrence in your ASP.NET project.
