Azure的网络/辅助角色读取配置设置 [英] Azure web/worker role read configuration settings

问题描述

什么是从工人/ Web角色读设置的最佳方法/推荐的方式？

What is the best way/recommended way to read settings from a worker/web role?

它是：

CloudConfigurationManager.GetSetting（的ConnectionString）（这我使用）

或

RoleEnvironment.GetConfigurationSettingValue（的ConnectionString）

虽然两者做工精细...

Although both work fine ...

推荐答案

从<一个文档href=\"http://msdn.microsoft.com/en-us/library/microsoft.windowsazure.cloudconfigurationmanager.getsetting.aspx\"><$c$c>CloudConfigurationManager.GetSetting:

该GetSetting方法读取配置与设定值
  适当配置存储。如果应用程序运行为
  .NET Web应用程序中，GetSetting方法将返回设置
  从Web.config或app.config文件的价值。如果该应用程序是
  在Windows Azure云服务或在Windows Azure中运行的网站，
  该GetSetting将返回从设定值
  ServiceConfiguration.cscfg。

The GetSetting method reads the configuration setting value from the appropriate configuration store. If the application is running as a .NET Web application, the GetSetting method will return the setting value from the Web.config or app.config file. If the application is running in Windows Azure Cloud Service or in a Windows Azure Website, the GetSetting will return the setting value from the ServiceConfiguration.cscfg.

从以上，很明显，该函数要么从服务配置文件或应用程序配置文件（的app.config / web.config中），这取决于应用程序正在运行，其中读取，其中如<一个href=\"http://msdn.microsoft.com/en-us/library/microsoft.windowsazure.serviceruntime.roleenvironment.getconfigurationsettingvalue.aspx\"><$c$c>RoleEnvironment.GetConfigurationSettingValue将只从服务配置文件中读取。如果你的应用组件是在云和非云应用中，使用 CloudConfigurationManager.GetSetting ，这样你就不必做了code的任何变化。如果您的组件将在云中只运行，那么我想你可以使用任何一个

From above, it is clear that this function either reads from service configuration file or application configuration file (app.config/web.config) depending on where the application is running where as RoleEnvironment.GetConfigurationSettingValue will only read from service configuration file. If your application component is used in both cloud and non-cloud applications, use CloudConfigurationManager.GetSetting so that you don't have to make any changes in the code. If your component would run only in the cloud, then I guess you could use either one
