如何从应用程序级别使用Azure中的服务配置？

Question

I have some cloud service implemented in C#. Whole solution consists of Service Project with some settings, separate projects for multiple roles + one separate project with main logic of the application. Now, I need to distinguish application url depending on environment it is run on. I know (suspect might be better choice of words) I can modify ServiceConfiguration.<Cloud|Local>.cscfg file by adding <Setting name="domain" value="example.com" />

Now, the question I'd like to ask is: how can access this configuration value from source code?

Answer 1

Yes, it is certainly possible. So if you have a cloud project A and that has a setting <Setting name="domain" value="exampleA.com" /> and then you have cloud project B that has a setting <Setting name="domain" value="exampleB.com" /> and then you have main project which is used in both cloud projects A and B.

When you run project A and read the setting domain from your main project you will get exampleA.com and when you run project B and read the same setting, you will get exampleB.com .

Answer 2

I added to the ServiceConfigurationCloud.cscfg and the ServiceConfigurationLocal.cscfg

<ConfigurationSettings>
<Setting name="DataBaseConnectionString" value="Data Source=MYNAME.database.windows.net;Initial Catalog=MYDATABASE;Persist Security Info=True;User ID=USERNAME;Password=PASSWORD"/>
</ConfigurationSettings>

Then I added to the ServiceDefinition.csdef file.

<ConfigurationSettings>
  <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" />
  <Setting name="DataBaseConnectionString"/>
</ConfigurationSettings>

Within the code I was able to read from the file by using

string DBCO = RoleEnvironment.GetConfigurationSettingValue("DataBaseConnectionString");
