如何在.cscfg文件中为Windows Azure-worker角色设置数据库连接字符串？

Question

Have to set the Database connection string in the .cscfg file, not the app.config (In my windows azure worker role application). Can anyone help me on this..?

Thanks in Adavance. Cheers.

If you're thinking about setting the connection string in <connectionStrings></connectionStrings> element in .cscfg file, you can't do that. Configuration file only takes name/value pair. So you would do something like:

<?xml version="1.0"?>
<ServiceConfiguration serviceName="Web.Azure" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="3" osVersion="*" schemaVersion="2013-03.2.0">
  <Role name="Worker">
    <Instances count="2" />
    <ConfigurationSettings>
      <Setting name="DatabaseConnectionString" value="your database connection string" />
    </ConfigurationSettings>
  </Role>
</ServiceConfiguration>

and then read the connection string in your code like:

var databaseConnectionString = RoleEnvironment.GetConfigurationSettingValue("DatabaseConnectionString")

and use that connection string for your database calls.
