无法从本地驱动器读取配置文件数据

Question

I fail to read the appSettings from a config file. It is not located in the default location so when I tried using var aWSAccessKey = ConfigurationManager.AppSettings["AWSAccessKey"]; it didn't work.

Config file:

<appSettings>
    <add key="AWSAccessKey" value="1" />
    <add key="AWSSecretKey" value="2" />
    <add key="AWSRegion" value="4" />
    <add key="AWSAccountNumber" value="5" />
</appSettings>

Also tried with no success:

var fileMap = new ConfigurationFileMap("D:AWS\\CoreLocalSettings.config");
var configuration = ConfigurationManager.OpenMappedMachineConfiguration(fileMap);
var sectionGroup = configuration.GetSectionGroup("applicationSettings");

Answer 1

Finally it's working:

In the app.config file I read the outside config file data as below

<configuration>
    <appSettings file="D:\AWS\CoreLocalSettings.config">
    .......
    </appSettings>
</configuration>

In the code base I am accessing same using the ConfigurationManager

var strAWSAccessKey = ConfigurationManager.AppSettings["AWSAccessKey"];
