What does ConfigurationManager.AppSettings do?

My current understanding is that it making a call to something in my config file and returning data. I am not clear what the parameters are for ConfigurationManager.AppSettings are.

I have looked through this documentation (https://msdn.microsoft.com/en-us/library/1xtk877y%28v=vs.110%29.aspx) but don't quite understand it.

For context this is the code I'm working with: 

    string code1 = ConfigurationManager.AppSettings[string1 + string2];
    string code2 = ConfigurationManager.AppSettings[string3];
    string query = new BuildMDXQuery(cube).BuildFetchInventoryQuery(code1, code2);

I'd like to know how I can find what's getting called in my config file, if anything, and what the purpose of using ConfigurationManager.AppSettings is. Thanks!

It reads from the appSettings section of the config file, so...

Configuration.AppSettings["Whatever"]

...would return "Blah" in the case of:

<configuration>
    <appSettings>
        <add key="Whatever" value="Blah" />
    </appSettings>
</configuration>
