Multiple values for a single config key

Question

I'm trying to use ConfigurationManager.AppSettings.GetValues() to retrieve multiple configuration values for a single key, but I'm always receiving an array of only the last value. My appsettings.config looks like

<add key="mykey" value="A"/> <add key="mykey" value="B"/> <add key="mykey" value="C"/> 

and I'm trying to access with

ConfigurationManager.AppSettings.GetValues("mykey"); 

but I'm only getting { "C" }.

Any ideas on how to solve this?

Answer 1

Try

<add key="mykey" value="A,B,C"/> 

And

string[] mykey = ConfigurationManager.AppSettings["mykey"].Split(',');
