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(',');
