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 o

Answer 1

I use naming convention of the keys and it works like a charm

var section1 = ConfigurationManager.GetSection("section1") as NameValueCollection;
for (int i = 0; i < section1.AllKeys.Length; i++)
{
    //if you define the key is unique then use == operator
    if (section1.AllKeys[i] == "keyName1")
    {
        // process keyName1
    }

    // if you define the key as a list, starting with the same name, then use string StartWith function
    if (section1.AllKeys[i].Startwith("keyName2"))
    {
        // AllKeys start with keyName2 will be processed here
    }
}
