You might want to read your ini file duplicate keys into lookup instance.

Something like below might help:

System.IO.StreamReader YourIniFile = new System.IO.StreamReader("yourIniFilePath");
string fileText = YourIniFile.ReadToEnd();  
string[] splitText = fileText.Split(new string[] {"\n", "\r\n"}, StringSplitOptions.RemoveEmptyEntries);
ILookup<string, string> ini = splitText.ToLookup(key=> key.Substring(0, key.IndexOf("=")),
                               value => value.Substring(value.IndexOf("=")));
