foreach (IGrouping<char, string> packageGroup in lookup)
{
    // Print the key value of the IGrouping.
    Console.WriteLine(packageGroup.Key);
    // Iterate through each value in the IGrouping and print its value.
    foreach (string str in packageGroup)
        Console.WriteLine("    {0}", str);
