The following solution provided is one of many possible solutions.

string orderStream = "B123,C234,A345,C15,B177,G3003,C235,B179";
string[] items = orderStream.Split(',');
Array.Sort(items);

foreach (var item in items)
{
    if (item.Length == 4)
    {
        Console.WriteLine(item);
    }
    else
    {
        Console.WriteLine(item + "\t- Error");
    }
}

This code is merely "one possible solution." As long as your output matches the following, you succeeded.

A345
