Hi I would like to take a list collection and generate a single csv line. So take this;

List<string> MakeStrings()
{
    List<string> results = new List<string>();
    results.add("Bob");
    results.add("Nancy");
    results.add("Joe");
    results.add("Jack");       
}


string ContactStringsTogether(List<string> parts)
{
    StringBuilder sb = new StringBuilder();

    foreach (string part in parts)
    {
        if (sb.Length > 0)
            sb.Append(", ");

        sb.Append(part);
     }
     return sb.ToString();
}

This returns "Bob,Nancy,Joe,Jack"

Looking for help on the LINQ to do this in a single statement. Thanks!
