CSV string handling

Question

Typical way of creating a CSV string (pseudocode):

2. Loop through the strings you want to ad

Answer 1

How about some trimming?

public string ReturnAsCSV(ContactList contactList)
{
    StringBuilder sb = new StringBuilder();

    foreach (Contact c in contactList)
    {
        sb.Append(c.Name + ",");
    }

    return sb.ToString().Trim(',');
}
