Getting user profile values that support multiple value

I noticed today that the MSDN article "User Profiles Object Model Overview" has a wrong code sample for the "correct way of retrieving a user profile property value". The code sample there will not work, because the object model in sharepoind doesnt have the methods and objects the sample code is using.
Therefore - here is my correct way:

if (Profile[this.UserProfilePropertyName].Count == 1)
    return Profile[this.UserProfilePropertyName].Value.ToString();
else
{
    StringBuilder ret = new StringBuilder("");
    UserProfileValueCollection values = Profile[this.UserProfilePropertyName];
    System.Collections.IEnumerator allValues = values.GetEnumerator();
    while(allValues.MoveNext())
    {
        ret.Append(allValues.Current.ToString());
        ret.Append(";");
    }
    return ret.ToString();
}
