Accepted answer
You can use String.Trim method like this:-
first.SetField("SameReferences", string.Format("{0},{1}", duplicate,
first.Field<string>("SameReferences")).Trim(','));
It will remove all the trailing comma.

Try this:
if (first.Field<string>("SameReferences") != null)
{
string duplicate = first.Field<int>("SortOrder").ToString();
string sameReference = first.Field<string>("SameReferences");
if (String.IsNullOrEmpty(sameReference))
first.SetField("SameReferences", duplicate);
else
first.SetField("SameReferences", string.Format("{0},{1}", duplicate, sameReference));
}
