DataRow[] dr = new DataRow[dtCampaignSubscriberLists.Rows.Count];
dtCampaignSubscriberLists.Rows.CopyTo(dr, 0);
string[] array = Array.ConvertAll(dr, new Converter<DataRow, String>(????));

string[] array = yourTable

                 .Select(row => row.Field<string>(\"ColumnName\"))

dtCampaignSubscriberLists.AsEnumerable().Select(r => r[0].ToString()).ToArray();
