在控制台app /中测试的c#代码将无法在服务中工作

我用c#编写了这段代码，它作为一个控制台应用程序工作。但是，当我将代码转换为服务应用程序并使用installutil进行安装时，我无法使其正常工作。此外，控制台不会弹出。将Console.ReadLine ();不参加服务项目?

        Console.ReadLine();

        MySqlDataReader reader = command.ExecuteReader();
        if (reader.HasRows)
        {

            {
                Console.WriteLine(reader["filepath"].ToString());
                SendFax(reader["id"].ToString(), reader["filepath"].ToString(), @"C:'FAXDOC'" + reader["filepath"].ToString(), reader["account"].ToString(), reader["fax"].ToString());
                string id = reader["id"].ToString();
                commandupdate.CommandText = "UPDATE outbox SET `faxpro` = 'DONE' WHERE `id` = '" + id + "'";
                commandupdate.ExecuteNonQuery();
            }
        }

        connupdate.Close();

                FAXCOMLib.FaxServer faxServer = new FAXCOMLib.FaxServerClass();
                faxServer.Connect(Environment.MachineName);

                FAXCOMLib.FaxDoc faxDoc = (FAXCOMLib.FaxDoc)faxServer.CreateDocument(FileName);
                faxDoc.RecipientName = RecipientName;
                faxDoc.FaxNumber = FaxNumber;
                faxDoc.BillingCode = DocumentId;

                int Response = faxDoc.Send();

                faxServer.Disconnect();
            }
            catch (Exception Ex) { Console.WriteLine(Ex.Message); }
        }

    }
}

}

我删除了Console.ReadLine();mysql正在工作，也在更新，但现在SendFax()不工作。没有任何传真正在发送到传真控制台。
