如何在处理WinSCPnet.dll FileTransferProgress时在SSIS脚本任务中使用DTS.Events.FireInformation()？

using WinSCP;

namespace ST_XXXXXXXXXXXXXXXXXXXXXXXX
{
    public class ScriptMain : UserComponent
    {
        public override void PreExecute()
        {
            base.PreExecute();
        }

        public override void PostExecute()
        {
            base.PostExecute();
        }

        public override void Input0_ProcessInputRow(Input0Buffer Row)
        {
            base.Input0_ProcessInputRow(Row);
        }

        public override void CreateNewOutputRows()
        {
            try
            {
                // 创建会话选项
                SessionOptions sessionOptions = new SessionOptions
                {
                    Protocol = Protocol.Sftp,
                    HostName = "your_hostname",
                    UserName = "your_username",
                    Password = "your_password"
                };

                // 创建会话对象并注册FileTransferProgress事件处理程序
                Session session = new Session();
                session.FileTransferProgress += SessionFileTransferProgress;

                // 连接到远程服务器并开始文件传输
                session.Open(sessionOptions);
                session.GetFiles("/remote/path/*.txt", "C:\\local\\path\\").Check();
            }
            catch (Exception ex)
            {
                // 处理异常情况
                Dts.Events.FireError(0, "WinSCP Error", ex.Message, string.Empty, 0);
            }
        }

        private void SessionFileTransferProgress(object sender, FileTransferProgressEventArgs e)
        {
            // 获取传输进度信息
            double progressPercentage = e.FileProgress * 100.0;

            // 使用DTS.Events.FireInformation()方法进行日志记录
            Dts.Events.FireInformation(0, "WinSCP Progress", $"Transferred: {progressPercentage}%", string.Empty, 0, ref fireAgain);
        }
    }
}
