从ncftpput.exe重定向标准/错误输出不稳定

我正试图从ncftpput.exe获得输出流，并能够异步地操纵流。Ncftpput.exe不逐行打印它的流，相反，它只是用新信息更新同一行(这可能是相关的)。它断断续续地工作——有时我能得到信息，有时不能。

本质上，是否有一种方法可以让一个流刷新它的行频繁重定向在一个更安全和有规律的方式?

这是我目前得到的(我已经注释了它，去掉了不相关的无关信息，但这是本质):

class Program
{
    static int main()
    {
        internal Process m_Tool { get; set; }
        internal ProcessStartInfo m_StartInfo { get; set; }
        internal static string m_StandardData { get; set; }
        internal static string m_ErrorData { get; set; }
        m_Tool = new Process();
        m_StartInfo = new ProcessStartInfo();
        m_StartInfo.FileName = @"C:'utils'ncftpput.exe";
        m_StartInfo.UseShellExecute = false;
        m_StartInfo.RedirectStandardOutput = true;
        m_StartInfo.RedirectStandardError = true;
        m_StandardData = "";
        m_ErrorData = "";
        m_StartInfo.Arguments = /* Various starting args */
        m_Tool.StartInfo = m_StartInfo;
        m_Tool.Start();
        string standardLine;
        string errorLine;
        try
        {
            m_Tool.OutputDataReceived += ProcessStandardDataHandler;
            m_Tool.ErrorDataReceived += ProcessErrorDataHandler;
            m_Tool.BeginErrorReadLine();
            m_Tool.BeginOutputReadLine();
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
        while (!m_Tool.HasExited)
        {
            System.Threading.Thread.Sleep(5000);
            standardLine = m_StandardData;
            errorLine = m_ErrorData;
        } 
    }
    private static void ProcessErrorDataHandler(object sendingProcess, DataReceivedEventArgs outLine)
    {
        if (!String.IsNullOrEmpty(outLine.Data))
        {
            // Add the text to the collected output.
            m_ErrorData = outLine.Data.ToString();
            m_DataReceived = true;
        }
    }
    private static void ProcessStandardDataHandler(object sendingProcess, DataReceivedEventArgs outLine)
    {
        if (!String.IsNullOrEmpty(outLine.Data))
        {
            // Add the text to the collected output.
            m_StandardData = outLine.Data.ToString();
        }
    }
}

提前感谢!!
