Console.WriteLine为空

Posted 2021-04-19

我有一个奇怪的问题。我写了一个在Windows Server 2008 R2上运行的.net 2.0控制台应用程序，它处理一个通过args传入的文件。当我手动运行它并传入一个文件时，我没有得到输出。没有。没有错误或任何类型的例外。事件日志很清楚。我希望我从exe获得一些输出。我的Console.WriteLine声明中也有一个catch。但同样，没有任何输出。有什么想法吗？

namespace RTDXCentralFileTransmit
{
    class Program
    {
        static void Main(string[] args)
        {

            try
            {
                if (args.Length < 1)
                {
                    Console.WriteLine("File name is required");
                    logit("File name is required");
                    return;
                }
                string filename = args[0];

                Console.WriteLine("Now doing " + filename);
                logit("Now doing " + filename);

                if (!File.Exists(filename))
                {
                    Console.WriteLine("File " + filename + " does not exists.  Exiting.");
                    logit("File " + filename + " does not exists.  Exiting.");
                    File.WriteAllText("Error.txt", "File " + filename + " does not exists.  Exiting.");
                    return;
                }

                string fileplain = File.ReadAllText(filename);
                string file64 = EncodeTo64(fileplain);

                if (string.IsNullOrEmpty(file64))
                {
                    Console.WriteLine("File " + filename + " is empty.  Exiting");
                    logit("File " + filename + " is empty.  Exiting");
                    File.WriteAllText("Error.txt", "File " + filename + " is empty.  Exiting");
                    return;
                }

                FileInfo fi = new FileInfo(filename);

                com.xxxxxxxxxxxxxxxxxx.api.Dispatch dis = new com.xxxxxxxxxxxxxxxx.api.Dispatch();
                com.xxxxxxxxxxxx.api.FunnelResult fr = dis.Funnel(file64, fi.Name);

                if (fr.Success)
                {
                    Console.WriteLine("Success! " + fr.Result);
                    logit("Success!  Response from the server: " + fr.Result);
                    File.WriteAllText("Success.txt", fr.Result);
                    return;
                } else
                {
                    Console.WriteLine("Failed!! " + fr.Result);
                    logit("Failed!! " + fr.Result);
                    File.WriteAllText("Error.txt", "Transmission Failed! " + fr.Result);
                }
                logit("Exiting for " + filename);
                Environment.Exit(0);

            } catch (Exception e)
            {
                Console.WriteLine("Error. " + e.ToString());
                return;
            }

        }

        static void logit (string s)
        {
            File.AppendAllText("FileTransmit.log",DateTime.Now.ToString() + ":" + s + Environment.NewLine);
        }

        static public string EncodeTo64(string toEncode)
        {
            byte[] toEncodeAsBytes
                  = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode);
            string returnValue
                  = System.Convert.ToBase64String(toEncodeAsBytes);
            return returnValue;
        }
    }
}

答案

我找到了。问题出在主席和电脑之间。

我克隆的项目，即使它有大量的Console.WriteLine，它实际上是被构建为Windows Application.这解释了为什么我们没有为Console.WriteLine.输出

由于它是作为windows application构建的，因此控制台不会等待程序完成。它立即返回 - 这让我完全不再看到许多console.writelines。但是，程序仍在运行，并且对于大文件，将其发布到远程服务器需要一段时间。等待一两分钟后，所有10 MB文件都成功传输，因为它在日志中显示。
