如何将控制台输出保存到文件?

我想知道是否有人可以帮助我,我试图将我的控制台输出保存到一个文件,但它只需要一个输出,我希望它每次在控制台中显示时附加输出(或多或少每秒),我尝试了一些不同的方法,但似乎没有任何工作,我甚至不确定这是否可行 .

1)这是我的第一次尝试:它只需要一个控制台输出,但据我所知,它应该重定向它 .

FileStream ostrm;
                StreamWriter writer;
                TextWriter oldOut = Console.Out;
                try
                {
                    ostrm = new FileStream("C:/Users/Joanne/Desktop/WriteLines3.txt", FileMode.OpenOrCreate, FileAccess.Write);
                    writer = new StreamWriter(ostrm);
                }
                catch (Exception e)
                {
                    Console.WriteLine("Cannot open Redirect.txt for writing");
                    Console.WriteLine(e.Message);
                    return;
                }
                while(onvifPTZ != null) { 
                Console.SetOut(writer);
                Console.WriteLine("\t Act Value [" + curPan.ToString() +
                                                       "," + curTilt.ToString() +
                                                       "," + curZoom.ToString() + "]");
                Console.WriteLine("\t Ref Value [" + newPTZRef.pan.ToString() +
                                                       "," + newPTZRef.tilt.ToString() +
                                                       "," + newPTZRef.zoom.ToString() + "]");
                Console.WriteLine("\t Dif Value [" + dPan.ToString() +
                                                   "," + dTilt.ToString() +
                                                   "," + dZoom.ToString() + "]");
                Console.SetOut(oldOut);
                writer.Close();
                ostrm.Close();
                Console.WriteLine("Done");

2)那两个没有重定向控制台

/*while (onvifPTZ != null)
                {


                    string[] lines = {"\t Act Value [" + curPan.ToString() +
                                                       "," + curTilt.ToString() +
                                                       "," + curZoom.ToString() + "]","\t Ref Value [" + newPTZRef.pan.ToString() +
                                                       "," + newPTZRef.tilt.ToString() +
                                                       "," + newPTZRef.zoom.ToString() + "]", "\t Dif Value [" + dPan.ToString() +
                                                   "," + dTilt.ToString() +
                                                   "," + dZoom.ToString() + "]" + Environment.NewLine };

                        string mydocpath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

                    using (StreamWriter outputFile = new StreamWriter(Path.Combine(mydocpath, "WriteLines1.txt")))
                    {
                        foreach (string line in lines)
                            outputFile.WriteLine(line);
                        outputFile.Flush();
                    }

3)

/* string path = @"c://Users//Joanne//Desktop//WriteLines.txt";

                   if (!File.Exists(path))
                   {
                       // Create a file to write to.
                      using (StreamWriter sw = File.CreateText(path))
                       {
                           while(onvifPTZ!=null){ 
                           sw.WriteLine("\t Act Value [" + curPan.ToString() +
                                                          "," + curTilt.ToString() +
                                                          "," + curZoom.ToString() + "]");
                           sw.WriteLine("\t Ref Value [" + newPTZRef.pan.ToString() +
                                                          "," + newPTZRef.tilt.ToString() +
                                                          "," + newPTZRef.zoom.ToString() + "]");
                           sw.WriteLine("\t Dif Value [" + dPan.ToString() +
                                                      "," + dTilt.ToString() +
                                                      "," + dZoom.ToString() + "]");
                               sw.Flush();
                               //sw.Close();
                           }
                       }
                   }


                  /*using (StreamWriter sw = File.AppendText(path)) {
                           while (onvifPTZ != null)

                                                              "," + curZoom.ToString() + "]");
                               sw.WriteLine("\t Ref Value [" + newPTZRef.pan.ToString() +

似乎没有什么工作正常...我的控制台看起来像这样,对于相机所做的每一次移动都会附加一个值:

但实际上我创建的文件只占用第一个值,仅此而已......

    Dirty solution
    将控制台输出存储在一个数组中,当您关闭应用程序时,将其存储在一个数组中

    File.WriteAllLines("path", array);
    

    Recommended solution
    使用许多日志库之一,如log4net . 我自己在一些项目中使用它,我真的可以推荐它 . 它还有一个NuGet包,您可以通过右键单击项目通过菜单"manage nuget packages"下载 .

    这里有一个小例子如何使用log4net Logger

    var log=LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
    
    log.Info("Hello World");
    

    您还需要创建名为 log4net.config 的配置文件 . 这里有一个我使用from this site的配置示例,当我开始使用log4net时

    <log4net>
    <root>
      <level value="ALL" />
      <appender-ref ref="console" />
      <appender-ref ref="file" />
    </root>
    <appender name="console" type="log4net.Appender.ConsoleAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date %level %logger - %message%newline" />
      </layout>
    </appender>
    <appender name="file" type="log4net.Appender.RollingFileAppender">
      <file value="myapp.log" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="5" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
      </layout>
    </appender>
    </log4net>
    

    最后你需要将这一行添加到 AssemblyInfo.cs 以下行,程序加载配置文件

    [assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config")]
    

    我希望我的awnser很有帮助

    第一次尝试的方法是正确的,但您的Console.SetOut是错误的 . 检查下面的代码:

    using (var ostrm = new FileStream("C:/Users/dervis.kayimbasioglu/Desktop/WriteLines3.txt", FileMode.OpenOrCreate, FileAccess.Write))
    using (var writer = new StreamWriter(ostrm))
    {
        Console.SetOut(writer);
        Console.WriteLine("test to be written in file");
        writer.Close();
        ostrm.Close();
    }
    
    Console.WriteLine("Done");
