如何将Console.WriteLine输出保存到文本文件

Question

我有一个程序,可以将各种结果输出到命令行控制台.

如何使用StreamReader其他技术将输出保存到文本文件？

System.Collections.Generic.IEnumerable<String> lines = File.ReadAllLines(@"C:\Test\ntfs8.txt");

foreach (String r in lines.Skip(1))
{
    String[] token = r.Split(',');
    String[] datetime = token[0].Split(' ');
    String timeText = datetime[4];
    String actions = token[2];
    Console.WriteLine("The time for this array is: " + timeText);
    Console.WriteLine(token[7]);
    Console.WriteLine(actions);
    MacActions(actions);
    x = 1;
    Console.WriteLine("================================================");
}

if (x == 2)
{
    Console.WriteLine("The selected time does not exist within the log files!");
}

System.IO.StreamReader reader = ;
string sRes = reader.ReadToEnd();
StreamWriter SW;
SW = File.CreateText("C:\\temp\\test.bodyfile");
SW.WriteLine(sRes);
SW.Close();
Console.WriteLine("File Created");
reader.Close();

从本文中尝试此示例 - 演示将控制台输出重定向到文件

using System;
using System.IO;

static public void Main ()
{
    FileStream ostrm;
    StreamWriter writer;
    TextWriter oldOut = Console.Out;
    try
    {
        ostrm = new FileStream ("./Redirect.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;
    }
    Console.SetOut (writer);
    Console.WriteLine ("This is a line of text");
    Console.WriteLine ("Everything written to Console.Write() or");
    Console.WriteLine ("Console.WriteLine() will be written to a file");
    Console.SetOut (oldOut);
    writer.Close();
    ostrm.Close();
    Console.WriteLine ("Done");
}

Answer 2

尝试这是否有效:

FileStream filestream = new FileStream("out.txt", FileMode.Create);
var streamwriter = new StreamWriter(filestream);
streamwriter.AutoFlush = true;
Console.SetOut(streamwriter);
Console.SetError(streamwriter);

对于这个问题:

如何将Console.Writeline输出保存到文本文件？

我会Console.SetOut像其他人提到的那样使用.

但是,它看起来更像是在跟踪您的程序流程.我会考虑使用Debug或Trace跟踪程序状态.

它的工作原理类似于控制台,除了您可以更好地控制输入,例如WriteLineIf.

Debug只有在调试模式下Trace才会运行,因为它将在调试或释放模式下运行.

它们都允许输出文件或控制台等监听器.

TextWriterTraceListener tr1 = new TextWriterTraceListener(System.Console.Out);
Debug.Listeners.Add(tr1);

TextWriterTraceListener tr2 = new TextWriterTraceListener(System.IO.File.CreateText("Output.txt"));
Debug.Listeners.Add(tr2);

你想为此编写代码还是只使用命令行功能'命令重定向',如下所示:

app.exe >> output.txt

如下所示:http://discomoose.org/2006/05/01/output-redirection-to-a-file-from-the-windows-command-line/(存档于archive.org)

基于 WhoIsNinja 的回答：

此代码将输出到控制台和日志字符串中，该字符串可以通过向其附加行或覆盖它来保存到文件中。

日志文件的默认名称为“Log.txt”，并保存在应用程序路径下。

public static class Logger
{
    public static StringBuilder LogString = new StringBuilder();
    public static void WriteLine(string str)
    {
        Console.WriteLine(str);
        LogString.Append(str).Append(Environment.NewLine);
    }
    public static void Write(string str)
    {
        Console.Write(str);
        LogString.Append(str);

    }
    public static void SaveLog(bool Append = false, string Path = "./Log.txt")
    {
        if (LogString != null && LogString.Length > 0)
        {
            if (Append)
            {
                using (StreamWriter file = System.IO.File.AppendText(Path))
                {
                    file.Write(LogString.ToString());
                    file.Close();
                    file.Dispose();
                }
            }
            else
            {
                using (System.IO.StreamWriter file = new System.IO.StreamWriter(Path))
                {
                    file.Write(LogString.ToString());
                    file.Close();
                    file.Dispose();
                }
            }               
        }
    }
}

然后你可以像这样使用它：

Logger.WriteLine("==========================================================");
Logger.Write("Loading 'AttendPunch'".PadRight(35, '.'));
Logger.WriteLine("OK.");

Logger.SaveLog(true); //<- default 'false', 'true' Append the log to an existing file.

创建一个类 Logger（代码如下），用 Logger.Out 替换 Console.WriteLine。最后将字符串 Log 写入文件

public static class Logger
{        
     public static StringBuilder LogString = new StringBuilder(); 
     public static void Out(string str)
     {
         Console.WriteLine(str);
         LogString.Append(str).Append(Environment.NewLine);
     }
 }
