我想知道是否有人可以帮助我，我试图将控制台输出保存到文件中，但是它只接受一个输出，并且我希望它每次在控制台中显示时都接受并追加输出（每秒或多或少） ），我尝试了一些不同的方法，但似乎没有任何效果，我甚至不确定是否可行。
1）这是我的第一次尝试：它只需要一个控制台输出，但是据我了解，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）那两个都没有重定向控制台
/*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)
{
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 (StreamReader sr = File.OpenText(path))
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}
// Open the file to read from.
/* using (StreamReader sr = File.OpenText(path))
{
string s;
while ((s = sr.ReadLine()) != null)
{
Console.WriteLine(s);
}
}*/
似乎没有任何正常工作... 我的控制台看起来像这样，相机每移动一次，它都会附加一个值：

但是实际上，我创建的文件只带有第一个值，仅此而已...
答案 0 :(得分：0)
第一次尝试的方法是正确的，但是Console.SetOut是错误的。检查下面编写的代码段：
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");

肮脏的解决方案
将控制台输出存储在一个数组中，然后在关闭应用程序时使用
File.WriteAllLines("path", array);
推荐的解决方案
使用许多日志记录库之一，例如log4net。我在某些项目中独自使用了它，我真的可以推荐它。它还具有一个NuGet软件包，您可以通过右键单击项目通过菜单“管理nuget软件包” 下载。
下面是一个如何使用log4net记录器的小示例
var log=LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
log.Info("Hello World");
此外，您还需要创建一个名称为 log4net.config 的配置文件。在这里，当我从log4net开始时，您有一个使用from this site的配置示例
<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，您需要将此行添加到以下行的 AssemblyInfo.cs 中，以便程序加载配置文件
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config")]
我希望我的遮阳篷能帮上忙
