Writing to a text file really inneficient [C#] - draxyee - Apr 22, 2020
I'm using this code to write to a text file using many threads at the same time. (Parallel.Foreach a list) with a high thread count.
However, I've noticed that multi thread doesn't increase the speed from a normal foreach when using this method.
PHP Code
<?php
public static void WriteDebug(string pathFile, string text)
{
try
{
locker.AcquireWriterLock(int.MaxValue);
File.AppendAllText(pathFile, text + Environment.NewLine);
}
finally
{
locker.ReleaseWriterLock();
}
}
Is there any other efficient way to output a lot of data to somewhere (preferably to a file)?
I need it to be super super quick.
Cheers

try using streamwriter it might help you

I would strongly advise log4net for this
Code
class Program
{
private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
static void Main(string[] args)
{
log.Info("Hello logging world!");
Console.WriteLine("Hit enter");
Console.ReadLine();
}
}Have a look here > https://stackify.com/log4net-guide-dotnet-logging/

static Streamwriter text = new Steamwriter("file.txt", true);
That line in top of main.
Inside main:
text.Autoflush = true;
text.WriteLine(string);

By default, a StreamWriter is not thread safe.
