Do you have experience logging to files for system or application purposes?

Yes, I have experience logging to files for system and application purposes. In C#, this is often done using the StreamWriter class or specialized libraries such as NLog or log4net.

A simple example of logging to a file using StreamWriter:

using System;
using System.IO;

public class Logger
{
    private readonly string logFilePath;

    public Logger(string path)
    {
        logFilePath = path;
    }

    public void Log(string message)
    {
        using (var writer = new StreamWriter(logFilePath, append: true))
        {
            writer.WriteLine($"{DateTime.Now:yyyy-MM-dd HH:mm:ss} - {message}");
        }
    }
}

This approach allows saving logs with timestamps, which is useful for debugging and monitoring application performance.
