I use that one

catch (Exception e)
{
    new MessageWriteToFile(e).WriteToFile();
}


public class MessageWriteToFile
{
    private const string Directory = "C:\\AppLogs";
    public string Message { get; set; }
    public Exception Exception { get; set; }
    public string DefaultPath
    {
        get
        {
            var appName = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name;
            var folder = $"{Directory}\\{appName}";

            if (!System.IO.Directory.Exists(folder))
            {
                System.IO.Directory.CreateDirectory(folder);
            }

            var fileName = $"{DateTime.Today:yyyy-MM-dd}.txt";
            return $"{Directory}\\{appName}\\{fileName}";
        }
    }

    public MessageWriteToFile(string message)
    {
        Message = message;
    }

    public MessageWriteToFile(Exception ex)
    {
        Exception = ex;
    }

    public bool WriteToFile(string path = "")
    {
        if (string.IsNullOrEmpty(path))
        {
            path = DefaultPath;
        }

         try
        {
            using (var writer = new StreamWriter(path, true))
            {
                writer.WriteLine("-----------------------------------------------------------------------------");
                writer.WriteLine("Date : " + DateTime.Now.ToString(CultureInfo.InvariantCulture));
                writer.WriteLine();

                if (Exception != null)
                {
                    writer.WriteLine(Exception.GetType().FullName);
                    writer.WriteLine("Source : " + Exception.Source);
                    writer.WriteLine("Message : " + Exception.Message);
                    writer.WriteLine("StackTrace : " + Exception.StackTrace);
                    writer.WriteLine("InnerException : " + Exception.InnerException?.Message);
                }

                if (!string.IsNullOrEmpty(Message))
                {
                    writer.WriteLine(Message);
                }

                writer.Close();
            }
        }
        catch (Exception)
        {
            return false;
        }

        return true;
    }
}
