        protected override void OnStop()
        {
            IsTextFileFull(@"C:\Users\family\Documents\Monitor");
        }

        public static bool IsTextFileFull(string fileName)
        {
            int Num_ = byte.MaxValue;
            byte.MaxValue.ToString("3000000"); //3 MegaByte.

            var info = new FileInfo(fileName);
            if (info.Length < Num_)
            {
                var content = File.ReadAllText(fileName);
                return content.Length == 0;
            }
            return true;
        }

    }
}

Maybe this will work:

private void OnCreated(object sender, FileSystemEventArgs e)
{
   string value = $"Created: {e.FullPath}";
   Console.WriteLine(value);

   if( IsTextFileFull(@"C:\Users\family\Documents\Monitor") ) Stop( );
}

public bool IsTextFileFull(string fileName)
{
   var info = new FileInfo(fileName);

   return info.Exists( ) && info.Length > 3_000_000; // (or 3 * 1024 * 1024)
}
