✅ System.IO.IOException Being Thrown

As stated above, a System.IO.IOException is being thrown. I believe it's being thrown because the Streamwriter is trying to write to a file that "doesn't exist", but I am creating the file before that code runs. Any ideas on what could be a solution? Thanks!

        private async Task SaveMessages(bool ForceSave = false)
        {
            Spark.DebugLog(ChatMessages.Count.ToString());
            if (LogMessages || ForceSave && ChatMessages.Count >= 0)
            {
                string FilePath = MessageLogPath + @"\ChatLog   " + DateTime.Now.Day + ";" + DateTime.Now.Month + ";" + DateTime.Now.Year + ".txt";

                if (!System.IO.File.Exists(FilePath))
                {
                    System.IO.File.Create(FilePath);
                }

                await using (StreamWriter sw = new StreamWriter(FilePath))
                {
                    foreach (string Message in ChatMessages)
                    {
                        sw.WriteLine(Message);
                    }
                    sw.Flush();
                }
            }
        }

        private async Task SaveMessages(bool ForceSave = false)
        {
            Spark.DebugLog(ChatMessages.Count.ToString());
            if (LogMessages || ForceSave && ChatMessages.Count >= 0)
            {
                string FilePath = MessageLogPath + @"\ChatLog   " + DateTime.Now.Day + ";" + DateTime.Now.Month + ";" + DateTime.Now.Year + ".txt";

                if (!System.IO.File.Exists(FilePath))
                {
                    System.IO.File.Create(FilePath);
                }

                await using (StreamWriter sw = new StreamWriter(FilePath))
                {
                    foreach (string Message in ChatMessages)
                    {
                        sw.WriteLine(Message);
                    }
                    sw.Flush();
                }
            }
        }

yeah but can you post the exception message?

Kiel•2d ago

you could try using File.OpenWrite instead of just creating an empty file

Kiel•2d ago

using var file = File.OpenWrite(FilePath);
await using var sw = new StreamWriter(file);
...

using var file = File.OpenWrite(FilePath);
await using var sw = new StreamWriter(file);
...

iirc

FumetsuOP•2d ago

Oooh okay I'll have to look into using that, thanks for the help!

Ahhh sorry I'm quite new to this. The exception message must've not been showing because the exception was thrown at the end of the Applications lifetime Anyways Kiel's solution did indeed work, thank you guys for all the help! It seems I still need to brush up on some more documentation..

Ahhh that's alot of stuff to brush up on. Is there a reason why the first word is usually full lowercase? I usually prefer to have all words capitalized Yeahh I kinda just throw alot of stuff together to see if it works first, then I try and come back later to refine it

reason? no, not really. it's about consistency and giving you an easy way to tell at a glance whether a variable name is a Property, _field, or localVariable. in my experience at least

FumetsuOP•2d ago

Ahhh okay yeah that makes sense

Yeah I think I get what you're saying. Currently I have no plans for working with anyone else, but I think it would be better for me to prepare now rather than later When I get the time I'll make sure to go through my code and make it more user friendly
