How to make/write to files, then read immediately?

Questions & Answers
1

I’ve been having trouble with reading files immediately after I have made them within Javascript. Even when I have done Directory.CreateDirectory(filepath), then check with File.Exists(filepath), it returns false. Is there some kind of refresh function I need to call to refresh the files? I am storing to Application.persistentDataPath.

I have tried methods from this thread:

but to no avail.

Thanks in advance.

Well, the problem could be that the filehandle isn’t released immendiately. In C# you usually out the file object in a using statement. This will invoke the IDisposable interface of the file object and should release the filehandle once you left the using block. I thought that the Close function does the same thing, but i could be wrong.

In C# it would look like this:

// [...]
using(StreamWriter sw = new StreamWriter(filepathIncludingFileName))
{
    sw.WriteLine("Line to write");
    sw.WriteLine("Another Line");
    sw.Flush();
    sw.Close();
}
// Here it should be closed and freed.

I’m not sure if UnityScript supports the using block in some way. Since it’s a non-standard language it’s hard to tell.

edit
In UnityScript it might help when you call Dispose(); manually:

// UnityScript
var sw = new StreamWriter(filepathIncludingFileName)
sw.WriteLine("Line to write");
sw.WriteLine("Another Line");
sw.Flush();
sw.Close();

sw.Dispose();
