Editing a TextAsset in editor independent of build platform

Questions & Answers
1

I’m working on an asset that creates a text file and I don’t want to force the user to change the platform to standalone, so I wouldn’t want to use System.IO.File.CreateText which is only available on Standalone.
I thought AssetDatabase would be the solution but I couldn’t find any tool to edit a TextAsset and every solution I found suggested editing the file using System.IO.File.

Is there a way to edit a text file in editor that is independent of the current build platform?

I found the answer!
I needed to encode it as bytedata and write it that way into the file, here is my code:

        UTF8Encoding tEncod = new UTF8Encoding();
        byte[] tByteData = tEncod.GetBytes(aContent);

        FileStream tFileStream = null;
        if (File.Exists(aPath))
            tFileStream = new FileStream(aPath, FileMode.Open);
        else
            tFileStream = new FileStream(aPath, FileMode.Create);
        tFileStream.Write(tByteData, 0, tByteData.Length);
        tFileStream.Close();

This will work independently of the build platform.

I hope it helps someone.
