using -@ ARGFILE throws INVALID TAG error

[nemethviktor]

Hi there,

I'm trying to use an arguments file for writing tags with exiftool/ASET. The file contents is set up okay and when executing from traditional cmd (just using exiftool -@ exifArgs.args d:\temp\sample1.pef it's working fine.
When I use the logic var result = await asyncExifTool.ExecuteAsync(new[] { "-@ exifArgs.args", Path.Combine(folderName, lvi.Text) }); or any version of var exifToolCommand = new[] { "-@ exifArgs.args" }; the script throws an invalid tag error.
How do I overcome this?
Thanks

ps i've enabled logging.:

Hi, i'm not sure if and how this works with argument files. I didn't used them at the time.

No worries. I ended up figuring it out -> instead of putting the arg file into the array of elements it needs to be faked to be a long element.
As in not

[0] = -something 
[1] = -@ args

but instead:
[0] = "-something - @ args"
