My.Computer errs

[IlyaRabyy]

Colleagues,
I'm building a class library of common/generic functions I'm going to use in my future projects. Some of them were already used in the projects made in VS 2012 - and worked.
One of them uses My.Computer in the project made in WinForms. Here's the code (part of the function that counts files in the given directory):

For Each lsFile As String In My.Computer.FileSystem.GetFiles(tsDir, lnSubDirs, lcFilePattern)
	lnCnt = lnCnt + 1
Next

I copy-pasted this function from that VS 2012 project into VS 2019 one... and it now gives me this error:

Here's the imports list:

I suspect that My exists only for a form, but I'm not sure. VS 2019 Help search didn't bring any relevant finds...

Q.: what am I missing?
Please advise.

Regards,

Ilya

When you hover over the error what does it suggest?

 

[Andrzejek]

the function that counts files in the given directory

Imports System.IO
...
MessageBox.Show(Directory.GetFiles([blue]"C:\Temp\"[/blue], [blue]"*.txt"[/blue]).Count)

To Andrzejek: yes, the thought did occur. Thank you!

What framework are you targetting?

 

[IlyaRabyy]

To StrongM: anything from .NET 1.0 and higher.

I don't mean, what frameworks are you hoping it will work on; I mean when you created the application what did you set as the target framework?

 

[IlyaRabyy]

Yes, it's .NET 5.0.

Class Library or Windows Application?

IUf the former, try switching it to Windows Application, compiling (which will fail), then switch it back to Class Library.

(make sure you have a backup of your program first though, just in case ... .Net 5 appears fussier about you doing this than previous versions.

 

[IlyaRabyy]

To StrongM: yes, Class Library.
Actually, I went with what Andrzejek suggested.
But I will keep in mind this your suggestion, so - thank you!

Ilya
