VS 2019 Save text file to disk?

In order to save a text tile to disk in VB.net do I have to use the "SaveFileDialog"?

I've been searching the web for information and can't find anything that works.

What I want to do is something like this:

Open file "c:\Test.txt" for output #1
Write "some text"
Write "Some more text"
Close file #1

Also want to do the same for load file. Is it possible to do this simply? Please give me something that work?

Thanks
