How to discrete a string with "," or ";" and placing txts/vals in different controls

[pourkascheff]

Hello everyone! Sorry, this topic may be repetitious but I'm stuck deeply when I need to close a project the most.

Here's the thing. Consider a long string in a notepad.txt file as shown below:
"Last Name, First name, Gender, Age, Email, Phone number, blank, [so many other parameters]"

Previously I used DataGridView and *.csv files which do the same but I need to use those datas in different controls.

Edit: I heard somewhere Visual Studio libraries will do the matter with simpler method/functions like "remove" and "split" commands. But the problem is I have no idea how to use them...
