✅ New to c# using Visual studio(WindowsFormsApp)
Hi everyone I've been trying to code something, if u put a sentence in a text box and u click a button that it will automatically put all vowels in capital letters in another text box and then all Consonants in capital letters in another text box. Can anyone help me with this code? Tell me what I did wrong, give me a code I can use or any help would be appreciated!
