How can you check vowel or consonent in vbnet?

You can check if a character is a vowel or a consonant in VB.NET by using a conditional statement with the Char.ToLower() method to ensure case insensitivity. You can then check if the character is a vowel by comparing it to a list of vowels using the Contains() method, and if it is not a vowel, it is considered a consonant.
