I've been using C# for around 8 years now but still I'm unaware of few conditional checks that we use frequently such as !string.IsNullOrEmpty. Can anyone help how can I over such tricks or any link where I can learn all such tricks. I know we all use AI for coding now. But still I love to code myself and wanna be a pro. I'd be grateful if someone can guide me over this.

Best regards,
Caroline
