✅ while loops

while loops keep repeating the same

Console.WriteLine("");

Console.WriteLine("");

over and over without waiting for the user to respond to the

String a = Console.ReadLine();

String a = Console.ReadLine();

anyone know how to solve this?

How to get the best help :catpog: Make a post in #help or one of the topic channels under Development. Avoid asking :catthinking: Can anybody help me? :catthinking: Has anyone used XYZ? :catthinking: Why doesn't my code work? C# is a big area! No one knows they can help unless you tell them about the small area you're trying to work in. Explain what you are doing, and potentially why for as much context as possible. Avoid screenshots where possible, share code directly in Discord. Type $code into chat to learn how to post code. See https://www.nohello.net and https://dontasktoask.com if you want common help chat room etiquette.

Keswiik•2mo ago

^ if you put in an empty name you're gonna get stuck looping forever

how do i not i did in visual studio

Keswiik•2mo ago

the code you just sent has your ReadLine outside of the while loop, so you definitely didn't

TheRanger•2mo ago

code wise i mean

Keswiik•2mo ago

and this is one of the situations where a do-while makes sense

do {
  // your code here to get the name
} while (name is invalid)

do {
  // your code here to get the name
} while (name is invalid)

ohh tysm

Keswiik•2mo ago

I'd also recommend using string.IsNullOrEmpty or string.IsNullOrWhitespace over someString == ""
