❔ if you use a string command in an if command, can you make it case insensitive

so i'm really new to this, and decide to venture a bit away from the tutorial and I want to make it work. So what I have currently is just a basic

Console.Write("Enter your name:");
                string name = Console.ReadLine();

etc. but I'm stuck at a part where I did

Console.Write("Hello " + *name *+ " you are " + *age* + ". is this correct:");
                string *correct* = Console.ReadLine();

                if (*correct *== "YES")
                {
                    Console.WriteLine("Great :D");
                    Console.ReadLine();
                    return;
                }
                if (*correct *== "NO")
                {
                    Console.Write("Do you want to try again?");

The code works, but it's case and space sensitive, which makes it really annoying to answer the question. Is there a fix for this?

I put asterisks around the string names in this message in an attempt at making it easier to read lol just incase it causes confusion

for future reference, it's best to share unmodified code and put it in a code block or on a paste site $paste

If your code is too long, you can post to https://paste.mod.gg/ and copy the link into chat for others to see your shared code!

what's a code block

Jimmacle•2y ago

jouriOP•2y ago

alright hold on

Jimmacle•2y ago

but what you're looking for is the string's Compare method it takes arguments that can let you set it to be case insensitive actually, Equals can do it too

this is the full code.

Jimmacle•2y ago

yeah, so for example you could replace correct == "YES" with correct.Equals("yes", StringComparison.InvariantCultureIgnoreCase)

                        return;

so now I have this, but it doesn't work. Also I think I might be far too new to understand most of this, but it helped a bit so thanks. :D

Jimmacle•2y ago

you have some syntax errors, the condition of an if statement has to be in parentheses for example this is right if (fail == "NO")

jouriOP•2y ago

ah alright, I thought the parentheses were pushed back a bit because of the .Equals. my bad lol Thank you so much for your help @jimmacle I appreciate it a lot.
