Converting null literal or possible null value to non-nullable type.

Hey all real quick question, am still trying to learn c# and am getting a warning when using Console.ReadLine(), if anyone could explain real quick i would greatly appreciate it, thanks!

No idea, honestly. It seems perfectly fine to me

MathallOP•6/25/24, 12:06 AM

see the weird part is that without the ?? "Test", the whole Console.ReadLine()Console.ReadLine() has a warning

MathallOP•6/25/24, 12:06 AM

but with it, only the console part has a warning

Angius•6/25/24, 12:06 AM

Yes, because it returns a string?string? not a

string

string

MathallOP•6/25/24, 12:06 AM

yes i understand that

Angius•6/25/24, 12:07 AM

And it really doesn't make sense for just the ConsoleConsole to be highlighted

MathallOP•6/25/24, 12:07 AM

exactly

Angius•6/25/24, 12:07 AM

Try restarting (I assume) VS Code?

MathallOP•6/25/24, 12:07 AM

i have and the warning remains

Angius•6/25/24, 12:09 AM

Weird

MathallOP•6/25/24, 12:09 AM

so its definitely a vscode issue, becuase i input the same code into visual studio and no warning

VSCode has always been subpar C# experience

Buddy•6/25/24, 12:11 AM

Some say VSCode is great .. they are lying

Buddy•6/25/24, 12:11 AM

Mostly because the plugins are god awful and breaks constantly

Petris•6/25/24, 12:20 AM

not for C# at least

Petris•6/25/24, 12:20 AM

but Rust from what I've heard works best there

Buddy•6/25/24, 12:21 AM

It does, yes.
Sadly RustRover is way too unstable and demanding.

MMathall i have and the warning remains

Do you get the warning when you run dotnet builddotnet build

It would be great if you could not make things up

MMathall Hey all real quick question, am still trying to learn c# and am getting a warnin...

doesnt when you put nothing in the console it just an empty string?

Documentation to the rescue! https://learn.microsoft.com/en-us/dotnet/api/system.console.readline?view=net-8.0#remarks

If the Ctrl+Z key combination (followed by Enter on Windows) is pressed when the method is reading input from the console, the method returns null. This enables the user to prevent further keyboard input when the ReadLine method is called in a loop

canton7•6/25/24, 8:18 AM

If the input stream is closed, then Console.ReadLineConsole.ReadLine returns null

sashimikitty•6/25/24, 8:32 AM

ah i see

the idk why this script doesnt work

sashimikitty•6/25/24, 8:33 AM

this seems weird did you fix it yet?

sashimikitty•6/25/24, 8:34 AM

or maybe try using a "string?" instead of a normal string
