✅ *"Converting possible null value to non nullable type"* warning in `Console.ReadLine()`
Can I ignore "Converting possible null value to non nullable type" warning here:
I have never faced any runtime errors even when entering nothing on Console. Seems like an unnecessary warning.
Sory for the dumbest question ever :catderp:

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.https://learn.microsoft.com/en-us/dotnet/api/system.console.readline?view=net-9.0#remarks just declare it as a nullable by doing
string? s = Console.ReadLine();
basically it means that it can be assigned a null value - which ReadLine may returnOk so, I was doing null check
string.IsNullOrWhiteSpace() before returning string to my Main method that's why I was not able to generate Null Reference Exception. whether I declare string s or string? s
Yes
Thank you both for infoYou can handle it very easily, fwiw
