How to convert String to Long in Kotlin?

Answer 1

Actually, 90% of the time you also need to check the 'long' is valid, so you need:

"10".toLongOrNull()

There is an 'orNull' equivalent for each 'toLong' of the basic types, and these allow for managing invalid cases with keeping with the Kotlin? idiom.
