Unique ways to use the null coalescing operator [closed]

Answer 1

One thing I've been doing a lot lately is using null coalescing for backups to as. For example:

object boxed = 4;
int i = (boxed as int?) ?? 99;

Console.WriteLine(i); // Prints 4

It's also useful for backing up long chains of ?. that could each fail

int result = MyObj?.Prop?.Foo?.Val ?? 4;
string other = (MyObj?.Prop?.Foo?.Name as string)?.ToLower() ?? "not there";
