?? Null-Coalescing Operator C# with Example
The Null-Coalescing operator ?? will return the left-hand side when not null. If it is null, it will return the right-hand
object foo = null;
object bar = new object();
var c = foo ?? bar;
//c will be bar since foo was null
The ?? operator can be chained which allows the removal of if checks.
//config will be the first non-null returned.
var config = RetrieveConfigOnMachine() ??
