?? Null-Coalescing Operator
suggest changeThe Null-Coalescing operator ??
will return the left-hand side when not null. If it is null, it will return the right-hand side.
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() ??
RetrieveConfigFromService() ??
new DefaultConfiguration();
Found a mistake? Have a question or improvement idea?
Let me know.
