Is use of?? when checking a null using null-coalescing operator and there is??= in C# 8.0. There is the same functionality behavior and what is the advantage of using ==? operator.
int? a = null;
int b = 10;
a = a ??= 0;
a = a ?? b;
What is "bad practice" is highly opinionated, but in this case, not really.
The new operator ??=
only replaces the common case of a = a?? b
a = a?? b
.
There are still many other users for ??
, eg if (a?.Foo()?? false)
or Foo(a?? 0)
or var c = a?? b
var c = a?? b
etc.
