More C# syntactic sugar
First up, the “??” uperator. You’ll probably suspect that this is related to the ?= ternary operator, and you’d be right. The ?? operator is called the null-coalescing operator. Not a very meaningful name, but here’s what it does.
1 | foo = bar ?? baz; |
is equivalent to:
1 | foo = (bar != null) ? bar : baz; |
and also to this, which I usually write because I find the ternary operator ugly:
1 2 3 4 5 | foo = bar; if (foo == null) { foo = baz; } |
Also discovered recently: extension methods. Not having private access is a bit of a drawback, though I can certainly understand why that is. It amounts to a convenient way to write helper code for awkward APIs.
