Hey I was writing some timer functions (like JS setTimeout) and when invoking endFunc I checked:

if(endFunc!= null) endFunc();

and VS2017 proposed endFunc?.Invoke(). I suppose, there is no difference, but what exactly does ?. means there? Can I use it in other cases like myString?.SubString()?

"Can I use it in other cases like myString?.SubString()?" Why not try it out? – MakePeaceGreatAgain Apr 24 '19 at 06:48

it is [null-conditional operator](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/null-conditional-operators) (so called `Elvis operator`) – vasily.sib Apr 24 '19 at 06:51
