C# Null-Conditional Operator (? Operator) Explained!

Показать описание

To make your C# code more readable, the null-conditional operator has been introduced in C# version 6. With this operator you can simply type a question mark after an object reference to check it for null. In this video I will show you what it does and how to use it.

I came here to resolve a question and I left with another. I did not know that it was possible to define an object of the same class within the definition of the class itself. Either way, thanks for resolving my concerns about Null-conditional operators

I often use combo of operators ?. and ?? . It`s useful if need to react on null like ?? "A person has no name");

Does it make sense to declare properties with the ? operator? For example, public class foo{ public string bar? {get; set; } }. If so - how do you assign to bar?
