There are a couple! The ternary operator: testvar2 = testVar1 != null ? testvar1 : testvar2; Would be exactly the same logic. Or, as commented you can use the null coalescing operator: testVar2 = testVar1 ?? testVar2 (although now that’s been commented as well) Or a third option: Write a method once and use it … Read more
Using null-coalescing operator ( ?? ): get { _rows = _rows ?? new List<Row>(); return _rows; } OR (less readable): get { return _rows ?? (_rows = new List<Row>()); } The ?? operator is called the null-coalescing operator. It returns the left-hand operand if the operand is not null; otherwise it returns the right hand … Read more
This is a null coalescing operator. The method above states x is assigned y’s value, unless y is null, in which case it is assigned z’s value.
Step by step explanation: params Delegate?[] delegates – It is an array of nullable Delegate params Delegate?[]? delegates – The entire array can be nullable Since each parameter is of the type Delegate? and you return an index of the Delegate?[]? array, then it makes sense that the return type is Delegate? otherwise the compiler … Read more

The JavaScript equivalent of the C# null coalescing operator (??) is using a logical OR (||): var whatIWant = … Read more
