C# has a nice ?? operator that can be chained.
In a statement, it will return the first non-null value or null if none are found to not be null.
For example, if you had the code:
string? value1 = null;
string? value2 = nameof(value2);
string? result = value1 != null ? value1 : value2;
The last line could be simplified down to:
string result = value1 ?? value2;
As far as I know, there is no limit on how many ?? can be chained!
