How can I set the output of Int32.TryParse to a null if it cannot parse a string? [duplicate]

Question

I have a variable

int? a = Int32.TryParse(b);

How can I make it that a becomes a null if b is found not to be an integer?

This should work for you

        int? a = int.TryParse(b, out var value) ? value : (int?) null;

you should use var instead of int?

        var a = int.TryParse(b, out var value) ? value : (int?) null;
