Getting a default value from a nullable

suggest change

The .GetValueOrDefault() method returns a value even if the .HasValue property is false (unlike the Value property, which throws an exception).

class Program
{
    static void Main()
    {
        int? nullableExample = null;
        int result = nullableExample.GetValueOrDefault();
        Console.WriteLine(result); // will output the default value for int - 0
        int secondResult = nullableExample.GetValueOrDefault(1);
        Console.WriteLine(secondResult) // will output our specified default - 1
        int thirdResult = nullableExample ?? 1;
        Console.WriteLine(secondResult) // same as the GetValueOrDefault but a bit shorter
    }
}

Output:

0
1
