请问这段代码的输出结果，and why？

 class Person
    {
        private int age;
        public int Age 
        {
            get { return age; }
            set { age = value; }
        }

    }
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(GetPerson().Age);
            Console.ReadKey();
        }
        static Person GetPerson()
        {
            Person p = new Person();
            p.Age = 8;
            try
            {
                p.Age++;
                Console.WriteLine("a");
                return p;

            }
            finally
            {
                Console.WriteLine("b");
                p.Age++;
            }

        }
    }

ab10,,,,,是吗？

try{
}catch{}
finally的使用

理解finally，不管是否catch到异常，它都会被执行
