最后一句话不会运行c＃！

Question

请帮忙！我运行了这个程序并输入了所有3个输入，但是最后一个编写的代码不会运行，程序就会退出！我不知道，因为我完全按照这本书！

        string userName = "";
        int userAge = 0;
        int currentYear = 0;

        Console.Write("Please enter your name: ");
        userName = Console.ReadLine();
        Console.Write("Please enter your age: ");
        userAge = Convert.ToInt32(Console.ReadLine());
        Console.Write("Please enter the current year: ");
        currentYear = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("Hello World! My name is {0} and I am {1} years old. I was born in {2}.", userName, userAge, currentYear - userAge);

在代码末尾添加：

Console.ReadLine();
