最後一條語句不會運行c＃！

Question

請幫忙！我運行這個程序並輸入了所有3個輸入，但是最後一個輸入程序代碼不會運行，並且程序剛剛退出！我不知道，因爲我完全按照這本書！

 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); 

Answer 1

的代碼添加結束：

Console.ReadLine();
