在用户输入“Q”，“q”，“退出”或“退出”以终止它之前，如何运行控制台应用程序？

在用户输入“Q”，“q”，“退出”或“退出”以终止它之前，如何运行控制台应用程序？

这是我目前的代码：

public class Class1 { [STAThread] static void Main(string[] args) { string userName; int i = 0, totalCal = 0, cal = 1; Console.WriteLine("Welcome to the magical calorie counter!"); Console.WriteLine(); Console.Write("Enter in your name -> "); userName = Console.ReadLine(); for (i = 0; i <= 10; i++) { Console.WriteLine("Hello {0}.....Let's add some calories!!", userName); }// end for loop Console.WriteLine(); while (cal != 0) { Console.Write("Enter some Calories:: "); cal = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("You entered {0}", cal); Console.WriteLine(); totalCal += cal; Console.WriteLine(); Console.WriteLine("-------------------So far you have a total of {0}------------------", totalCal); Console.WriteLine(); Console.WriteLine(); }// end of while }// end of amin }//end of class

假设您的程序中没有任何其他错误…只需添加如下几行：

 using System; class Class1 { [STAThread] static void Main(string[] args) { string userName; string line; int i = 0, totalCal = 0, cal = 1; Console.WriteLine("Welcome to the magical calorie counter!"); Console.WriteLine(); Console.Write("Enter in your name -> "); userName = Console.ReadLine(); for (i = 0; i <= 10; i++) { Console.WriteLine("Hello {0}.....Let's add some calories!!", userName); }// end for loop Console.WriteLine(); while (true) { Console.Write("Enter some Calories:: "); line = Console.ReadLine().ToLower(); if (line == "q" || line == "quit") { break; } else if (!int.TryParse(line, cal)) { Console.WriteLine("Not a valid option. Please try again."); continue; } Console.WriteLine("You entered {0}", cal); Console.WriteLine(); totalCal += cal; Console.WriteLine(); Console.WriteLine("-------------------So far you have a total of {0}------------------", totalCal); Console.WriteLine(); Console.WriteLine(); }// end of while }// end of amin }

我认为退出，或退出是好的。 或者你可以接受e或q。

我更喜欢精通键盘的用户可能已经知道的键盘快捷键，例如Ctrl + W，这是在现代Web浏览器上关闭标签的默认键。
