Question

好吧，我有问题。我的代码打印出文本，提供了输入三种内容的选项。如果您键入其中一个，它会写一行。但无论出于什么原因，它只是在打印出文本后立即关闭（在visual studio中我会使用Ctrl + f5），但因为我试图从.exe启动而无法做到这一点。在打印结果后，如何使窗口保持打开而不关闭。

我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    /// <summary>
    /// This console application was written by Graham Long.
    /// 
    /// This is a series of basic programming items that I am using to help myself learn c#
    /// </summary>
    class Program
    {
        //Below is a function
        static void Main(string[] args)
        {
            //All of the code starts here. Some call this an 'entry point'.

            String myString = "Hello world! My name is Graham and I am the developer of this application.";
            Console.WriteLine(myString);
            Console.WriteLine(" ");
            Console.WriteLine("Type 'q' for an explanation of some British slang.");
            Console.WriteLine("Type 'w' for some meta text.");
            Console.WriteLine("Type 'e' for the same compliment printed twice.");

            ConsoleKeyInfo keyInfo = Console.ReadKey();
            if(keyInfo.KeyChar == 'q')
            {
                Console.WriteLine("'Chav' is British slang for 'Council House And Violent', council house meaning a house on rent from the council (They're cheap, which means they're usually associated with poorness) and violent meaning easily angered and vicious.");
            }
            else if(keyInfo.KeyChar == 'w')
            {
                printSomeTextToScreen();
            }
            else if(keyInfo.KeyChar == 'e')
            {
                printNiceTextToScreenTwice();
            }

            //Console.WriteLine("Did you type {0}?", keyInfo.KeyChar.ToString());

        }
        static void printSomeTextToScreen()
        {
            //Using a separate function from 'Main' ('Main' is the main function).
            String someText = "This is some text being printed from a different function.";
            Console.WriteLine(someText);
        }
        static void printNiceTextToScreenTwice()
        {
            //Using another separate function from 'Main', this function includes a 'for' loop which is a piece of code that runs until a condition is met.
            String niceText = "You have a lovely fore arm.";
            for (uint counter = 0; counter < 2; counter++)
            {
                Console.WriteLine(niceText);
            }
        }
    }
}

抱歉提前格式错误（以防万一）。

Answer 1

如果您没有告诉应用程序执行任何操作，那么它就会完成。例如，您可以在Main()方法的末尾添加此行：

Console.ReadKey();

这告诉程序要等到另一个键被击中。

Answer 2

使用while循环，根据输入的某些键，您可以退出循环。

   static void Main(string[] args)
    {
        //All of the code starts here. Some call this an 'entry point'.           
        do
        {
            String myString = "Hello world! My name is Graham and I am the developer of this application.";
            Console.WriteLine(myString);
            Console.WriteLine(" ");
            Console.WriteLine("Type 'q' for an explanation of some British slang.");
            Console.WriteLine("Type 'w' for some meta text.");
            Console.WriteLine("Type 'e' for the same compliment printed twice.");
            Console.WriteLine("Type 's' to close.");

            ConsoleKeyInfo keyInfo = Console.ReadKey();
            if (keyInfo.KeyChar == 'q')
            {
                Console.WriteLine("'Chav' is British slang for 'Council House And Violent', council house meaning a house on rent from the council (They're cheap, which means they're usually associated with poorness) and violent meaning easily angered and vicious.");
            }
            else if (keyInfo.KeyChar == 'w')
            {
                printSomeTextToScreen();
            }
            else if (keyInfo.KeyChar == 'e')
            {
                printNiceTextToScreenTwice();
            }
            else if (keyInfo.KeyChar == 's')
            {
                break;
            }
        }
        while (true);
    }

如何使我的C＃控制台程序不立即关闭？
