如何将输入重定向为ReadLine和WriteLine的输出？ （菜鸟）

Question

我正在尝试创建一个小游戏，但我希望用户输入他的名字，这样游戏就更加真实了！怎么样？？？？ 我试图这样做，如果你输入3（案例3）应用程序刚关闭！ 这是代码！

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

namespace Game
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Does anyone copy?");
           // Thread.Sleep(3000);
            Console.WriteLine("Is there anybody listening?");
           // Thread.Sleep(3000);
            Console.WriteLine("Please i need help!!!");
            //Thread.Sleep(3000);
            Console.WriteLine("1. Who is this?");
            Console.WriteLine("2. Yes i copy!");
            Console.WriteLine("3. Ignore the message!");
            String choice = Console.ReadLine();
            switch (choice)
            {
                case "1":
                    //Thread.Sleep(2000);
                    Console.WriteLine("I'm Emma!");
                    //Thread.Sleep(6000);
                    Console.WriteLine("Oh my God i tought nobody was going to answer!");
                    //Thread.Sleep(2000);
                    Console.WriteLine("Who are you?");
                    break;
                case "2":
                    //Thread.Sleep(6000);
                    Console.WriteLine("Oh my God i tought nobody was going to answer!");
                    //Thread.Sleep(2000);
                    Console.WriteLine("I'm Emma by the way!");
                    //Thread.Sleep(2000);
                    Console.WriteLine("Who are you?");
                    break;
                case "3":

                break;
            }

        Console.ReadLine();
        string yourName;
        yourName = Console.ReadLine();
        //Thread.Sleep(10000);
        Console.WriteLine("Hey {0}... Sorry i got you so worried... i was just scared someone was in my room!" yourName );
        //Thread.Sleep(20000);



    }
}

}

Answer 1

在您的代码中，您尝试使用string.Format，正确的语法是：

string yourName;
yourName = Console.ReadLine();
//Thread.Sleep(10000);
Console.WriteLine(String.Format("Hey {0}... Sorry i got you so worried... i was just scared someone was in my room!", yourName));
//Thread.Sleep(20000);

您缺少的重要部分是Console.WriteLine(String.Format(

您还需要使用逗号分隔变量和文本，因为它们是String.Format()方法中的不同参数。

除此之外，你还可以像这样使用字符串插值

Console.WriteLine($"Hey {yourName}... Sorry i got you so worried... i was just scared someone was in my room!");

这与String.Format的工作方式类似，但通过在字符串前添加$来使用它。

正如您所看到的，这样做的好处是，变量名称位于大括号内{yourName}，而不是放置0.这比写入的代码少String.Format
