在c#中将用户输入转换为命令行

using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("请输入命令行:");
        string userInput = Console.ReadLine();

        // 解析命令行
        string[] commandParts = userInput.Split(' ');
        string command = commandParts[0];
        string[] arguments = new string[commandParts.Length - 1];
        Array.Copy(commandParts, 1, arguments, 0, arguments.Length);

        // 根据命令执行相应操作
        switch (command)
        {
            case "hello":
                Console.WriteLine("你好！");
                break;
            case "add":
                if (arguments.Length == 2)
                {
                    int num1 = int.Parse(arguments[0]);
                    int num2 = int.Parse(arguments[1]);
                    int sum = num1 + num2;
                    Console.WriteLine("结果为：" + sum);
                }
                else
                {
                    Console.WriteLine("参数错误！");
                }
                break;
            default:
                Console.WriteLine("未知命令！");
                break;
        }
    }
}
