C# 一句话多个答案

Question

我想编写一个程序来执行以下操作。

用户提出一个问题，程序对该问题有 5 个不同的答案，程序需要随机选择一个答案。
该程序使用语音命令，程序的反馈是语音的。

代码

public partial class Form1 : Form
{           

    SpeechSynthesizer s = new SpeechSynthesizer();
    Choices list = new Choices();
    Boolean wake = true;
    public Form1()
    {

        SpeechRecognitionEngine rec = new SpeechRecognitionEngine();
        list.Add(new String[] { "hello", "how are you", "what time is it", "what day is it","wake", "sleep", "restart", "open studio", "close studio", "search ", "standby", "mute", "unmute", "up", "down", "hex system up", "google dog"});
        Grammar gr = new Grammar(new GrammarBuilder(list));
        try
        {

            rec.RequestRecognizerUpdate();
            rec.LoadGrammar(gr);

    public int r { get; set; }

    public int rnd { get; set; }

    public Grammar dictationGrammar { get; set; }

Answer 1

您需要 System.Random to generate a random number 从 x 到 y（0..4、1..5 随便）：

using System;

public class Program
{
    public static void Main()
    {
        // Define answers
        string[] answers = new[] {
            "Some answer",
            "Another answer",
            "Yet another answer",
            "Foo answer",
            "Bar answer"
        };

        // Create a new instance of the Random class
        var rng = new Random();

        // Pick a random number between 0 and the number of elements in the answers array
        int randomnumber = rng.Next(0, answers.Length);

        // Print random answer
        Console.WriteLine(answers[randomnumber]);
    }
}

就是这样。就那么简单。玩上面的代码 here.

在你的情况下你可能不会写 Console.WriteLine(answers[randomnumber]); 但 say(answers[randomnumber]);

另一个注意事项：而不是：

if (r == "hex system up") { ... }
if (r == "down") { ... }
if (r == "up")  { ... }
if (r == "unmute") { ... }
if (r == "mute")  { ... }
if (r == "standby") { ... }

学习 switch statement 并重写您的代码，使其看起来类似于：

switch (r.ToLowerInvariant()) {
    case "hex system up":
        Process.Start(@"C:\Program Files\Rainmeter\Rainmeter.exe");
        Say("Welcome back sir");
        break;
    case "down":
        ExecuteCommand(@"C:\nircmd.exe changesysvolume -10000");
        break;
    case "up":
        ExecuteCommand(@"C:\nircmd.exe changesysvolume 10000");
        break;
    case "unmute":
        ExecuteCommand(@"C:\nircmd.exe mutesysvolume 0");
        Say("system unmute sir");
        break;
    case "mute":
        Say("mute now!");
        ExecuteCommand(@"C:\nircmd.exe mutesysvolume 1");
        break;
    case "standby":
        Say("The system will enter in waiting mode sir");
        ExecuteCommand(@"C:\nircmd.exe standby");
        break;
    // ... rest here ...
    default:
        Say("Unknown command sir!");
        break;
}

此外，尽量保持一致：

ExecuteC命令 -> say => S天。
@"C:\Progam Files..." -> "C:/nircmd.exe" => @"C:\nircmd.exe"
