如何在语音识别程序中添加添加数组，请参见下面的代码？我试过了使用streamRead读取一个字符串并创建一个数组并放在commands.Add(new String[]之后，请参阅下面的代码，但无法实现。

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.Speech.Recognition;
using System.Speech.Synthesis;
using System.Collections.Generic;
using System.Data;
using System.Text;
using System.Globalization;
using System.IO;

    //Speech to Text 
       amespace CSharp_Speech_ConsoleApp

        {
        class Program
        {

         [DllImport("winmm.dll")]

         public static extern int waveInGetNumDevs();

         SpeechRecognitionEngine recognizer = new 
         SpeechRecognitionEngine(new      
         System.Globalization.CultureInfo("en-US"));   

         static void Main(string[] args)
         {
         // Make a Keywords array
         Choices commands = new Choices(); 
         //How to make this array  by importing strings from a file ? 
         commands.Add(new String[] { "Good morning.","Hello Mike.",
         "Good morning Eddy.","Good afternoon.","Good Evening","Hello",          
         "How are you", "Listen to me Mike", "Stop listening Mike!"
        });

             GrammarBuilder gBuilder = new GrammarBuilder();

             gBuilder.Append(commands);
             Grammar grammar = new Grammar(gBuilder);

             recogEngine.LoadGrammar(grammar);


         //get total number of sound input devices

          int waveInDevicesCount = waveInGetNumDevs(); 

          if(waveInDevicesCount == 0)
        {
            Console.WriteLine("No microphone detected.!");    

        }

        else

    {
            Console.WriteLine("Microphone detected. "); 

            recogEngine.SetInputToDefaultAudioDevice();

            recogEngine.SpeechRecognized += recogEngine_SpeechRecognized;

            recogEngine.RecognizeAsync(RecognizeMode.Multiple);

    }    

        Console.ReadLine();
       }
     // Console Display Speech Recognized result Text 
       static void recogEngine_SpeechRecognized(object sender,  
       SpeechRecognizedEventArgs e) 
    {

         string managedString = e.Result.Text;

         char[] st = managedString.ToCharArray();

         Console.WriteLine(st);

       }

      }

    }

如何通过从文件导入字符串来创建数组？

这将为您提供文件中的所有行：

var lines = File.ReadAllLines(@"PathToYourFile");

以上内容将文件中的所有行都读入内存。还有另一种方法可以在需要时逐个读取这些行：

var lines = File.ReadLines(@"PathToYourFile");

这个返回IEnumerable<string>。例如，假设您的文件有1000行，ReadAllLines将所有1000行读入内存。但ReadLines会在需要时逐一读取它们。因此，如果您这样做：

var lines = File.ReadLines(@"PathToYourFile");
var line1 = lines.First();
var lastLine = lines.Last();

即使您的文件有1000行，它也只会将第一行和最后一行读入内存。

那么何时使用ReadLines方法？

让我们说你需要读一个有1000行的文件，而你感兴趣的只有900到920行，那么你可以这样做：

var lines = File.ReadLines(@"PathToYourFile");
var line900To920 = lines.Skip(899).Take(21);
