我正在尝试根据位于此处的控制台机器人的代码创建一个 Chatter Bot

输入输入后运行程序时出现异常：“未处理格式异常”“输入字符串的格式不正确。” 在“爱丽丝”课程中：

Result result = myBot.Chat(request);

似乎请求返回 null。有人可以帮我弄清楚为什么在 AIML 文件中找不到我的输入和/或为什么它返回 null 吗？

下面是主类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using AIMLbot;

namespace Chatbot
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        String userInput = null;
        alice myAlice = new alice();
        public MainWindow()
        {
            InitializeComponent();
        }

        private void inputButtonClick(object sender, RoutedEventArgs e)
        {
            userInput = inputTextBox.Text;
            outPutTextBlock.Text = myAlice.getOutput(userInput);
            inputTextBox.Text = "";
            userInput = null;
        }
    } 
}

下面是“爱丽丝”类代码：

//Written by Matt Gonzalez
//with help from Nicholas H.Tollervey's ConsoleBot2.5
//and AIML base files from the A.L.I.C.E Bot project

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using AIMLbot;

namespace Chatbot
{
    class alice
    {
        private Bot myBot;
        private User myUser;

        /// <summary> 
        /// Create a new instance of the ALICE object 
        /// </summary>

        public alice()
        {
            myBot = new Bot();
            myUser = new User("consoleUser", myBot);
        }

        /// <summary> 
        /// This initialization can be put in the alice() method 
        /// but I kept it seperate due to the nature of my program. 
        /// This method loads all the AIML files located in the \AIML folder 
        /// </summary>

        public void Initialize()
        {
            myBot.loadSettings();
            myBot.isAcceptingUserInput = false;
            myBot.loadAIMLFromFiles();
            myBot.isAcceptingUserInput = true;
        }

        /// <summary> 
        /// This method takes an input string, then finds a response using the the AIMLbot
        /// library and returns it 
        /// </summary> 
        /// <param name="input">Input Text</param> 
        /// <returns>Response</returns>

        public String getOutput(String input)
        {
            Request request = new Request(input, myUser, myBot);
            Result result = myBot.Chat(request);
            return (result.Output);
        }
    }

}

您好，我已经根据提供的代码运行了您的程序。您的问题与 wpf 无关。这是关注 alice.Initialize() 方法。它根本没有被调用。如果您在“getOutput”之前调用它一切正常。出于测试目的，我已将其放入 alice ctor 中。

    public alice()
    {
        myBot = new Bot();
        myUser = new User("consoleUser", myBot);
        Initialize();
    }
