如何在c#内部的类中声明一个变量

本文关键字：变量 一个 声明 内部 | 更新日期: 2023-09-27 18:14:39

我想声明以下内容:

            var simlBot = new SimlBot();
            var botUser = simlBot.CreateUser();
            var packageString = File.ReadAllText("SIMLPackage.simlpk");
            simlBot.PackageManager.LoadFromString(packageString);

如果我直接在类中声明它，我得到:"上下文关键字'var'可能只出现在局部变量声明中或脚本代码中"

我不能在if语句中声明它，因为我不能从外部访问它。

        if (hasBotBeenCreated == false)
        {
            var simlBot = new SimlBot();
            var botUser = simlBot.CreateUser();
            var packageString = File.ReadAllText("SIMLPackage.simlpk");
            simlBot.PackageManager.LoadFromString(packageString);
        }

我需要在函数中使用以下形式:

        var chatRequest = new ChatRequest(textReceived, botUser);
        var chatResult = simlBot.Chat(chatRequest);

我能做什么?问题是最后一段代码不能访问botUser和simlBot。我现在让它工作的方式是每次调用函数时重新创建对象，但这需要花费很多时间。

完整的代码是

public partial class Form1 : Form
{
    string textEntered = "";
    string response = "";
    SpeechSynthesizer synth = new SpeechSynthesizer();
    bool hasBotBeenCreated = false;
    public Form1()
    {
        InitializeComponent();
    }
    private void button1_Click(object sender, EventArgs e)
    {
        textEntered = textBox1.Text;
        textBox1.Text = "";
        if (textEntered != "")
        {
            sendToAI(textEntered);
        }
    }
    void sendToAI(string textReceived)
    {
        listBox1.Items.Add(textEntered);
        response = getResponse(textEntered);
        listBox1.Items.Add(response);
        synth.Speak(response);
    }
    string getResponse(string textReceived)
    {
        if (hasBotBeenCreated == false)
        {
            var simlBot = new SimlBot();
            var botUser = simlBot.CreateUser();
            var packageString = File.ReadAllText("SIMLPackage.simlpk");
            simlBot.PackageManager.LoadFromString(packageString);
        }
        var chatRequest = new ChatRequest(textReceived, botUser);//These two can't access the objects created above
        var chatResult = simlBot.Chat(chatRequest);
        if (chatResult.Success)
        {
            var botMessage = chatResult.BotMessage;
            return botMessage;
        }
        else
        {
            return "I don't have a response for that";
        }
    }
}

    string getResponse(string textReceived)
    {
        SimlBot simlBot;
        BotUser botUser;
        if (hasBotBeenCreated == false)
        {
            simlBot = new SimlBot();
            botUser = simlBot.CreateUser();
            var packageString = File.ReadAllText("SIMLPackage.simlpk");
            simlBot.PackageManager.LoadFromString(packageString);
        }
        var chatRequest = new ChatRequest(textReceived, botUser); //These get the error
        var chatResult = simlBot.Chat(chatRequest);
        if (chatResult.Success)
        {
            var botMessage = chatResult.BotMessage;
            return botMessage;
        }
        else
        {
            return "I don't have a response for that";
        }
    }

如何在c#内部的类中声明一个变量

添加成员:

 SimlBot simlBot;
 WhatEverTypeOfCreateUserIs botUser;

然后初始化它们:

    if (hasBotBeenCreated == false)
    {
        simlBot = new SimlBot();
        botUser = simlBot.CreateUser();
       ....
    }

public partial class Form1 : Form
{
    string textEntered = "";
    string response = "";
    SpeechSynthesizer synth = new SpeechSynthesizer();
    bool hasBotBeenCreated = false;
    SimlBot simlBot;
    BotUser botUser;
    public Form1()
    {
        InitializeComponent();
    }
    private void button1_Click(object sender, EventArgs e)
    {
        textEntered = textBox1.Text;
        textBox1.Text = "";
        if (textEntered != "")
        {
            sendToAI(textEntered);
        }
    }
    void sendToAI(string textReceived)
    {
        listBox1.Items.Add(textEntered);
        response = getResponse(textEntered);
        listBox1.Items.Add(response);
        synth.Speak(response);
    }
    string getResponse(string textReceived)
    {
        if (hasBotBeenCreated == false)
        {
            simlBot = new SimlBot();
            botUser = simlBot.CreateUser();
            var packageString = File.ReadAllText("SIMLPackage.simlpk");
            simlBot.PackageManager.LoadFromString(packageString);
        }
        var chatRequest = new ChatRequest(textReceived, botUser);//These two can't access the objects created above
        var chatResult = simlBot.Chat(chatRequest);
        if (chatResult.Success)
        {
            var botMessage = chatResult.BotMessage;
            return botMessage;
        }
        else

        }
