我在计数时遇到问题ToString();我试图让程序在每次用户说出其中一种动物的名字后添加一个数字，例如 1、2 然后 3，从而在计数显示（记分板）上添加一个数字，这将是显示在lblCount标签内供用户查看

目前我什么都有这个

我不确定我是否完全理解您的问题，但我确实看到了一个相当明显的错误：

        foreach (RecognizedWordUnit word in e.Result.Words)
        {
            int count = 0;
            count += 1;

每次循环都会将计数重置为 0，然后立即将其加 1，因此您的标签将始终显示为 1。

只需将初始化程序移出循环即可。

        int count = 0;
        foreach (RecognizedWordUnit word in e.Result.Words)
        {
            count += 1;

如果您想显示程序生命周期内的总计数，则需要将计数变量移动为表单的成员。像这样：

public partial class Form1 : Form
{  
     private int count = 0;
     // ...
}

然后将您的事件处理程序更改为：

void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {

        foreach (RecognizedWordUnit word in e.Result.Words)
        {
            count += 1;
