用户会输入一个字母，它将检查该字母是否包含在变量listWords中，我认为我过度思考这个并且这是一个简单的解决方案，但我不能为我的生活思考如何实现这一点。

这是一个奇怪的请求。给定一个Windows窗体上的按钮，下面是代码来做你想要的。只需更换＆＃34; a＆＃34;用你的实际输入。

考虑将随机单词生成和角色的实际测试分成两个单独的部分。

祝你好运

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim randomWord As String = GetRandomWord()
        Dim userInput As Char = "a"
        If randomWord.Contains(userInput) Then
            MessageBox.Show("Yes, the word '" + randomWord + "' DOES contain the letter '" + userInput + "'")
        Else
            MessageBox.Show("No, the word '" + randomWord + "' DOES NOT contain the letter '" + userInput + "'")
        End If
    End Sub

    Private Function GetRandomWord() As String
        Dim listWords(4) As String
        listWords(0) = "juicy"
        listWords(1) = "aaron"
        listWords(2) = "power"
        listWords(3) = "weigh"
        listWords(4) = "public"
        Dim Index As Integer = GetRandomNumber(listWords.Length - 1)
        Return listWords(Index)
    End Function

    Private Function GetRandomNumber(maxValue As Integer) As Integer
        'Math.Ceiling rounds up to the nearest whole number
        Return Math.Ceiling(Rnd() * maxValue)
    End Function
End Class

如果用户输入包含随机变量listWords中的字符
