问题描述

Public Sub word()
            Dim l, i, number As Integer
            no = 0
            Console.WriteLine("Type the text")
            s = Console.ReadLine()
            l = Len(s)
            Do While (i < l)
                If s(i) = "" Then
                    no = no + 1

                End If
                i = i + 1
                number = no
            Loop

            Console.WriteLine("The no of words is {0}", number)
        End Sub
    End Class

我尝试过：



i已经尝试了很多次。比如说没有单词是0.

What I have tried:

推荐答案

使用拆分（）： http://www.dotnetperls.com/split-vbnet [ ^ ]

你应该试试：

You should try:

If s(i) = " " Then

a空格被加入之间



否则，您可以简化代码：

a space was added between quotes

Otherwise, you can simplify your code:

    Public Sub word()
        Dim l, i , number As Integer
        no = 0
        Console.WriteLine("Type the text")
        s = Console.ReadLine()
        l = Len(s)
        Do While (i < l)
            If s(i) = " " Then
                no = no + 1

            End If
            i = i + 1
            number = no
        Loop

        Console.WriteLine("The no of words is {0}", number no)
    End Sub
End Class

请先阅读我对该问题的评论。正如我在那里提到的，它取决于你定义的单词。
