字符串操作在文本框中对单词进行计数 [英] String Manipulation Counting Words in a textbox

问题描述

下面是我对一个句子中的元音进行计数的方法，如何得到它来对句子中的单词数进行计数?获得总字数后，我需要一个消息框来显示字数，然后反转句子并将其倒退到文本框中.

Below is what I have for counting vowels in a sentence how do I get it to count the number of words in the sentence? After I get the total word count I need a message box to show the count then reverse the sentence and put it in backwards into the text box.

<pre lang="vb">Public Function CountVowels(ByVal strSentence As String, ByRef intVowels As Integer) As Integer<br />
        Dim intIndex As Integer<br />
        Dim strCurrentLetter As String<br />
        strSentence.ToLower()<br />
<br />
        For intIndex = 0 To strSentence.Length - 1<br />
            strCurrentLetter = strSentence.Substring(intIndex, 1)<br />
            If strCurrentLetter = "a" Or strCurrentLetter = "e" Or strCurrentLetter = "i" Or strCurrentLetter = "o" Or strCurrentLetter = "u" Then<br />
                intVowels += 1<br />
            End If<br />
        Next<br />
        Return intVowels<br />
    End Function</pre><br />

推荐答案

最简单的方法是使用string.Split:

The easiest way is to use string.Split:

Dim text As String = "the quick, brown fox,jumps over the lazy dog"
Dim words As String() = text.Split(New Char() {" "C, ","C, "."C, "?"C, "!"C}, StringSplitOptions.RemoveEmptyEntries)
Dim i As Integer = words.Length

然后，您可以将其作为句子向后重建，并将其显示在MessageBox中.我不会给您该代码:您应该做一些自己的作业！ :laugh:

You can then rebuild the parts backwards as a sentence and display that in a MessageBox. I won''t give you that code: You should do some of your own homework! :laugh:
