Tae*_*on. 0 c# string loops count cpu-word
我想计算字符串中的单词数。就像如果给定一个字符串:
string str = "Hello! How are you?";

那么输出将是:
Number of words in string “Hello! How are you?” is 4.

我正在使用 for 循环,这些是我当前的代码。
string wordCountStr = "";
int noOfWords = 0;
private void btn_Computate4_Click(object sender, EventArgs e)
{
wordCountStr = tb_Qns4Input.Text.ToString(); //tb_Qns4Input is a textbox.
for (int i = 0; i< wordCountStr.Length; i++)
{
//I don't know how to code here.
}
lbl_ResultQns4.Text = "Number of words in string " + wordCountStr + " is " + noOfWords;
}

哦,是的,我正在使用 Microsoft Visual Studio 2013 进行工作。所以代码在按钮点击事件下。
另外:使用“foreach”、“for 循环”、“do/while”循环和“while”循环进行编码有哪些不同的方法?我只能将这 4 个循环用于我的工作。
我已经通过使用这些代码解决了这个问题:
string wordCountStr = "";
int noOfWords = 0;
private void btn_Computate4_Click(object sender, EventArgs e)
{
wordCountStr = tb_Qns4Input.Text.ToString();
foreach (string sentence in wordCountStr.TrimEnd('.').Split('.'))
{
noOfWords = sentence.Trim().Split(' ').Count();
}
lbl_ResultQns4.Text = "Number of words in ''" + wordCountStr + "'' is " + noOfWords;
}

假设完美的输入,您可以简单地分割空间,然后获得Length结果数组的 。
int count = wordCountStr.Split(' ').Length;
