查找单词的正则表达式 [英] Regular expression for finding a word

问题描述

我有一个很长的字符串作为输入，我想计算该字符串中的单词数.

I have a long string of characters as input and I want to count the number of words in that string. How can I do it through regular expression?

推荐答案

Try:

Try:

Regex word = new Regex(@"\w+");
string data = "The quick brown fox jumps over the lazy dog.";
Console.WriteLine(word.Matches(data).Count);

获取 Expresso [ ^ ]-它是免费的，它检查并生成正则表达式.

Get a copy of Expresso [^] - it''s free, and it examines and generates Regular expressions.

string Input;
Input=Console.ReadLine();
string[] Output=Input.Split(' ');
Console.WriteLine("No of Words in Given String is {0}",Output.Length.ToString());
