如何计算C＃中没有空格的单词？ [英] How to count words without space in C# ?

问题描述

亲爱的先生，



我想在一个句子中计算没有空格的单词，但是我遇到的问题是，当我运行程序空间时，也会计算单词但是我只想算数字请指导。我的C＃程序如下。

Dear Sir,

I want to count words without space in a Sentence but I face a problem that when I run the program space is also count with words but I want count only words Please guide . My C# program is as under.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Text.RegularExpressions;
using System.IO;

namespace Static_Method_Count_Word
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Please Enter Any Paragraph .");
            string Paragraph = Console.ReadLine();
            Count.Coun(Paragraph);
            Console.ReadLine();
        }
    }
    class Count
    {
        public static void Coun(string Paragraph )
        {
            int i = 0,b=0;
            int Count2 = 1;
            for (i = 0; i < Paragraph.Length; i++)
            {
                if (Paragraph[i] == ' ')
                {
                    for (b = i; b < Paragraph.Length; b++)
                    {
                        if (Paragraph[b] != ' ' && Paragraph[b] != '\t')
                        {
                            Count2++;
                            break;
                        }
                    }
                }
	     }
	}
     }
}

推荐答案

两件事：

1）使用相应的拆分选项不将空白部分放入列表中

2）允许拆分功能取 char.IsWhitespace（c）作为分隔符

请参阅 null 参数中的备注 String.Split方法（Char []，StringSplitOptions） [< a href =https://msdn.microsoft.com/en-us/library/ms131448(v=vs.110).aspx\"target =_ blanktitle =New Window> ^ ]。

Two things:
1) use the respective split option to not place the empty parts into the list
2) allow the split function to take char.IsWhitespace(c) as separator
See remarks on null parameter in String.Split Method (Char[], StringSplitOptions)[^].

char[] takeWhiteSpaceSeparators = null;
int wordCount = paragraph.Split( takeWhiteSpaceSeparators
                               , StringSplitOptions.RemoveEmptyEntries
                               )
                               .Length;

干杯

您可以尝试使用此代码来计算单词，

You can try using this code for counting the words,

// Method returns an integer and gets a string paragraph
int GetWords(string paragraph) {
// It returns the total number of words
return (
        // Splits the paragraph at every occurance of empty string
        paragraph.Split(new string[] {" "}, 
        // Spliting options let you omit the empty words, like " "
        StringSplitOptions.RemoveEmptyEntries).Length
       );
}

这将返回段落中的单词总数或字符串的总数。要测试这个程序逻辑，你可以使用这个小提琴： https://dotnetfiddle.net/E1JIy2 [ ^ ]。有关此Split方法签名和其他详细信息的更多信息，请参阅此MSDN文档 [ ^ ]。

This would return the total number of words in the paragraph or what so ever the string is. To test this program logic, you can use this fiddle: https://dotnetfiddle.net/E1JIy2[^]. For more on this Split method signature and other details, see this MSDN document[^].

使用字符串拆分方法，更准确地说，这个重载版本可能是最好的：见这里 [ ^ ]



您需要：

Use the string split method and more accurately this overloaded version is probably the best: see here[^]

You´ll need:

string [] seperator = { " " };
string [] words = Paragraph.Split(seperator, StringSplitOptions.RemoveEmptyEntries);
int nrofwords = words.Length;

希望这会有所帮助。

hope this helps.
