如何找到字符串 C# 的第 n 个单词？

Question

I am trying find the nth word of a string. How do I do that using C#? I have tried splitting in spaces after that I don't know how to check each word.

Answer 1

You can check for spaces in the string and split. and string array from those segments. After that pass index to get the array item. You can find the explanation here. Question number 12. http://xcelitsolutions.co.uk/JustCode/CSharp/AllQuestions.php?Chapter=Strings

Console.WriteLine("Enter the String");
string text = Console.ReadLine();//Enter the string
Console.WriteLine("Enter which word to show");//location of the word
int number = Convert.ToInt32(Console.ReadLine());
char[] mychar = {' '};
string[] wordslist = text.Split(mychar);
Console.WriteLine(wordslist[number-1]);

Answer 2

After you use the split() function an array is returned with number of elements = number of words that the string has been split into. The split occurs in the same order. Simply call the index of the word you want.

string phrase = "The quick brown    fox     jumps over the lazy dog.";
string[] words = phrase.Split(' ');
Console.Writeline(words[5]); // prints 'over'
