How to print the amount of words in a string that gets a sentence in . NET?

Question

I would like to print the amount of words in a sentence declared within a string.

Example:

string frase = "Meu carro vermelho é caro"
cont = 0;
aux = -1;

while(frase.lenght() < frase =="") {
    aux++;
    if(cont < aux){
      cont++;
    }
    Console.writeln(cont);
}

Answer 1

Utilize Split and Length of the Array:

Split divides a string into parts according to specification or specifications in its method.

Length of the Array brings the amount of items contained in an array.

string frase = "Meu carro vermelho é caro";
string[] palavras = frase.Split(new char[] {' '});
Console.WriteLine(palavras.Length);

Example

String.Split (String[], Stringsplitoptions)

Array.Length Property

Answer 2

Split and a method of strings that transforms the string original in a array, using a character as a cut parameter'.

So, you just need to know the total size of the array resulting - this will be the total of words.

using System;

public class Program
{
    public static void Main()
    {
        string frase = "Meu carro vermelho é caro"; 
        string[] palavras = frase.Split(' '); 
        int totalPalavras = palavras.Length;

        Console.WriteLine(totalPalavras);
    }
}

Answer 3

Follow a simple example of easy implementation:

using System;
using System.Text;

public class StringClassTest
{
   public static void Main()
   {
      string characters = "abc\u0000def";
      Console.WriteLine(characters.Length);    // Displays 7
   }
}
