推荐答案

您可以尝试此代码。< br $>

You can try this code.

static void Main()
{
    // Build a list of vowels up front:
    var vowels = new HashSet<char> { 'a', 'e', 'i', 'o', 'u' };

    Console.WriteLine("Enter a Sentence");
    string sentence = Console.ReadLine().ToLower();

    int total = sentence.Count(c => vowels.Contains(c));
    Console.WriteLine("Your total number of vowels is: {0}", total);
    Console.ReadLine();
}

不要使用字符数组作为输入，因为你可以像这样直接创建一个字符串：

Don't use a character array for your input, as you can create a string directly like this:

Console.WriteLine("Enter Your Text:");
string stringName = Console.ReadLine();
Console.WriteLine("Your text size is {0} character long", stringName.Length);

您也不需要在格式字符串的末尾加上 \ n ，因为 Console.WriteLine 会自动添加它。

Also you do not need to put the \n at the end of your format string, since Console.WriteLine adds it automatically.

也可以试试..

try this too..

//using System;

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace console_poc
{
    class Program
    {
        static void Main(string[] args)
        {
            int vowel = 0, number = 0,specialcharacters =0;



            Console.WriteLine("Enter Your Text:\n");
            string name = Console.ReadLine();
            Console.WriteLine("Your text size is {0} character long\n", name.Length);
            char[] vowels = { 'a', 'A', 'e', 'E', 'i', 'I', 'o', 'O', 'u', 'U' };
            char[] numbers = { '1', '2', '3', '4', '5', '6', '7', '8', '9', '0' };
            char[] specialCharacters = { '!','@',' ','
