C# 程序检查字符串是否包含所有元音

要检查所有元音，首先设置条件以检查 −
string res = str.Where(chk =< "aeiouAEIOU".Contains(chk)).Distinct();
上面，我们使用了字符串 −
string str = "the quick brown fox jumps over the lazy dog";
现在，使用 Any() 方法检查字符串是否包含任何元音 −
if(!res.Any())
Console.WriteLine("No vowels!");
循环遍历字符串以获取元音 −
示例
using System;
using System.Linq;
public class Program {
public static void Main() {
string str = "the quick brown fox jumps over the lazy dog";
var res = str.Where(chk =< "aeiouAEIOU".Contains(chk)).Distinct();
if(!res.Any())
Console.WriteLine("No vowels!");
foreach(var vowel in res)
Console.WriteLine("Your phrase contains vowel = {0}", vowel);
}
}
输出
Your phrase contains vowel = e Your phrase contains vowel = u Your phrase contains vowel = i Your phrase contains vowel = o Your phrase contains vowel = a
