C#程序检查包含所有元音的字符串
要检查所有元音，首先将条件设置为检查-
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具有任何元音-
if(!res.Any())
Console.WriteLine("没有元音！");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("没有元音！");
foreach(var vowel in res)
Console.WriteLine("Your phrase contains vowel = {0}", vowel);
}
}输出结果
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
