C# 程序检查字符串中是否包含所有元音
要检查所有元音,首先设置要检查的条件 -
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有任何元音 -
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); } }

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
