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-
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
