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 = eYour phrase contains vowel = u
Your phrase contains vowel = i
Your phrase contains vowel = o
Your phrase contains vowel = a
