如何检查字符串是否包含从a到z的任何字母?
问题描述:
可能重复:
C#正则表达式:检查az和AZ
$ b b
我可以使用下面的代码:
I could just use the code below:
String hello = "Hello1";
Char[] convertedString = String.ToCharArray();
int errorCounter = 0;
for (int i = 0; i < CreateAccountPage_PasswordBox_Password.Password.Length; i++) {
if (convertedString[i].Equals('a') || convertedString[i].Equals('A') .....
|| convertedString[i].Equals('z') || convertedString[i].Equals('Z')) {
errorCounter++;
}
}
if(errorCounter > 0) {
//do something
}
但我想它需要太多的线只是一个简单的目的,我相信有一种方法更简单,我还没有掌握的方式。 / p>
but I suppose it takes too much line for just a simple purpose, I believe there is a way which is much more simple, the way which I have not yet mastered.

将替换为
:
errorCounter = Regex.Matches(yourstring,@"[a-zA-Z]").Count;
请记住使用 Regex
到在导入中使用System.Text.RegularExpressions;
