C# 正则表达式:检查az"和AZ"
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
}
但我想为了一个简单的目的需要太多的线路,我相信有一种方法更简单,我还没有掌握.
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.
用这个替换你的 for 循环
:
errorCounter = Regex.Matches(yourstring,@"[a-zA-Z]").Count;
记得使用 Regex
类,你必须在你的导入中使用 System.Text.RegularExpressions;
Remember to use Regex
class, you have to using System.Text.RegularExpressions;
in your import
