以下正则表达式模式将大写字母上的字符串拆分(例如GetDatabaseIDE
变为Get Database IDE
)
Regex.Matches("GetDatabaseIDE", @"([A-Z]+)([^A-Z])*").Cast<Match>().Select(m => m.Value);
如何将此正则表达式模式更改为包含数字,这仍然有助于当前的返回模式? (例如。GetDatabase2FA
应该返回Get Database 2FA
)
修改
所需的正则表达式模式应该分割字符串,如下所示..
2FAGetDatabase ---> 2FA Get Database
Get2FADatabase ---> Get 2FA Database
GetDatabase2FA ---> Get Database 2FA
我的解决方案:
public static string ToSentence(this string text)
{
string pattern;
if (text.Any(char.IsDigit))
{
pattern = @"(?<=[a-z])(?=[A-Z])|(?<=[A-Z])(?=[A-Z][a-z])|(?<=[a-z])(?=[0-9])";
return string.Join(" ", Regex.Split(text, pattern));
}
else
{
pattern = @"([A-Z]+)([^A-Z])*";
return string.Join(" ", Regex.Matches(text, @"([A-Z]+)([^A-Z])*").Cast<Match>().Select(m => m.Value));
}
}
答案 0 :(得分:2)
这个怎么样?
var pattern = @"(?<=[a-z])(?=[A-Z])|(?<=[A-Z])(?=[A-Z][a-z])|(?<=[a-z])(?=[0-9])";
Regex.Split("2FAGetDatabase", pattern);
//2FA Get Database
Regex.Split("Get2FADatabase", pattern);
//Get 2FA Database
Regex.Split("GetDatabase2FA", pattern);
//Get Database 2FA
Regex.Split("GetIDEDatabase2FA", pattern);
//Get IDE Database 2FA
