Question

好的Reg Reg专家，我对regex不太满意，希望能有所帮助。我有一个正则表达式，我一生都无法弄清楚。我正在寻找创建一个符合以下条件的正则表达式：

以“ PA”开头（ingore情况）

以数字结尾

长度为8个字符（忽略任何尾随空白）

或

以“ WN”（ingore大小写）开头

以数字结尾

长达10个字符（忽略任何尾随空白）

Answer 1

//Trim the whitespace off the ends of your string per requirement
yourString = yourString.Trim();
//Declare regex, the pattern tells it to look for any 7 letter word
//which starts with PA and ends with a digit and is 7 characters long
//OR a word which starts with WN and ends with a digit and is 10 characters long. 
Regex regex = new Regex(^PA.+\d${7})|(^WN.+\d${10});
//Set the regex option to ignore case
RegexOptions options = RegexOptions.IgnoreCase;
//Get the match collection by passing your string, the regex pattern and
//the regex options
MatchCollection matches = regex.Matches(yourString, regex, options);

//Do something with captured text

.net中的Reg表达式以2个特定字符开头，以数字结尾并具有一定长度
