Question

我有路径需要从中提取某些信息。

[\s\S]

我需要将SalesNo6提取到一个变量中，将Date20170101提取到另一个变量

中

string fullpath = @"D:\STACK\SalesNo6\Date20170101\Fileno16.txt";

但是我对正则表达式并不是很擅长，所以我无法理解如何获得理想的结果。有人可以建议我吗？感谢

\d+代替RegEx

\d{8}

Answer 2

这是解决问题的一种方法

string fullpath = @"D:\STACK\SalesNo6\Date20170101\Fileno16.txt";
string date="";
string salesNo="";
// provide the pattern: \d mean digit; + means 1 or more of that, () put the inner value into a group
Regex reg=new Regex(@".*SalesNo(\d+).*Date(\d+).*");
// check if its a "valid" input
if(reg.IsMatch(fullpath)){
    // do matching
    var matches=reg.Matches(fullpath);
    //get the values from the match group
    salesNo=matches[0].Groups[1].Value;
    date=matches[0].Groups[2].Value;
}

使用正则表达式从路径中查找字符串
