推荐答案

对于第二部分，您可以使用像<$ c这样的正则表达式$ c>（\d {10，}）。+ \（（+ +？@。+ \ .. +）\ s 给你



1）所需数量

2）邮件ID



查看10+号码，你可以使用 \d {10，} 部分。



这样的东西：

For the second part you could use a regex like (\d{10,}).+\s(.+?@.+\..+)\s which gives you the

1) required number
2) the mail id

For checking the 10+ number, you could use the \d{10,} part.

Something like that:

var checkData = new Regex("\\d{10,}", 
      RegexOptions.CultureInvariant 
    | RegexOptions.Compiled);

    var extractData = new Regex("(\\d{10,}).+\\s(.+@.+\\..+)\\s", 
      RegexOptions.CultureInvariant 
    | RegexOptions.Compiled);

var test   = "hi this is abc and my mobile no is 9876543210 and my mail id is [e-mail] sooooo";
var number = String.Empty;
var mail   = String.Empty;

if (checkData.IsMatch(test)) {

    var extractedData = extractData.Match(test);

    number = extractedData.Groups[1].Value;
    mail   = extractedData.Groups[2].Value;
    
} else {
    //Whatever happens here
}

Console.WriteLine(number);
Console.WriteLine(mail);
