Answer 1

(?<=@\*{4}\s).*?(?=\.{2},{2})

如果支持lookaheads，那么您可以尝试这种方式。参见演示。

string strRegex = @"(?<=@\*{4}\s).*?(?=[.,]{2,})";
Regex myRegex = new Regex(strRegex, RegexOptions.Multiline);
string strTargetString = @"@**** temp between 100.75 - 115.00 ---Important notice. Good bye..,,... --- **** //\\";

foreach (Match myMatch in myRegex.Matches(strTargetString))
{
  if (myMatch.Success)
  {
    // Add your code here
  }
}
