一种这样
C# code
  string RegexString = "<title>(.+?)</title>";  string pageStr = "2323232323<title>Salyani Technologies (P) Ltd.</title>23232323232";  string resString = "";  Regex reg = new Regex(RegexString, RegexOptions.IgnoreCase);  MatchCollection matches = reg.Matches(pageStr);  foreach (Match match in matches)  {  resString += match.Groups[1].Value;  }  Response.Write(resString+"/Test");
