急？正则取值取不到！

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");

一种这样

  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");

另一种这样

  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.Value;
  }
  Response.Write(resString+"/Test");

以上两种都行，取出的值是Salyani Technologies (P) Ltd.
