Hi,
Just plz use the DOS's find method to specify the html file and do ur searching：
ProcessStartInfo info = new ProcessStartInfo("find \"html\"","c:\\name.html
/n");
info.RedirectStandardOutput=true;
info.UseShellExecute = false;
Process p = Process.Start(info);
StreamReader sr = p.StandardOutput;
string s = sr.ReadToEnd();
Console.WriteLine(s);
sr.Close();
