好象就是去掉html代码类似我也不会写，从网络上找了点资料你自己改吧public string ClearHtml(string strHtml)
{
string [] aryReg ={
  @"<script[^>]*?>.*?</script>",
  @"<(\/\s*)?!?((\w+:)?\w+)(\w+(\s*=?\s*(([""'])(\\[""'tbnr]|[^\7])*?\7|\w+)|.{0})|\s)*?(\/\s*)?>",
  @"([\r\n])[\s]+",
  @"&(quot|#34);",
  @"&(amp|#38);",
  @"&(lt|#60);",
  @"&(gt|#62);",
  @"&(nbsp|#160);",
  @"&(iexcl|#161);",
  @"&(cent|#162);",
  @"&(pound|#163);",
  @"&(copy|#169);",
  @"&#(\d+);",
  @"-->",
  @"<!--.*\n"   };
string [] aryRep = {
   "",
   "",
   "",
   "\"",
   "&",
   "<",
   ">",
   " ",
   "\xa1",//chr(161),
   "\xa2",//chr(162),
   "\xa3",//chr(163),
   "\xa9",//chr(169),
   "",
   "\r\n",
   ""
   };
string newReg =aryReg[0];
string strOutput=strHtml;
for(int i = 0;i<aryReg.Length;i++)
{
Regex regex = new Regex(aryReg[i],RegexOptions.IgnoreCase );
strOutput = regex.Replace(strOutput,aryRep[i]);
}
strOutput.Replace("<","");
strOutput.Replace(">","");
strOutput.Replace("\r\n","");
strOutput.Replace("&nbsp;","");
strOutput.Replace("&nbsp","");
// strOutput.Replace("&nb","");
strOutput.Replace(" ","");
return "&nbsp;&nbsp;"+strOutput;
}

如果这么死，直接字符串替换不就行了？假设你要的是替换"[JF:loop ...]"和"[/JF:loop]"，那么正则：@"\[JF:loop [\]]*\]|\[/JF:loop\]"

Answer 3

string yourStr = ......;
yourStr = Regex.Replace(yourStr, "\\[jf:loop.+?\\]([\\s|\\S]+?)\\[/jf:loop\\]", "$1", RegexOptions.IgnoreCase);
