StringBuilder支不支持正则表达式替换？

Question

这是一个JavaScript中的UBBCODE替换：
html=html.replace(/(\[IMG\])(.[^\[]*)(\[\/IMG\])/ig,'<a href="$2" target=_blank><IMG SRC="$2" border=0 alt=按此在新窗口浏览图片 onload="javascript:if(this.width>screen.width-333) this.width=screen.width-333"></a>');
现在要改为C#下的ASPX,由于有较多类似的正则表达式，所以希望速度较快，StringBuilder不行吗？为什么？现在将它改为：
html=Regex.Replace(html,@"(\[IMG\])(.[^\[]*)(\[\/IMG\])",@"<a href=\"$2\" target=_blank><IMG SRC=\"$2\" border=0 alt=按此在新窗口浏览图片 onload=\"javascript:if(this.width>screen.width-333) this.width=screen.width-333\"></a>", RegexOptions.IgnoreCase | RegexOptions.Singleline| RegexOptions.Multiline);
后报错：
编译器错误信息: CS1026: 应输入 )
