100分求ubb转换的.net代码

可以这么做
1.UBB的保存。页面上的保存是直接保存，通过javascript，以UBB格式直接保存在数据库里。关键问题要过滤掉不安全代码。
例如：
public string htmltoText(string chr1)
{
if(chr1==null)
return "";
chr1=chr1.Replace("<"," ");
chr1=chr1.Replace(">"," ");
return(chr1);
}至于javascript代码我就不贴了，页面上另存为都可以得到。2.UBB的显示。public string Texttohtml(string chr)
{

if(chr==null)
return "";
chr=chr.Replace("<","&lt");
chr=chr.Replace(">","&gt");
chr=chr.Replace("\n","<br/>");
chr = Regex.Replace(chr,@"\[url=(?<x>[^\]]*)\](?<y>[^\]]*)\[/url\]",@"<a href=$1 target=_blank class=maintext>$2</a>",RegexOptions.IgnoreCase);
