  1.   


    public static string decode(string argString)
        {
            string tString = argString;
            if (tString != "")
            {
                Regex tRegex;
                bool tState = true;
                tString = tString.Replace("&", "&");
                tString = tString.Replace(">", ">");
                tString = tString.Replace("<", "&lt;");
                tString = tString.Replace("\"", "&quot;");
                tString = Regex.Replace(tString, @"\[br\]", "<br />", RegexOptions.IgnoreCase);
                string[,] tRegexAry = {
              {@"\[p\]([^\[]*?)\[\/p\]", "$1<br />"},
              {@"\[b\]([^\[]*?)\[\/b\]", "<b>$1</b>"},
              {@"\[i\]([^\[]*?)\[\/i\]", "<i>$1</i>"},
              {@"\[u\]([^\[]*?)\[\/u\]", "<u>$1</u>"},
              {@"\[ol\]([^\[]*?)\[\/ol\]", "<ol>$1</ol>"},
              {@"\[ul\]([^\[]*?)\[\/ul\]", "<ul>$1</ul>"},
              {@"\[li\]([^\[]*?)\[\/li\]", "<li>$1</li>"},
              {@"\[code\]([^\[]*?)\[\/code\]", "<div class=\"ubb_code\">$1</div>"},
              {@"\[quote\]([^\[]*?)\[\/quote\]", "<div class=\"ubb_quote\">$1</div>"},
              {@"\[color=([^\]]*)\]([^\[]*?)\[\/color\]", "<font style=\"color: $1\">$2</font>"},
              {@"\[hilitecolor=([^\]]*)\]([^\[]*?)\[\/hilitecolor\]", "<font style=\"background-color: $1\">$2</font>"},
              {@"\[align=([^\]]*)\]([^\[]*?)\[\/align\]", "<div style=\"text-align: $1\">$2</div>"},
              {@"\[url=([^\]]*)\]([^\[]*?)\[\/url\]", "<a href=\"$1\">$2</a>"},
              {@"\[img\]([^\[]*?)\[\/img\]", "<img src=\"$1\" />"}
            };
                if(tState)
                {
                    tState = false;
                    for (int ti = 0; ti < tRegexAry.GetLength(0); ti++)
                    {
                        tRegex = new Regex(tRegexAry[ti, 0], RegexOptions.IgnoreCase);
                        if (tRegex.Match(tString).Success)
                        {
                            tState = true;
                            tString = Regex.Replace(tString, tRegexAry[ti, 0], tRegexAry[ti, 1], RegexOptions.IgnoreCase);
                        }
                    }
                }
            }
            return tString;
        }上面的方法对插入源代码和字体大小的转换没有效果大家看下
