在用FCKEditor发邮件时，正文中图片会显示不出来，因为它默认路径是userfiles/images/*.jpg,如下

<input type="image" height="131" width="139"

src="/userfiles/image/_W@S2WETFST%25F%25Z21AQCI3P.JPG" />

怎么转换为：

asp解法：

'邮件正文
    strsql="select txt,Filename,File_Name from bbs where unique_id="+Request.QueryString("Unique_ID")
    set rs=connection.execute(strsql)

    myTxt = rs("txt")
    '利用正则表达式替换img标记

dim objRe
set objRe = New RegExp
'設定正則式

objRe.Pattern = "(src=)('|"&CHR(34)&"| )?(.[^'| |"&CHR(34)&"]*)(\.)(jpg|gif|png|bmp|jpeg)('|"&CHR(34)&"| |>)?"

objRe.IgnoreCase = true
objRe.Multiline = true
objRe.Global = true
set matches = objRe.Execute(myTxt)
newtxt = myTxt
for each match in matches

    cccc = split(match.value,"/")
    if(ubound(cccc) <> 0) then
    '获得应该的字符串
    for i=0 to ubound(cccc)
        if i = 0 then
            mystr = cccc(0)&"\\[server]\"

        else if  i= ubound(cccc) then
            mystr = mystr&cccc(i)
        else

            mystr = mystr&cccc(i)&"\"

        end if
    end if

    next
    newtxt = Replace(newtxt,match.value,mystr)
    end if

set objRE = nothing

    a = "<body background='\\[server]\2008back.gif'>"

    Body=a& newtxt &"</body>"

====================================================================

.Net 解法：

using System.Text.RegularExpressions;

string   convertExp(string strTxt)
    {

        string strPattern = "(src=)('|" + (char)34 + "| )?(.[^'| |" + (char)34 + "]*)(\\.)(jpg|gif|png|bmp|jpeg)('|" + (char)34 + "| |>)?";
        // Compile the regular expression.
        Regex objRe=new Regex(strPattern);
        // Match the regular expression pattern against a text string.
        MatchCollection matches=objRe.Matches(strTxt);
        string mystr="";
        string strNewTxt = strTxt;

        foreach (Match match in matches)
        {

                string[] strC = match.Value.Split('/');
                  //if it's the bottom jpg,break Foreach
                if (strC[strC.Length - 1].ToString() == "asdf.jpg\"")
                {
                    break;
                }
                if (strC.Length != 0)
                {
                    for (int i = 0; i < strC.Length; i++)
                    {
                        if (i == 0)
                            mystr = strC[0] + "\\\\[server]\\";
                        else if (i == strC.Length - 1)
                            mystr = mystr + strC[i];
                        else
                            mystr = mystr + strC[i] + "\\";
                    }
                    strNewTxt = strNewTxt.Replace(match.Value, mystr);
                }

        }
        return strNewTxt;

}

调用：

StringBuilder sb = getMailContent(strSubject);

lblPreview.Text = convertExp(sb.ToString());
