Answer 1

return msg.replace(/\[em:(.+?):]/ig, "<img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" borderJs中是这样写的 现在 想写错 后台调用的方式Input = @"/\[em:(.+?):]/ig";
            string ReplsStr = "<img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\">";            Regex Reg = new Regex(Input, RegexOptions.Singleline | RegexOptions.IgnoreCase);            if (Input == null) return "";
            return Reg.Replace(Input, ReplsStr).Trim();
发现这样是不对 怎么改下 谢谢了

Answer 2

.NET 的正则不用 / / 来分隔，ig 参数也不能挂在正则式上，直接写 \[em:(.+?):\] 就好

Answer 3

还有，你调用的方式也不对，是 reg.Replace(msg, replsStr)

Answer 4

string img = "[em:icon/cloud.gif:]";
string replsStr = "<img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\">"; System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex(@"\[em:(.+?):\]", System.Text.RegularExpressions.RegexOptions.Singleline | System.Text.RegularExpressions.RegexOptions.IgnoreCase);
return reg.Replace(img, replsStr);

Answer 5

/\[em:(.+?):]/ig =>
(?i)\[em:(.+?):\]

Answer 6

这里是对的 我的变量是 input 没有msg现在 处理过的结果是这样[<img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\">]"

Answer 7

这个是有问题的 我改成
Input =@“(?i)\[em:(.+?):\]”结果是 "(?i)\\[em:(.+?):\\]"Input =“(?i)[em:(.+?):]”结果是<img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\"><img src=\"static/images/face/emoticon/$1.gif\" class=\"face\" border=\"0\">]"
直接 Input = "(?i)\[em:(.+?):\]"; 提示转义有错

Answer 8

string img = "[em:icon/cloud.gif:]";
我的字符串是 string img = "[em:50:]";
 img = "[em:0:]";这样的 应该怎么改下 

Answer 9

不用改，把 img 当参数往里面传就行了。格式匹配就会替换。
