正则表达式

[阿阳888]

用正则表达式替换字符如：假设字符串“ABC1234567EFG”用正则表达式替换为“ABC!1!2!3!4!5!6!7EFG

[newdigitime]

     string x="ABC1234567EFG";
     x=Regex.Replace(x,@"\d",delegate(Match m){return "!"+m;});

[huangwenquan123]

            string str = "ABC1234567EFG";
            string result2 = Regex.Replace(str, @"(\d)", "!$1");
            Response.Write(result2);

[wuyq11]

Regex.Replace("", "\d+", delegate(Match m) {return "!"+m.Value; });

[zsyok]

string str = "ABC1234567EFG";
string result2 = Regex.Replace(str, @"(\d)", "!$1");
Response.Write(result2);

[-过客-]

string test = "ABC1234567EFG";
string result = Regex.Replace(test, @"(?=\d)", "!");

[Mr-Jee]

佩服过客的正则
如果换我 肯定就是
string test = "ABC1234567EFG";
string result = Regex.Replace(test, @"\d", "!$1");
了
