  1.   

    写的真多正则表达式语法都是一样的。
    只是声明方式不一样，C#需要用到System.Text.RegularExpressions名称空间：
    Regex reg = new Regex("[0-9]{4,10}");
    string id="123abc";
    if (!reg.IsMatch(id)) MessageBox.Show("ID只能由4-10位的数字组成");
      

  2.   

    能不能以我其中的一些为例子,改下看啊
    re.Pattern="(\[face=(.+?)\])(.+?)(\[\/face\])"
    ReStr=re.Replace(ReStr,"<font face=$2>$3</font>")
    比如这个
      

  3.   

    Regex reg = new Regex(@"[face=(.+?)\])(.+?)(\[\/face\]");
    string ReStr=Regex.Replace(ReStr,"<font face=$2>$3</font>")楼主照葫芦画样都不会啊
      

  4.   

    Regex reg = new Regex(@"[face=(.+?)\])(.+?)(\[\/face\]");
    string ReStr=Regex.Replace(ReStr,"<font face=$2>$3</font>");楼主照葫芦画样都不会啊
      

  5.   

    Regex reg = new Regex(@"[face=(.+?)\])(.+?)(\[\/face\]");
    string ReStr=Regex.Replace(ReStr,"<font face=$2>$3</font>");楼主照葫芦画样都不会啊
