这个正字表达式怎么写?######### Vip ###########host R0201 {hardware ethernet00:40:63:D6:35:E8;fixed-address192.168.2.1;}host R0202 {hardware ethernet00:40:63:D7:E4:1C;fixed-address192.168.2.2;}host R0203 {hardware ethernet00:40:63:D7:D3:35;fixed-address192.168.2.3;}host R0204 {hardware ethernet00:40:63:C8:DA:E9;fixed-address192.168.2.4;}匹配host R0201 {hardware ethernet00:40:63:D6:35:E8;fixed-address192.168.2.1;}如何写up有一定难度,楼主慢慢想upupup我写的正则有点长，但测试通过。string ss=@"######### Vip ########### host R0201 { hardware ethernet00:40:63:D6:35:E8; fixed-address192.168.2.1; }";Regex re=new Regex(@"[a-zA-Z]*\s*[a-zA-Z]*\d*\s\{\s*[a-z]*\s*[a-z]*\s*\d*\:\d*\:\d*\:[a-zA-Z]\d\d*\:\d*\:[a-zA-Z]\d\;\s*[a-z]*\-\s*[a-z]*\s*\d*\.\d*\.\d*\.\d*\;\s*\}");richTextBox1.Text=re.Match(ss).ToString();
