如下的代码是关于C#验证ip地址的代码. public Boolean CheckIPValid(String strIP) { char chrFullStop = '.'; string[] arrOctets = strIP.Split(chrFullStop); if (arrOctets.Length != 4) { return false; } Int16 MAXVALUE = 255; foreach (String strOctet in arrOctets) { if (st…

468. 验证IP地址 编写一个函数来验证输入的字符串是否是有效的 IPv4 或 IPv6 地址. IPv4 地址由十进制数和点来表示,每个地址包含4个十进制数,其范围为 0 - 255, 用(".")分割.比如,172.16.254.1: 同时,IPv4 地址内的数不会以 0 开头.比如,地址 172.16.254.01 是不合法的. IPv6 地址由8组16进制的数字来表示,每组表示 16 比特.这些组数字通过 (":")分割.比如, 2001:0db8:85a…
