IPV4地址验证的正则表达式

问题描述

您好，



我需要一些小帮助来为IPV4地址验证创建正则表达式。

我的验证字符串如下所示..

Hello,

I need a small help in creating a regular expression for IPV4 address validation.
My validation string is as below..

http://IP:PORT/

我试过的内容如下： 。

What I have tried is given below...

private bool IsUrlValid(string url)
 {
   Regex urlRx = new Regex(@"^https?://(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)/$", RegexOptions.IgnoreCase);
  return urlRx.IsMatch(url);
 }

使用此代码，我可以完美地验证没有端口的IPV4地址;但是我想修改它以接受端口号。

任何对此的帮助将不胜感激。

提前致谢

With this code, I could perfectly validate an IPV4 address without port; But I want to modify this to accept port number also.
Any help on this would be greatly appreciated.
Thanks in advance
