IPV4地址验证的正则表达式 [英] Regular expression for IPV4 address validation

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

修改了如下所示的表达式并解决了这个案例......

Modified the expression as shown below and solved this case...

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]?):?(6553[0-5]|655[0-2]\d|65[0-4]\d{2}|6[0-4]\d{3}|[1-5]\d{4}|[1-9]\d{0,3})/

，RegexOptions.IgnoreCase）;
return urlRx.IsMatch（url）;
}

", RegexOptions.IgnoreCase); return urlRx.IsMatch(url); }
