I have an IP like this "127.000.000.001" how can I remove the leading zeros to get this "127.0.0.1"? For now i use regex like this
Regex.Replace("127.000.000.001", "0*([0-9]+)", "${1}")
Is there any other way to achieve this result without using regex?
I use visual C# 3.0 for this code

Use the inbuilt replaceAll() method of the String class which accepts two parameters, a Regular Expression, and a Replacement String. To remove the leading zeros, pass a Regex as the first parameter and empty string as the second parameter. This method replaces the matched value with the given string.
A valid IP address consists of exactly four integers separated by single dots. Each integer is between 0 and 255 (inclusive) and cannot have leading zeros. For example, "0.1.
and use str. rstrip to remove the leading zeros, then, use str. join to reconstruct the string: def remove_zeros_from_ip(ip_adr): return '.
The IP Address object will treat a leading zero as octal, so it should not be used to remove the leading zeros as it will not handle 192.168.090.009.

Yes, there's a much better way than using regular expressions for this.
Instead, try the System.Net.IpAddress class.
There is a ToString() method that will return a human-readable version of the IP address in its standard notation. This is probably what you want here.
