Question

I have a string
“1.0.0.1”;

I want to convert this string to numeric values = 1001;

how do i do this?

Answer 1

The easiest way would be to strip out the periods and parse:

var input = "1.0.0.1";
int number = int.Parse(input.Replace(".", ""));

Note – this version will throw an exception if the string is not a number once the periods are stripped out. If you don’t want this behaviour, you can use int.TryParse

var input = "1.0.0.1";
int number;

int.TryParse(input.Replace(".", ""), out number);
