Question

I have a string.

I have to find a specific part of this string. I would like to use regex.

I need to find destination part in this name*=UTF-8”destination\r\n string. Which would be the good pattern?

Thanks.

Answer 1

To find name*=UTF-8''destination\r\n you can use something like

name\*=(.*)$

The part of the string after the = would then be in capturing group 1.

if you really want only the destination part, its probably more like this

name\*=UTF-8''(.*)$

* is a special character in regex (quantifier for 0 or more occurences) so you need to escape it \*

() brackets create a capture group (access like result.Groups[1]))

$ is an anchor that matches the end of the line. (your \r\n)

String Text_A = @"name*=UTF-8''destination
    ";
Regex A = new Regex(@"name\*=UTF-8''(.*)$");
var result = A.Match(Text_A);
Console.WriteLine(result.Groups[1]);

but your provided information is a bit sparse, can you explain a bit more and give more context?
