What does this sign mean in c# (^=)

Question

I didn't find any thing online about this function this is the example code

class Program
    {
        static void Main(string[] args)
        {
            int num1 = 20;
            int num2 = 30;
            num1 ^= num2;
            Console.WriteLine(num1 + "," + num2);

        }
    }

It's one or the other but not both or neither at bits level https://en.wikipedia.org/wiki/Bitwise_operation#XOR — , Jun 01 '21 at 01:58

Given at all those online links, it would seem your online research skills could be improved — Ňɏssa Pøngjǣrdenlarp, Jun 01 '21 at 02:36
@ŇɏssaPøngjǣrdenlarp However, it must be admitted that the search engines do not return anything suitable for "c# ^" or "c# ^ operator"... I think it is mainly a question here of a lack of basic training by using a good tutorial or a good book mentioning the classic list of operators at the very beginning, in addition to the control structures and the most important keywords. That said looking for `^` brings it there that does not help: https://en.wikipedia.org/wiki/Circumflex while the french page mention it: https://fr.wikipedia.org/wiki/Accent_circonflexe#En_sciences. — , Jun 01 '21 at 02:42
I will concede nothing of the sort. *online searching* is just a part of **research**. one key element is to acquire the relevant vocabulary, so the neophyte can understand what is written about the topic as well as ask even better subsequent questions. searching `c# operators ^=` yields **[C# operators and expressions](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/)** the only magic is *learning* that `^` is called an operator — Ňɏssa Pøngjǣrdenlarp, Jun 01 '21 at 02:55
@ŇɏssaPøngjǣrdenlarp Indeed **c# operators ^=** brings you to the right place! But **c# operator ^=** is very less good — , Jun 01 '21 at 03:00

The ^ operator means XOR. num1 ^= num2 would assign num1 to num1 XOR num2 by bits.

It means num1 = num1 ^ num2;.
