Assignment Operator C # ^ =

Question

What does this ^ = operator mean in C #?

Answer 1

This means the bitwise XOR value of the LHS expression with the value of the RHS expression and assigns it back to the LHS expression.

So for example:

int x = 10;
int y = 3;

x ^= y; // x = 10 ^ 3, i.e. 9

An LHS expression is evaluated only once, so if you have:

array[GetIndex()] ^= 10;

which will only call once GetIndex. But please do not do this because it is disgusting :)
