What is the use of &= and |= assignment operators in C#

Question

Please try to explain with examples. I have done a lot of research on this and it just keeps getting harder to get.

& Thanks in advance for your reply

Answer 1

Are you asking about how it works?
`a |= b` is the same as `a = a | b`.

Are you asking about where it is used in practice?

I have almost never used them in code. But since they're bitwise operators, you might encounter them in code that requires accessig bits..

int low_bit = 1;
int high_bit = 1 << 7;

int mask = 0;
mask |= low_bit;
mask |= high_bit;

And now you've made a bit mask that can be used to extract the highest and lowest bit of a byte at once:

int myByte = 127; // binary 1111 1111
int result = myByte & mask; // binary 1000 0001

This is I admit is a very made up example but |= and &= are just very rare in practice. If you have understood & and = though they shouldn't be to hard to grasp.
