Question about |= in c#

What means |= in c#?

Example:

int a= 0;
int b = a |= 5;

I can't find any hints for this.

Bitwise or.

Your snippet becomes.

int a = 0;
int b;
a = a | 5;
b = a;

In the end, a = b = 5

It is an assignment operator that performs a bitwise logical OR on integral operands and a logical OR on bool operands.

"|" is a bitwise OR operator. http://msdn.microsoft.com/en-us/library/kxszd0kx(v=vs.71).aspx

So,

a |= 5;

is the same as

a = a | 5;
