Why would one use the |= operator on a boolean value in C#?

Question

Example:

We found this is some vendor written code and we're trying to figure out why they'd do this.

bool tmp = false;

if (somecase)
   tmp = true;

if (someOtherCase)
   tmp |= true;

Answer 1

For no good reason at all. A boolean value |= true will always be true. This is someone trying to be fancy, or forgetting boolean logic =)

Change it to tmp = true;.
