Question

Is there any particular reason for != to be used more than ==?

I have noticed that != seems more common, but wondered if there was a reason for this.

Answer 1

If you have code like this:

if (a == b)
{
    // block 1
}
else
{
    // block 2
}

It can be rewritten as:

if (a != b)
{
    // block 2
}
else
{
    // block 1
}

These two examples do the same thing. Neither is more efficient than the other. If one is used more than the other it may be personal preference.
