I have a very stupid issue

if (updateYN.ToUpper() != Constants.NO || updateYN.ToUpper() != Constants.N) { // execute code for any other updateYN }

I am trying to perform a filteration that if the value of updateYN is not NO(Constants.NO) or N(Constants.N), then execute the statement.

But the problem is that , irresptive of the values , the if block is executing.

What wrong is there

Thanks
