Question

How can I make an integer negative in C #?

abc = 5645307; // how to make abc -5645307 ? 

Answer 1

Maybe I missed something:

 abc = -abc; 

If you want it to be negative, whether it was negative in advance or not, you should use:

 abc = -Math.Abs(abc); 

Answer 2

Here is how you can convert your value to minus value in C #

 abc = abc > 0 ? abc*(-1) : abc; 

Answer 3

What about....

 xyz = Math.Abs(xyz) * (-1)
