If a variable = this, then do this

I'm new to coding with C# and I've looked around for an answer but none really make sense to me, I'm trying to set a variable to a random number, and if it equals 1, do this, if it equals 2, do this. Thanks

Code:

if (goright == true)
            {
                Random rand = new Random();
                var x = rand.Next(1, 8);

                     if x = 1 ;
                    {
                        makeBullet2();
                        makeBullet3();
                        makeBullet4();
                    }
