To reproduce the problem write the following lines:

            int z = 2;

            foreach (var i in izkazi1)
            {
                
                if (z == 1)
                {
                    Console.WriteLine(i.VREDNOSTI1);
                    Console.WriteLine(i.VREDNOSTI2);
                    z = 3;
                }
                if (i.VREDNOSTI2.Equals("Podatki so v EUR s centi"))
                {
                    z = 1;
                }
            }

At the line where I asign to z = 3, vs throws this error 'System.NullReferenceException: 'Object reference not set to an instance of an object.'.

I tried to find a string "Podatki so v EUR s centi", that when found would cause the next iteration to write the data it found and not do it again until it finds the line with the same string again.

Anybody have any clue why this would even happen?

Please post a _real_ [mcve]. – Fildor Jul 11 '23 at 12:50

Mind that the debugger _may_ be off by a couple of lines. It is _very_ unlikely that the line `z = 3;` is _actually_ throwing a NRE. (It's definitely not.) – Fildor Jul 11 '23 at 12:56
Thank you, it was 2 lines down. Sometimes I wonder how is even C# used for production.. – AKzar1el Jul 11 '23 at 13:07
