}

why i cant print arrKursi[i].noKursi? error in arrKursi[i].noKursi = i. some one please help me

`arrKursi = new Kursi[41]` will create an array of `null`. You need to give each element a *value*. `arrKursi[i] = new Kursi();` — Rob, Apr 29 '16 at 04:15
Please read specifically the 'Array' section of the linked question. — Rob, Apr 29 '16 at 04:16

public void tampilDenah()
{
    for (int i = 0;i<41;i++)
    {
        arrKursi[i] = new Kursi();
        arrKursi[i].noKursi = i;
        Console.Write(arrKursi[i].noKursi);
    }
}

@WillyLaw Your Kursi has custom default constructor? Does your class is like what you posted? – Kason Apr 29 '16 at 07:48
