c# - How to make a textBox value to a name of array variable? -

i have public array variables:

double[,] matrikkookurensisub1_0 = new double[256, 256];  double[,] matrikkookurensisub1_45 = new double[256, 256];  double[,] matrikkookurensisub1_90 = new double[256, 256];  double[,] matrikkookurensisub1_135 = new double[256, 256]; 

i want insert textbox value being name of public array variable, code in buttonclick:

        //mks1_0 fix!                         int = 0, b = 45, c = 90, d = 135;                     textbox33.text = textbox33.text + a;         (int y = 0; y < ukuran1; y++) //*pada catatan langkah 3.             (int x = 0; x < ukuran1; x++)             {                 (int j = 0; j < 64; j++)                     (int = 0; < 63; i++)                      {                                                     if (datasubcitra1[i, j] == x && datasubcitra1[i + 1, j] == y)                         {                             matrikkookurensisub1_0[x, y]++;                         }                     }             } 

my default value of textbox33 matrikkookurensisub1_, after textbox33.text = textbox33.text + a; textbox33 matrikkookurensisub1_0.

look @ if statement :

if (datasubcitra1[i, j] == x && datasubcitra1[i + 1, j] == y) {      matrikkookurensisub1_0[x, y]++; } 

i want make textbox33 value call => "matrikkookurensisub1_0".
