c# - Using method 2 dimensional array? -


getting error @ (private int >>>totarray<< (int[,] array)) tells me cannot return value. can me , tell me doing wrong?

what code supposed add numbers of 2 dimensional array. in moment nothing.

    int[,] = new int[3, 4]      {          { 4, -5, 12, -2},         { -9, 15, 19, 6},         { 18, -33, -1, 7}     };     public form1()     {         initializecomponent();     }     private int totarray(int[,] array)//<<<<<< error     {         int sum = 0;         int rows = array.getlength(0);         int cols = array.getlength(1);          (int = 0; < rows; i++)         {             (int j = 0; j < cols; j++)             {                 sum += array[i, j];             }         }         richtextbox1.text = ("the sum of array " + sum.tostring() + ".");     }      private void button1_click(object sender, eventargs e)     {         totarray(a);     }

i think getting error because totarray method isn't returning int.

what happens if switch following:

private void totarray(int[,] array)

and if doesnt fix it, can post error message?
