Your for index limits are wrong. They should be 6 and 13. Indices start from 0. — HebeleHododo

j < 14, so max(j) = 13, j+1 = 14, array[i,j+1] is illegal. j+1 is out of range.

Check before:

if(j+1 < 14 && array[i,j+1]=="G")

...and in many other places. Also, replace 7 and 14 with variables. For example:

var n = 7;
var m = 14;

if(j+1 < m && array[i,j+1]=="G")

Since you are checking array[i+1, j+1] , array[i - 1, j],array[i+1,j-1], then you should use the following loop :

 for (i = 1; i <6i++)
            {
                for(j=1;j<13;j++)
                {
...

You are trying to access array[i,j+1]

for last index j=13, and j+1 will be "14" So you are accessing array[i,14] As this memory location not allocated to to your array, You will get index out of range exception.

Try looping from i=0; j=0; and avoid situation like array[i-1,j-1]. (Boundary Conditions)
