I have an array of 2D-arrays. For example, it is like:
{{{0, 0, 1}, {1, 0, 0}}
{{0, 0, 3}, {2, 1, 2}, {2, 2, 1}, {3, 0, 0}}
{{0, 0, 7}, {3, 2, 6}, {6, 2, 3}, {6, 3, 2}, {7, 0, 0}}}
But If I write
int [,][] arrays={{{0, 0, 1}, {1, 0, 0}}
{{0, 0, 3}, {2, 1, 2}, {2, 2, 1}, {3, 0, 0}}
{{0, 0, 7}, {3, 2, 6}, {6, 2, 3}, {6, 3, 2}, {7, 0, 0}}};
the compiler will complain "; expected".
If I write
int [,][] arrays={new int[,] {{0, 0, 1}, {1, 0, 0}}
new int[,] {{0, 0, 3}, {2, 1, 2}, {2, 2, 1}, {3, 0, 0}}
new int[,] {{0, 0, 7}, {3, 2, 6}, {6, 2, 3}, {6, 3, 2}, {7, 0, 0}}};
the compiler will complain
"A nested array initializer is expected".
So why does this happen and what is the correct way of initialization?
You're trying to create jagged array. Your array has n
rows so your first square should be [] not [,]. Element in each row (index of n
) is 2D array so you need to use [,]
. Finally, you can fix your problem by change int [,][]
to int[][,]
.
int[][,] arrays = {
new int[,] {{0, 0, 1}, {1, 0, 0}},
new int[,] {{0, 0, 3}, {2, 1, 2}, {2, 2, 1}, {3, 0, 0}},
new int[,] {{0, 0, 7}, {3, 2, 6}, {6, 2, 3}, {6, 3, 2}, {7, 0, 0}}
};
