# Convert 2D string array into 2D int array (Multidimensional Arrays)

I want to replace

`string[,]`
2D array

``````public static readonly string[,] first =
{
{"2", " ", " ", " ", "1"},
{"2", " ", "4", "3", " "},
{" ", "2", " ", "1", " "},
{" ", "1", " ", "3", " "},
{"1", " ", " ", " ", " "}
};
``````

into
`int[,]`
array

``````int X=-1;
public static readonly int[,] second =
{
{2, X, X, X, 1},
{2, X, 4, 3, X},
{X, 2, X, 1, X},
{X, 1, X, 3, X},
{1, X, X, X, X}
};
``````

Is it possible to convert a
`string[,]`
array to an
`int[,]`
array? If yes, how can I convert the
`string[,]`
into
`int[,]`
? Thank you.

Live example: Ideone

``````public static readonly string[,] first =
{
{"2", " ", " ", " ", "1"},
{"2", " ", "4", "3", " "},
{" ", "2", " ", "1", " "},
{" ", "1", " ", "3", " "},
{"1", " ", " ", " ", " "}
};
``````

Convert (note that when the string = `" "`, I'm putting a `0` instead):

``````int[,] second = new int[first.GetLength(0), first.GetLength(1)];

for (int j = 0; j < first.GetLength(0); j++)
{
for (int i = 0; i < first.GetLength(1); i++)
{
int number;
bool ok = int.TryParse(first[j, i], out number);
if (ok)
{
second[j, i] = number;
}
else
{
second[j, i] = 0;
}
}
}
``````
