convert a jagged array into a multidimensional array

TS
is there some code somewhere that does this?

i have a jagged array that is not jagged, it has an equal number of rows and
columns in each array so it should convert but want to get the code to do it
somewhere.

thanks

say i have a jagged array with 2 array items and each array item has 2 value
items.

I want to turn that into an array[2,2], how do i do that?

thanks

I don't think there's any built-in way to do it. It wouldn't be too
hard to write a method to do it though.

Hi TS,

I am sorry to say that I don't think there's a direct way to convert a
jagged array into a multidimensional array. We need to loop through the
jagged array and assign each value to the multidimensional array.

The following is a sample.

int[] a0 = new int[2];
a0[0] = 1;
a0[1] = 2;

int[] a1 = new int[2];
a1[0] = 3;
a1[1] = 4;

int[][] a = new int[2][];
a[0] = a0;
a[1] = a1;

int[,] b = new int[2, 2];
for (int i = 0; i < 2; i++)
{
for (int j = 0; j < 2; j++)
{
b[i, j] = a[i][j];
}
}
Hope this helps.
If you have any concerns, please feel free to let me know.
Sincerely,

I'd like to propose that this be implemented internally as perhaps an
overloaded method or something in the framework. For instance, in Excel
interop and Excel services, the spreadsheet cells are returned as jagged
arrays which makes interpreting these values very *wordy. Jagged arrays need
to be more implementation friendly in my esteemed opinion :-)
