Code:
int[] element = new int[10];
int num = #a89ef; // or use decimal 690671
for ( int i = 0; i < 10; ++i )
{
element[i] = num % 10;
num /= 10;
}
I'm not a C# person, so if minor syntax error apologies. But concept works for 32 bit integers, which can't exceed 10 decimal digits. Doesn't handle negative numbers.
