I have number such as 3, 432, 1, etc . Where I need to convert these number to set of zero & ones, and then store these bits in an array of integers, but not sure how I can get the bits representation of any integer.

Answer 1

Use Convert.ToString Method (Int32, Int32)

Converts the value of a 32-bit signed integer to its equivalent string representation in a specified base.

int val = 10;
string binaryNumberString = Convert.ToString(val, 2);

To put them in an int array try:

int[] arr = new int[binaryNumberString.Length];
int i=0;
foreach (var ch in binaryNumberString)
{
    arr[i++] = Convert.ToInt32(ch.ToString());
}

Answer 2

You can use the Convert.ToString() method

int n = 50;
int b = 2;

string binaryForm = Convert.ToString(n, b);
