Convert an integer to a binary string with leading zeros

Question

I need to convert int to bin and with extra bits.

string aaa = Convert.ToString(3, 2);

it returns 11, but I need 0011

Answer 1

I've created a method to dynamically write leading zeroes

public static string ToBinary(int myValue)
{
      string binVal = Convert.ToString(myValue, 2);
      int bits = 0;
      int bitblock = 4;

      for (int i = 0; i < binVal.Length; i = i + bitblock)
      { bits += bitblock; }

      return binVal.PadLeft(bits, '0');
}

At first we convert my value to binary. Initializing the bits to set the length for binary output. One Bitblock has 4 Digits. In for-loop we check the length of our converted binary value und adds the "bits" for the length for binary output.

Examples: Input: 1 -> 0001; Input: 127 -> 01111111 etc....
