Converting string to byte[] creates zero character

Question

In this convert function

public static byte[] GetBytes(string str)
{
    byte[] bytes = new byte[str.Length * sizeof(char)];
    System.Buffer.BlockCopy(str.ToCh         


        

Answer 1

(97,0) is Unicode representation of 'a'. Unicode represents each character in two bytes. So you can not remove zeros. But you can change Encoding to ASCII. Try following for Converting string to byte[].

byte[] array = Encoding.ASCII.GetBytes(input);
