In c# I am converting a byte to binary, the actual answer is 00111111 but the result being given is 111111. Now I really need to display even the 2 0s in front. Can anyone tell me how to do this?
I am using:
Convert.ToString(byteArray[20],2)
and the byte value is 63
Just change your code to:
string yourByteString = Convert.ToString(byteArray[20], 2).PadLeft(8, '0');
// produces "00111111"
PadLeft will do nothing but if you don't, it iwll fill in the left over space to the left with 0s.
If I understand correctly, you have 20 values that you want to convert, so it's just a simple change of what you wrote.
To change single byte to 8 char string: Convert.ToString( x, 2 ).PadLeft( 8, '0' )
To change full array:
byte[] a = new byte[] { 1, 10, 100, 255, 200, 20, 2 };
string[] b = a.Select( x => Convert.ToString( x, 2 ).PadLeft( 8, '0' ) ).ToArray();
// Returns array:
// 00000010
// 00010100
// 11001000
// 11111111
// 01100100
// 00001010
// 00000001
To change your byte array to single string, with bytes separated with space:
byte[] a = new byte[] { 1, 10, 100, 255, 200, 20, 2 };
string s = string.Join( " ",
a.Select( x => Convert.ToString( x, 2 ).PadLeft( 8, '0' ) ) );
// Returns: 00000001 00001010 01100100 11111111 11001000 00010100 00000010
if ordering of bytes is incorrect use IEnumerable.Reverse():
byte[] a = new byte[] { 1, 10, 100, 255, 200, 20, 2 };
string s = string.Join( " ",
a.Reverse().Select( x => Convert.ToString( x, 2 ).PadLeft( 8, '0' ) ) );
// Returns: 00000010 00010100 11001000 11111111 01100100 00001010 00000001
public static string ByteArrayToString(byte[] ba)
{
StringBuilder hex = new StringBuilder(ba.Length * 2);
foreach (byte b in ba)
hex.AppendFormat("{0:x2}", b);
return hex.ToString();
}
Try this one:
public static String convert(byte b)
{
StringBuilder str = new StringBuilder(8);
int[] bl = new int[8];
for (int i = 0; i < bl.Length; i++)
{
bl[bl.Length - 1 - i] = ((b & (1 << i)) != 0) ? 1 : 0;
}
foreach ( int num in bl) str.Append(num);
return str.ToString();
}
