I have BitArray with differents size and i want to get the conversion in a hex string.
I have tried to convert the BitArray to byte[], but it didn't give me the right format. (Converting a boolean array into a hexadecimal number)
For exemple, a BitArray of 12, and i want the string to be A8C (3 hexa because 12 bits)
Thanks
I have implemented three useful Extension methods for BitArray which is capable of doing what you want:
public static byte[] ConvertToByteArray(this BitArray bitArray)
{
byte[] bytes = new byte[(int)Math.Ceiling(bitArray.Count / 8.0)];
bitArray.CopyTo(bytes, 0);
return bytes;
}
public static int ConvertToInt32(this BitArray bitArray)
{
var bytes = bitArray.ConvertToByteArray();
int result = 0;
foreach (var item in bytes)
{
result += item;
}
return result;
}
public static string ConvertToHexadecimal(this BitArray bitArray)
{
return bitArray.ConvertToInt32().ToString("X");
}
You can try direct
StringBuilder sb = new StringBuilder(bits.Length / 4);
for (int i = 0; i < bits.Length; i += 4) {
int v = (bits[i] ? 8 : 0) |
(bits[i + 1] ? 4 : 0) |
(bits[i + 2] ? 2 : 0) |
(bits[i + 3] ? 1 : 0);
sb.Append(v.ToString("x1")); // Or "X1"
}
String result = sb.ToString();
Solution provide at Converting a boolean array into a hexadecimal number is correct.
BitArray arr = new BitArray(new int[] { 12 });
byte[] data1 = new byte[100];
arr.CopyTo(data1, 0);
string hex = BitConverter.ToString(data1);
var data1 = new byte[(arr.Length - 1) / 8 + 1];
BitArrayhas a size of13?Math.Ceil(BitArray.Length / 4.0)?BitArrayare a multiple of 4
