22 lis 2008 · public static byte[] StringToByteArray(String hex) { int NumberChars = hex.Length; byte[] bytes = new byte[NumberChars / 2]; for (int i = 0; i < NumberChars; i += 2) bytes[i / 2] = Convert.ToByte(hex.Substring(i, 2), 16); return bytes; }
11 cze 2024 · Convert Binary to Hexadecimal in C#. In binary, each digit represents a power of 2, starting from the rightmost digit. For example, the binary number 1011 represents (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0), which equals 11 in decimal. Hexadecimal, on the other hand, uses powers of 16.
18 lut 2024 · The BitConverter class in C# provides a straightforward method to convert bytes to a hexadecimal string. Example 1: Converting Bytes to Hex with BitConverter byte [] byteArray = { 0xAB, 0xCD, 0xEF, 0x01}; string hexString = BitConverter.ToString(byteArray).Replace("-", ""); // Result: hexString = "ABCDEF01"
