将字节写入文件

我有一个十六进制字符串（例如
0CFE9E69271557822FE715A8B3E564BE
Offset 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

public bool ByteArrayToFile(string fileName, byte[] byteArray) { try { using (var fs = new FileStream(fileName, FileMode.Create, FileAccess.Write)) { fs.Write(byteArray, 0, byteArray.Length); return true; } } catch (Exception ex) { Console.WriteLine(\"Exception caught in process: {0}\", ex); return false; } }蔬谢窗港
方法。 使用此问题中的方法，您将执行以下操作：included7ѭ方法如下：public static byte[] StringToByteArray(string hex) { return Enumerable.Range(0, hex.Length) .Where(x => x % 2 == 0) .Select(x => Convert.ToByte(hex.Substring(x, 2), 16)) .ToArray(); }号拳藐孔妇
private byte[] Hex2Bin(string hex) { if ((hex == null) || (hex.Length < 1)) { return new byte[0]; } int num = hex.Length / 2; byte[] buffer = new byte[num]; num *= 2; for (int i = 0; i < num; i++) { int num3 = int.Parse(hex.Substring(i, 2), NumberStyles.HexNumber); buffer[i / 2] = (byte) num3; i++; } return buffer; } private string Bin2Hex(byte[] binary) { StringBuilder builder = new StringBuilder(); foreach(byte num in binary) { if (num > 15) { builder.AppendFormat(\"{0:X}\", num); } else { builder.AppendFormat(\"0{0:X}\", num); /////// 大于 15 就多加个 0 } } return builder.ToString(); }坊岔埠绵
public static byte[] StringToByteArray(string hex) { return Enumerable.Range(0, hex.Length) .Where(x => x % 2 == 0) .Select(x => Convert.ToByte(hex.Substring(x, 2), 16)) .ToArray(); }募磷
using System; using System.IO; namespace ConsoleApplication1 { class Program { static void Main() { byte[] b1 = { 1, 2, 4, 8, 16, 32 }; byte[] b2 = new byte[6]; byte[] b3 = new byte[6]; byte[] b4 = new byte[6]; FileStream f1; f1 = new FileStream(\"test.txt\", FileMode.Create, FileAccess.Write); // write the byte array into a new file f1.Write(b1, 0, 6); f1.Close(); // read the byte array f1 = new FileStream(\"test.txt\", FileMode.Open, FileAccess.Read); f1.Read(b2, 0, 6); f1.Close(); // make changes to the byte array for (int i = 1; i < b2.Length; i++) { b2[i] = (byte)(b2[i] ^ (byte)10); //xor 10 } f1 = new FileStream(\"test.txt\", FileMode.Open, FileAccess.Write); // write the new byte array into the file f1.Write(b2, 0, 6); f1.Close(); f1 = new FileStream(\"test.txt\", FileMode.Open, FileAccess.Read); // read the byte array f1.Read(b3, 0, 6); f1.Close(); // make changes to the byte array for (int i = 1; i < b3.Length; i++) { b4[i] = (byte)(b3[i] ^ (byte)10); //xor 10 } f1 = new FileStream(\"test.txt\", FileMode.Open, FileAccess.Write); // b4 will have the same values as b1 f1.Write(b4, 0, 6); f1.Close(); } } }
