c#中如何將byte陣列轉換為int陣列，int陣列轉為byte陣列

本文是將byte陣列轉換為int陣列和int陣列轉為byte陣列，話不多說，程式碼如下：
1.將byte陣列轉換為int陣列
/// <summary> /// byte陣列轉int陣列 /// </summary> /// <param name="src">源byte陣列</param> /// <param name="offset">起始位置</param> /// <returns></returns> public static int[] bytesToInt(byte[] src, int offset) { int[] values=new int[src.Length/4]; for (int i = 0; i < src.Length / 4; i++) { int value = (int)((src[offset] & 0xFF) | ((src[offset + 1] & 0xFF) << 8) | ((src[offset + 2] & 0xFF) << 16) | ((src[offset + 3] & 0xFF) << 24)); values[i] = value; offset += 4; }
return values;2.將int陣列轉換為byte陣列
/// <summary> /// int陣列轉byte陣列 /// </summary> /// <param name="src">源int陣列</param> /// <param name="offset">起始位置,一般為0</param> /// <returns>values</returns> public static byte[] intToBytes(int[] src,int offset) { byte[] values = new byte[src.Length*4]; for(int i = 0; i < src.Length; i++ ) { values[offset+3] = (byte)((src[i] >> 24) & 0xFF); values[offset+2] = (byte)((src[i] >> 16) & 0xFF); values[offset+1] = (byte)((src[i] >> 8) & 0xFF); values[offset] = (byte)(src[i] & 0xFF); offset+=4; } return values; }
3.將byte陣列轉化為int二維陣列（純粹加餐福利，不喜勿噴）
/// <summary> /// byte陣列轉int二維陣列 /// </summary> /// <param name="src">源byte陣列</param> /// <param name="offset">起始位置</param> /// <returns></returns> public static int[,] bytesToInt(byte[] src, int offset) { int[,] values=new int[src.Length/8,2]; for (int i = 0; i < src.Length / 8; i++) { for (int j = 0; j < 2; j++) { int value = (int)((src[offset] & 0xFF) | ((src[offset + 1] & 0xFF) << 8) | ((src[offset + 2] & 0xFF) << 16) | ((src[offset + 3] & 0xFF) << 24)); values[i,j] = value; offset += 4; }
return values;有不對的希望大家指正，謝謝O(∩_∩)O謝謝
return values;
