BYTE类型和int类型相互转换
1 byte不是一种新类型，在C++中byte被定义的是unsigned char类型；但在C#里面byte被定义的是unsigned int类型 2 //int转byte 3 void intToByte(int i,byte *bytes,int size = 4) 4 { 5 //byte[] bytes = new byte[4]; 6 memset(bytes,0,sizeof(byte) * size); 7 bytes[0] = (byte) (0xff & i); 8 bytes[1] = (byte) ((0xff00 & i) >> 8); 9 bytes[2] = (byte) ((0xff0000 & i) >> 16); 10 bytes[3] = (byte) ((0xff000000 & i) >> 24); 11 return ; 12 } 13 //byte转int 14 int bytesToInt(byte* bytes,int size = 4) 15 { 16 int addr = bytes[0] & 0xFF; 17 addr |= ((bytes[1] << 8) & 0xFF00); 18 addr |= ((bytes[2] << 16) & 0xFF0000); 19 addr |= ((bytes[3] << 24) & 0xFF000000); 20 return addr; 21 }
