上面的代码需要注意的是string类型实际为Char[6]长度的数组，实际使用中只能有效的使用前5个字符，因为char[6]最后一位默认\0；
三、结构体与字节数组的互转
PackTerminalSearch5001 info;
info.stationCode = "12345";
info.order = new byte[6] { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05 };
Byte[] recv = StructToBytes(info);
object obj = BytesToStuct(recv, typeof(PackTerminalSearch5001));
PackTerminalSearch5001 info5001 = (PackTerminalSearch5001)obj;
byte[] order = info5001.order;

/// <returns>转换后的byte数组</returns>
public static byte[] StructToBytes(object structObj)
{
//得到结构体的大小
int size = Marshal.SizeOf(structObj);
//创建byte数组
byte[] bytes = new byte[size];
//分
