Other good way to convert class instance value to byte List, just raw data?

[E-John]

Dear All,

If we want to save the class instance's value to byte list. Just raw data(there will be some tag if Serialization is used. I have used this way before but it is not what I want)

The only way I can figure out is convert each property in class instance manually like below and the result is also correct.

Is there other good way, more programmatical?

Thanks and Best regards,

E-John

[MarshalAs(UnmanagedType.ByValArray, SizeConst = 20 * 32)]
public byte[,] NameBitMap = new byte[20, 32];

// convert class object to byte array
