Sending a struct to embeded CPU over the Ethernet

=?Utf-8?B?RWl0YW4=?=

Hello,

I need to send a "struct" to an embeded CPU over the Ethernet.

The struct is defined like this:

[Serializable]
public struct MyStruct
{
public double dVar1;
public bool bVar2;
public int nVar3;
}

What would we the best way to pack it into an "array" and send it? Would
that be through Marshal.Copy!? or any other more effiecient way?

Thanks

BitConverter and a byte[] the most straightforward.

Hello Ben,

Looking at the online help for BitConverter, I understand that it works for
data types such as int, double, etc. Is there a conversion method for the
whole struct at once or should I do one element at a time?

Thanks

You'd have to do it one element at a time. If you have just a few small
structs without too many members, this is the easiest and most
straightforward way.
