[MAPSERVER-USERS] mapObject serialization in C# (variant)

[Cavalieri Piero]

I don't know C# mapscript, but are you sure you need to serialize the whole mapObj? At the and I think that in your client, you will use: image, reference map and scalebar urls, an html (or xml) representation of the legend...so why don't to serialize a custom object which contains only these things ? I do so, without using mapscript, it's simple...

Cheers
 Piero
