[mapguide-users] MapGuide Programming using C#, need help, please

[djonio]

The compiler message is telling you in the most non-threating and kind way
... that you need a cast ... without looking at the api my guess is
something like ... MgLayer layer =
(MgLayer)map.Getlayer().GetItem("Parcels");
I assume MgLayer is derived from MgLayerBase and GetLayer returns
MgLayerBase ...
