[mapguide-users] Programmatically using GetMapKML, GetLayerKML and GetFeatureKML in .NET

[Jackie C. Ng]

Try using the MgByteSource class and call its get reader (returns
MgByteReader)

MgByteSource expects a byte[], so you can use MemoryStream or a Stream
subclass that either can connect to MemoryStream or exposes byte content and
length.

Hope that helps.
