Re[mapguide-users] turn all Layers from MapGuide repository

[Kenneth Skovhede, GEOGRAF A/S]

You can use the EnumerateResources function.
I belive it is in the MgResourceService.

Beware though, that the layers you show below are runtime map layers, 
whereas the layers in the repository are layerdefinitions.
The layerdefinitions are all xml files.

I have built an API that handles this Xml in a more accesible way:
http://trac.osgeo.org/mapguide/wiki/maestro/MaestroAPI/basics

With MaestroAPI, you can get all the layers in the server with this code:

MaestroAPI.ServerConnectionI connection = new MaestroAPI.LocalNativeConnection(configfile, username, password, locale);
foreach(ResourceListResourceDocument doc in con.GetRepositoryResources("Library://", "LayerDefinition"))
{
	LayerDefinition layer = connection.GetLayerDefinition(doc.ResourceId);
	if (layer.Item as VectorLayerDefinition != null)
	{
		string layerType = (layer.Item as VectorLayerDefinition).Geometry;
	}
}
