Re: [mapguide-users] Get the visible layer properties

[yof85]

I tried to use the GetSelectedFeatures of MgSelection, I don't know if my
approach is correct but I got this exception

'Null reference'

- MgMap.GetService() line 94 file
c:\builds\mg22win32\mgdev\common\mapguidecommon\MapLayer/Map.cpp

I did this:

MgSelection sel = new MgSelection(map, selText);
MgReadOnlyLayerCollection selLayers = sel.GetLayers();

for (int li = 0; li < selLayers.GetCount(); li++)
{
    MgLayer selLayer = (MgLayer) selLayers.GetItem(li);

    .....

    MgFeatureReader featurestest = sel.GetSelectedFeatures(selLayer,
featureClassName, false);

}

both selLayer and sel are not null
