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
