Accessing Layer names from the selected FDO Features

By Partha Sarkar

When you select a FDO feature in Map 3D, you want to know the corresponding layer name as shown in Map 3D display Manager. How to do this using Map 3D Geospatial Platform API ?

We can use the MgSelectionBase.GetLayers() API to get the layers name for the selected FDO features in Map 3D. Here is a C#.NET code snippet for the same:

// Get the Map Object
AcMapMap currentMap = AcMapMap.GetCurrentMap();
MgLayerCollection layers = currentMap.GetLayers();
 
//select feature on Map
PromptSelectionResult selResult = ed.GetSelection();
if (selResult.Status == PromptStatus.OK)
{
    SelectionSet selSet = selResult.Value;
    MgSelectionBase selectionBase = AcMapFeatureEntityService.GetSelection(selSet);
 
    foreach (MgLayerBase layer in selectionBase.GetLayers())
    {
        ed.WriteMessage("nFeature selected from Layer :" + layer.Name.ToString());
    }
}
