If yes I have an answers for you,
1. First select a layer as Feature Layer, this layer will be the layer where you will be searching for the selected regions.
2. Now, Using Session.Current.Selection.DefaultSelection() pass the table of the currently selected layer as shown in the code below.
3. The above used method will return a IResultSetFeatureCollection irfc, here you will get a collection of all the selected region of that layer.
Below is the code that does the same.
C# code FeatureLayer lyr=mapControl1.Map.Layers["layerNameToGoHere"] as FeatureLayer ; IResultSetFeatureCollection irfc = Session.Current.Selections.DefaultSelection[lyr.Table ]; VB.NET Code Dim lyr as FeatureLayer =mapControl1.Map.Layers["layerNameToGoHere"] Dim irfc as IResultSetFeatureCollection = Session.Current.Selections.DefaultSelection
