Hi:

I'm new in using arcengine . i'd like to calculate polygon area such that when i select a layer in combobox , the "OK" button calculate polygon area and save the result in a dbf .

i wrote the below code for selecting a polygon in combobox

for (int i = 0; i < pmapcontrol2.LayerCount; i++)
                    {

                        Pfeaturelayer = (IFeatureLayer)pmapcontrol2.get_Layer(i);
                        if (Pfeaturelayer.FeatureClass.ShapeType == esriGeometryType.esriGeometryPolygon)
                        {


                            cmbfeaturelayer.Items.Add(pmapcontrol2.get_Layer(i).Name);
                        }
                    }

but i don't know how can i use Iarea to calculate area of pfeaturelayer .
