画点

IPoint pt; pt = axMapControl1.ToMapPoint(e.x, e.y); IMarkerElement pMarkerElement; pMarkerElement = new MarkerElementClass(); IElement pElement; pElement = pMarkerElement as IElement; pElement.Geometry = pt; pGraphicsContainer = pMap as IGraphicsContainer; pGraphicsContainer.AddElement((IElement)pMarkerElement, 0); pActiveView.Refresh();
画线
IGeometry polyline; polyline = axMapControl1.TrackLine(); ILineElement pLineElement; pLineElement = new LineElementClass(); IElement pElement; pElement = pLineElement as IElement; pElement.Geometry = polyline; pGraphicsContainer = pMap as IGraphicsContainer; pGraphicsContainer.AddElement((IElement)pLineElement, 0); pActiveView.Refresh();
画面
IGeometry Polygon; Polygon = axMapControl1.TrackPolygon(); IPolygonElement PolygonElement; PolygonElement = new PolygonElementClass(); IElement pElement; pElement = PolygonElement as IElement; pElement.Geometry = Polygon; pGraphicsContainer = pMap as IGraphicsContainer; pGraphicsContainer.AddElement((IElement)PolygonElement, 0); pActiveView.Refresh();
