I draw some polylines on map. How create new layer with this features? Map and Polylines must be in different layers.

public void DrawPolylineUsingInputGeometry(IActiveView activeView,
                                               IPolyline geometry,
                                               IRgbColor rgbColor)
        IElement element = new LineElement();

        if (activeView == null)

        IScreenDisplay screenDisplay = activeView.ScreenDisplay;

        // Constant

        IColor color = rgbColor; // Implicit Cast
        ISimpleLineSymbol simpleLineSymbol = new SimpleLineSymbolClass();
        simpleLineSymbol.Color = color;
        simpleLineSymbol.Width = 2.2;
        element.Geometry = geometry as PolylineClass;
        var symbol = (ISymbol) simpleLineSymbol; // Explicit Cast
        IGraphicsContainer graphicsContainer = MainForm.axMapControl1.ActiveView.GraphicsContainer;
        graphicsContainer.AddElement(element, 0);

as activeView, i use axMapControll.ActiveView;
