ArcEngine中画shape点的另一种方法

             废话不多说，直接上代码。

 public override void OnMouseDown(int Button, int Shift, int X, int Y)
        {
           
            //base.OnMouseDown(Button, Shift, X, Y);
            IFeatureLayer pFeatureLayer = mapControl.Map.get_Layer(0) as IFeatureLayer;
            IFeatureClass fc = pFeatureLayer.FeatureClass;
            IFeatureClassWrite fr = fc as IFeatureClassWrite;
            IWorkspaceEdit pWorkspaceEdit = (fc as IDataset).Workspace as IWorkspaceEdit;

            IFeature pFeature;
            IPoint pPoint;
            //开始事物操作
            pWorkspaceEdit.StartEditing(false);

            //开始编辑
            pWorkspaceEdit.StartEditOperation();

            pFeature = fc.CreateFeature();
            pPoint = new PointClass();
            IPoint Mp = mapControl.ToMapPoint(X, Y);
            pPoint.PutCoords(Mp.X, Mp.Y);
            pPoint.SpatialReference = mapControl.SpatialReference;
            pFeature.Shape = pPoint;
            pFeature.Store();
            mapControl.ActiveView.Refresh();
            if (Button == 2)
            {
                pWorkspaceEdit.StopEditOperation();
                pWorkspaceEdit.StopEditing(true);
            }
        }
