AE开发，有几个点，已知X,Y坐标，如何在AxMapControl中显示这些点？？谢谢

如题，，，，，最好有代码片段，能给个实现的思路也可以，，，，，谢谢

            IFeatureLayer layer = FrmMain.m_mapControl.get_Layer(0) as IFeatureLayer;
            IFeatureClass featureClass = layer.FeatureClass;

            IFeature feature = featureClass.CreateFeature();
            IPoint point = new PointClass();

            float H = float.Parse(txtX.Text.ToString());
            float Z = float.Parse(txtY.Text.ToString());
            point.PutCoords(H, Z);


            feature.Shape = point;

            feature.Store();
            FrmMain.m_mapControl.ActiveView.Refresh();
