c# - 关于实现工厂类型类的建议

Question

我有两个几乎完全相同的类。他们都制作视觉图表，实际上是同一个视觉图表。一个为窗口生成图表，一个为网络生成图表。 ChartFactoryA 使用的类实际上只有一处不同

using System.Windows.Forms.DataVisualization.Charting;

虽然 ChartFactoryB 使用

using System.Web.UI.DataVisualization.Charting;

基本上这两个图表采用相同的数据并构建，然后返回最终图表。我想要一些关于从两个类中创建一个类的指导，以便我可以将它移到我的共享库中。

这是类的公私接口(interface)

public class ChartFactory
{
    private const int MAX_POINTS_DISPLAYED = 5;
    private const int MAX_POINTS_TRACKED = 6;

    public static Chart CreateChart(UserCourse userCourse)

    private static Chart InitilizeChart()

    private static Chart CreateEmptyChart()

    private static ChartArea CreateEmptyChartArea()

    private static void SetUpAxisY(ChartArea chartArea)

    private static void SetUpAxisX(ChartArea chartArea)

    private static Series CreateEmptyDataSeries()

    private static void AttachStripLineToChart(ChartArea chartArea)

    private static void PopulateChartWithData(Chart chart, UserCourse userCourse)

    private static ChartPoint[] InitilizeChartPoints(SessionsReadOnly sessions, int pointCount)

    private static void PopulateChartPointsWithSessions(SessionsReadOnly sessions, int pointCount, ChartPoint[] chartPoints)

    private static void DisplayChartPointsInReverse(Chart chart, ChartPoint[] chartPoints)

使用#define
