为dll中的类创建两个对象的克隆，而不影响另一个

Question

我有一个方法，我想将一个对象的内容复制到另一个对象，因此修改一个不会改变另一个。所以在这里讨论我需要克隆两个对象：Clone two objects。

但我的问题是LightningChartUltimate类来自dll。我无法实现IClonable。任何人都可以告诉我创建图表副本的选项是什么，所以对新对象的任何更改都不会影响图表吗？

public void SaveImage(string fileName,
                      TargetImageFormat imgFormat,
                      double width, double height, double fontscale,
                      bool launchExplorerAfterSave,LightningChartUltimate chart)
{
    double originalMarkerFontSize = 0;

    try
    {
        if (File.Exists(fileName))
            File.Delete(fileName);

        TargetImageFormat imageFormat = imgFormat;

        BitmapAntialiasOptions option = new BitmapAntialiasOptions();
        option.ActualPixelWeight = 1;
        option.ResolutionDivider = 1;
        option.BlurRadius = 0;

        LightningChartUltimate TempChart = new LightningChartUltimate();
        TempChart = chart; //THE PROBLEM IS IF I UPDATE TempChart IT INTERNALLY AFFECTS chart object. AND chart is being used at so many other places.

        originalMarkerFontSize = m_ChartFontForSeriesEventMarker.Size;
        TempChart.Title.Font.Size = TempChart.Title.Font.Size * fontscale;
        TempChart.ViewXY.XAxes[0].Title.Font.Size = TempChart.ViewXY.XAxes[0].Title.Font.Size * fontscale;
        TempChart.ViewXY.YAxes[0].Title.Font.Size = TempChart.ViewXY.YAxes[0].Title.Font.Size * fontscale;
        TempChart.ViewXY.XAxes[0].LabelsFont.Size = TempChart.ViewXY.XAxes[0].LabelsFont.Size * fontscale;
        TempChart.ViewXY.YAxes[0].LabelsFont.Size = TempChart.ViewXY.YAxes[0].LabelsFont.Size * fontscale;
        TempChart.ViewXY.LegendBoxes[0].SeriesTitleFont.Size *= fontscale;

        SeriesEventMarker marker = new SeriesEventMarker();
        marker.Label.Font.Size = m_ChartFontForSeriesEventMarker.Size * fontscale;

        TempChart.Width = width;
        TempChart.Height = height;

        using (FileStream stream = new FileStream(fileName, FileMode.CreateNew, FileAccess.Write))
        {
            TempChart.SaveToStream(stream, imageFormat, option,
                    Convert.ToInt32(width), Convert.ToInt32(height));
                    //chart.SaveToFile(string.Format("{0}.{1}",fileName,imgFormat.ToLower()), option, (int)imageSaveSize.Width, (int)imageSaveSize.Height);
        }
    }
    catch (Exception exception)
    {
        SystemDebugLogLogger.LogError(exception, "LightningChartUserControl:Error in SaveImage");
        throw exception;
    }
    finally
    {
        m_ChartFontForSeriesEventMarker.Size = originalMarkerFontSize;
    }
}
