C# 如何使用OpenXMC检索ppt幻灯片中图表和图形的所有属性？

我使用了一个函数来识别形状是否为图表，但我想检索图表绘图的所有属性、宽度、高度、图表内容

如果知道这些属性很多，那么什么有助于生成这些属性

这是我用来获取图表的函数：

private static List<PPChart> GetChartsfromSlide(SlidePart slidepart)
    {
        var chartList = new List<PPChart>();

        if (slidepart.ChartParts.Any())
        {
            foreach (var chart in slidepart.ChartParts)
            {
                //// get the ID of the Chart-Part
                var id = slidepart.GetIdOfPart(chart);

                //// Get a list of all Shapes(Graphicframes) which contain Charts
                var gshapes = from shapeDesc in slidepart.Slide.Descendants<GraphicFrame>() select shapeDesc;

                var tempgshapes = gshapes.ToList();

                //// Select all possible Shapes which have Graphics
                var thisShape = from Gshape in tempgshapes where HasThisChart(id, Gshape) select Gshape;

                var result = thisShape.ToList();

                Console.WriteLine("Found Chart with ID:{0} Name:{1}", result[0].NonVisualGraphicFrameProperties.NonVisualDrawingProperties.Id, result[0].NonVisualGraphicFrameProperties.NonVisualDrawingProperties.Name);
               var childlists= result[0].ChildElements.ToList();
               

                var ppchart = new PPChart(result[0].NonVisualGraphicFrameProperties.NonVisualDrawingProperties.Id);
                ppchart.Name = result[0].NonVisualGraphicFrameProperties.NonVisualDrawingProperties.Name;
                chartList.Add(ppchart);
            }
        }

        return chartList;
    }
