删除/隐藏图例图表excel

嗨,我有以下代码

 private static void exportChart()
    {
        Excel.Range chartRange;
        Excel.ChartObjects xlCharts = (Excel.ChartObjects)oWorkSheet.ChartObjects(Type.Missing);
        Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(10, 80, 300, 150);
        Excel.Chart chartPage = myChart.Chart;

        chartRange = oWorkSheet.get_Range("E5", "F13");
        chartPage.SetSourceData(chartRange, misValue);
        chartPage.ChartType = Excel.XlChartType.xlColumnClustered;

        Excel.Range chartPlacementRange = oWorkSheet.get_Range("F11", "F11");
        myChart.Left = (float)((double)chartPlacementRange.Top);
        myChart.Top = (float)((double)chartPlacementRange.Left);
    }

我试图删除/隐藏图表中的图例,我已经尝试了 this 链接

chart.Legend.LegendEnteries(chart.Legend.LegendEntries().Count).Delete();

所以我的情况是这样的

chartPage.Legend.LegendEntries(chartPage.Legend.LegendEntries().Count).Delete();

但不幸的是,这是我所能做到的。。。。。(键入两次LegendEntries后,它不可用.count或.delete)

chartPage.Legend.LegendEntries(chartPage.Legend.LegendEntries());

如何正确地做?
