如何使用 C# 和 Interop 设置图表标题?
实际尝试:
Excel.Range chartRange;
Excel.ChartObjects xlCharts = (Excel.ChartObjects)xlsSheet.ChartObjects(Type.Missing);
Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(10, 80, 300, 250);
Excel.Chart chartPage = myChart.Chart;
chartRange = xlsSheet.Range[xlsSheet.Cells[1, 1], xlsSheet.Cells[ar.GetLength(0), ar.GetLength(1)]];
chartPage.SetSourceData(chartRange, Excel.XlRowCol.xlRows);
chartPage.ChartType = Excel.XlChartType.xl3DColumn;
chartPage.Location(Excel.XlChartLocation.xlLocationAsNewSheet, oOpt);
chartPage.HasTitle = true;
chartPage.ChartTitle.Text = "HeaderText";
