使用C＃dynamic添加范围值到Excel图表

我正在尝试使用C＃.net生成幻灯片幻灯片的图表。 当我对数据进行硬编码时，图表完美地工作，所以我的目标是能够从我的应用程序数据表中填充excel后端。 我需要帮助的是定义数据范围（见下文）

var areaworkbook = (EXCEL.Workbook)areachart.ChartData.Workbook; areaworkbook.Windows.Application.Visible = false; var dataSheet2 = (EXCEL.Worksheet)areaworkbook.Worksheets[1]; var sc2 = areachart.SeriesCollection(); dataSheet1.Cells.Range["A2"].Value2 = "Name 1"; dataSheet1.Cells.Range["A3"].Value2 = "Name 2"; dataSheet1.Cells.Range["A4"].Value2 = "Name 3"; dataSheet1.Cells.Range["A5"].Value2 = "Name 4"; dataSheet1.Cells.Range["B2"].Value2 = Value 1; dataSheet1.Cells.Range["B3"].Value2 = value 2; dataSheet1.Cells.Range["B4"].Value2 = value 3; dataSheet1.Cells.Range["B5"].Value2 = value 4 ; var series2 = sc2.NewSeries(); series2.Name = "Series 2"; series2.XValues = "'Sheet1'!$A$2:$A$5"; series2.Values = "'Sheet1'!$C$2:$C$5"; series2.ChartType = Office.XlChartType.xlAreaStacked; areachart.HasTitle = true; areachart.ChartTitle.Font.Bold = true; areachart.ChartTitle.Font.Italic = true; areachart.ApplyLayout(4); areachart.Refresh(); 

我将如何dynamic添加A6，A7，A8 …直到我的数据表完成？

只需使用一个循环并计算单元地址。 为了争辩，我将假定数据来自Linq查询，尽pipe您可以通过其他方式获得。

 int row = 2; // You expect to start here foreach (var data in db.MyData().Where(... whatever you need here ...)) { dataSheet1.Cells.Range["A" + row].Value2 = data.Name; dataSheet1.Cells.Range["B" + row].Value2 = data.Value; row++; } series2.XValues = "'Sheet1'!$A$2:$A$" + row; series2.Values = "'Sheet1'!$C$2:$C$" + row;
