使用C＃动态添加范围值以优化图表＃

Question

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。我需要什么是定义数据范围帮助（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(); 

我将如何动态地添加A6，A7，A8 ......直到我的数据表是否已经完成？

Answer 1

只需使用一个循环并计算单元地址。为了争辩，我将假设数据来自Linq查询，尽管您可以通过任何其他方式得到它。

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;
