如何獲取Excel的單元格的範圍爲循環

Question

我想要獲取for循環中指定的值，然後將它們用作從Excel中獲取單元格的範圍。這裏出了什麼問題？

List<string> str = new List<string>(); 

     // The follwing increments by 4, and starts at 25 

     for (int i = 25; i <= lastRow; i += 4) // += means a + b 
     { 
      str = ws.Range["B"+i].Value; 
     } 

...

SeriesCollection seriesCollection_mySeries = xlChart.SeriesCollection(); 
Series series1 = seriesCollection_mySeries.NewSeries(); 

series1.Values = str 

;

Answer 1

我覺得你的問題應該予以澄清，但是這可能幫助：

for (int i = 25; i <= lastRow; i += 4) // += means a + b 
{ 
    string cellName = "B" + i.ToString(); 
    string cellValue = (string)ws.Range[cellName].Value; 
    str.Add(cellValue); 
}
