如何創建和使用C＃編寫Excel .xls文件

Question

我有幾個測試運行三次，並有平均通過C＃代碼計算。我能夠寫入三個測試時間，並有平均的xls文件，如果創建之前在下面的圖片格式。但是現在我必須每天通過使用Windows調度程序的批處理文件運行每個測試。我想在下面提到的格式中每小時動態地創建xls文件，並使用特定名稱，以便在第一次迭代時創建文件，並且對於接下來的19次迭代，它應該在同一個文件中寫入，然後在下一小時內使用特定名稱。如何動態創建和寫入excel文件？ 如果還有其他簡單的程序請參考。我是用寫在已創建的XLS文件的代碼是：`/ *

有一種方法來處理這個使用數據網格。

下面的示例接受一個DataSet（您可以傳遞一個列表或表）。

然後在FLY上創建一個GridView並將其導出到Excel。我在很多網站上使用這種方法。

public static void ExportDataSetToExcel(DataSet ds, string filename) 
{ 
    try 
    { 
     HttpResponse response = HttpContext.Current.Response; 

     // first let's clean up the response.object 
     response.Clear(); 
     response.Charset = ""; 

     // set the response mime type for excel 
     response.ContentType = "application/vnd.ms-excel"; 
     response.AddHeader("Content-Disposition", "attachment;filename=\"" + filename + "\""); 

     // create a string writer 
     using (StringWriter sw = new StringWriter()) 
     { 
      using (HtmlTextWriter htw = new HtmlTextWriter(sw)) 
      { 
       // instantiate a datagrid 
       DataGrid dg = new DataGrid(); 
       dg.DataSource = ds; 
       dg.DataBind(); 
       dg.RenderControl(htw); 
       response.Write(sw.ToString()); 
       response.End(); 
      } 
     } 
    } 
    catch { } 
}

在所有誠實，你可能會更好使用CSV文件，這種方式從你ranorex的測試，你可以簡單地使用有System.IO.File寫入輸出文本文件，以及有關的好處csv格式是可以打開的excel
