我想使用Microsoft.Office.Interop.Excel dll將數據寫入Excel工作表。我有一個代碼:如何使用Microsoft.Office.Interop.Excel dll以編程方式打開excel來編寫excel?
if (System.IO.File.Exists(strFileName))
{
System.IO.File.SetAttributes(strFileName, FileAttributes.Normal);
System.IO.File.Delete(strFileName);
}
// Open an instance of excel. Create a new workbook.
// A workbook by default has three sheets, so if you just want
//a single one, delete sheet 2 and 3
Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
Excel._Workbook xlWB = (Excel._Workbook)xlApp.Workbooks.Add(Missing.Value);
Excel._Worksheet xlSheet = (Excel._Worksheet)xlWB.Sheets[1];
((Excel._Worksheet)xlWB.Sheets[2]).Delete();
((Excel._Worksheet)xlWB.Sheets[2]).Delete();
xlSheet.Name = strSheetName;
// Write a value into A1
xlSheet.Cells[2, 1] = "Tags";
xlSheet.Cells[2, 2] = "Leak Test";
xlSheet.Cells[2, 3] = "FIR";
xlSheet.Cells[2, 4] = "SOP";
xlWB.SaveAs(strFileName, Missing.Value, Missing.Value, Missing.Value,
Missing.Value,Missing.Value,
Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, Missing.Value,
Missing.Value, Missing.Value, Missing.Value, Missing.Value);
xlApp.Quit();
// Release the COM object, set the Excel variables to Null, and tell the
//Garbage Collector to do its thing
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlSheet);
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlWB);
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);
xlSheet = null;
xlWB = null;
xlApp = null;
現在我想打開現有的路徑& excel文件,然後把一些數據,我們提供姓名&那麼它將從程序保存到特定路徑上的Excel工作表。
請回復我的源代碼,如果有任何可以打開現有的Excel文件&,可以追加&另存爲另一個名稱。
問候, 吉里什
你的意思是限於Excel XLSX,XLSM和XLST格式和更新的不是嗎? – 2010-09-10 04:26:43
@匿名類型:是,2007和2010 OpenXML格式 - ExcelPackage支持這些格式。它不支持Excel 2003及更早版本使用的較舊的未公開的二進制XLS格式。 – 2010-09-10 04:52:38
