Excel.ApplicationClass excel=new Excel.ApplicationClass();
excel.Application.Workbooks.Open(@"E:\MFGP\ar20061220.xls",new object[]{3} ,new object[]{false},new object[]{5},new object[]{""},new object[]{""},new object[]{false},Excel.XlPlatform.xlWindows,null,new object[]{false},new object[]{true},Excel.XlFileFormat.xlExcel9795,new object[]{true},new object[]{true},new object[]{true});
range=(Excel.Range)excel.Cells[1,2];
Messagebox.Show(range.Value2.ToString());
为什么读出来是一个数值，如2008-08-08读出来是39688，怎样才能读出来是日期格式。
