我有一个小应用程序,最后用户可以将结果保存在excel文件中。一切看起来都不错,但在此之后几秒钟微软Windows通信:“程序Microsoft Office Excel停止工作”。好的 - 加入它。
如果用户将数据保存为* .xls文件,则打开此文件没有问题 - 保存到此文件中的数据是正确的。
如果用户将数据保存为* .xlsx文件,则会出现问题。当我尝试打开此文件时,显示消息:“程序Microsoft Excel无法打开文件* .xlsx,因为文件格式或扩展名有误。检查文件是否已损坏,文件扩展名是否与其格式正确”
我用来将数据保存为excel文件的代码如下:
public void SaveData(ExcelWriter ew)
{
SaveFileDialog saveFD = new SaveFileDialog();
saveFD.InitialDirectory = "C:\\users\\Documents";
saveFD.FileName = this._saveExcelFileName;
saveFD.Filter = "excel 97-03(*.xls)|*.xls|excel 2007 (*.xlsx)|*.xlsx";
saveFD.FilterIndex = 2;
saveFD.RestoreDirectory = true;
if (saveFD.ShowDialog() == DialogResult.OK)
{
try
{
this._saveExcelFileName = saveFD.FileName;
ew.RunExcelWriter(_dt, _saveExcelFileName);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
public void RunExcelWriter(DataTable DataT, string fileName)
{
StartExcel();
GetANewWorkbook();
GetTheActiveSheet();
ProcessTheDataTable(DataT);
SaveTheSheet(fileName);
Clean();
}
private void StartExcel()
{
// Start Excel and get Application object.
oXL = new Excel.Application();
// Set some properties
oXL.Visible = true;
oXL.DisplayAlerts = false;
}
private void GetANewWorkbook()
{
// Get a new workbook.
oWB = oXL.Workbooks.Add(Missing.Value);
}
private void GetTheActiveSheet()
{
oSheet = (Excel.Worksheet)oWB.ActiveSheet;
oSheet.Name= "Wyniki";
}
private void ProcessTheDataTable(DataTable DT)
{
int rowCount = 1;
foreach (DataRow dr in DT.Rows)
{
rowCount += 1;
for (int i = 1; i < DT.Columns.Count + 1; i++)
{
// Add the header the first time through
if (rowCount == 2)
{
oSheet.Cells[1, i] = DT.Columns[i - 1].ColumnName;
}
oSheet.Cells[rowCount, i] = dr[i - 1].ToString();
}
}
// Resize the columns
oRange = oSheet.get_Range(oSheet.Cells[1, 1], oSheet.Cells[rowCount, DT.Columns.Count]);
oRange.EntireColumn.AutoFit();
//oRange.Style = oSheet.Cells.Style;
}
private void SaveTheSheet(string FN)
{
oSheet = null;
oRange = null;
oWB.SaveAs(FN, Excel.XlFileFormat.xlWorkbookNormal,
Missing.Value, Missing.Value, Missing.Value, Missing.Value,
Excel.XlSaveAsAccessMode.xlShared,
Missing.Value, Missing.Value, Missing.Value,
Missing.Value, Missing.Value);
if(oWB.Saved==true)
{
MessageBox.Show("Plik został zapisany pomyślnie");
}
else
{
MessageBox.Show("PLIKU NIE ZAPISANO");
}
oWB.Close(Missing.Value, Missing.Value, Missing.Value);
oWB = null;
oXL.Quit();
}
如果有人知道为什么会这样? 非常感谢提前
建议的答案不起作用。我改为:
private void SaveTheSheet(string FN)
{
oSheet = null;
oRange = null;
oWB.SaveAs(FN, Excel.XlFileFormat.xlXMLSpreadsheet,
Missing.Value, Missing.Value, Missing.Value, Missing.Value,
Excel.XlSaveAsAccessMode.xlShared,
Missing.Value, Missing.Value, Missing.Value,
Missing.Value, Missing.Value);
if(oWB.Saved==true)
{
MessageBox.Show("Plik został zapisany pomyślnie");
}
else
{
MessageBox.Show("PLIKU NIE ZAPISANO");
}
oWB.Close(Missing.Value, Missing.Value, Missing.Value);
oWB = null;
oXL.Quit();
}
现在,当我保存时,有一个meesage:
“HRESULT异常:0x800A03EC
昨天我有点挣扎,在将数据写入.xlsx格式时,我设法获得了预期的效果。保存到.xls时,我仍然收到Microsoft Windows消息以关闭excel应用程序,但至少(在另一个警告批准后)我可以打开此文件。 下面我用来保存为.xlsx格式的代码:
oWB.SaveAs(FN, Excel.XlFileFormat.xlWorkbookDefault,
Missing.Value, Missing.Value, false, false,
Excel.XlSaveAsAccessMode.xlNoChange,
Missing.Value, Missing.Value, Missing.Value,
Missing.Value, Missing.Value);
这是.xls
oWB.SaveAs(FN, Excel.XlFileFormat.xlXMLSpreadsheet,
Missing.Value, Missing.Value, Missing.Value, Missing.Value,
Excel.XlSaveAsAccessMode.xlNoChange,
Missing.Value, Missing.Value, Missing.Value,
Missing.Value, Missing.Value);
请 - 任何建议都很重要。
答案 0 :(得分:2)
就我而言,aslo作品Excel.XlFileFormat.xlWorkbookDefault
和Excel.XlFileFormat.xlOpenXMLWorkbook
oWB.SaveAs(fileName, Excel.XlFileFormat.xlOpenXMLWorkbook, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
或
oWB.SaveAs(fileName, Excel.XlFileFormat.xlWorkbookDefault, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
答案 1 :(得分:0)
保存为.xslx时,请尝试使用Excel.xlXMLSpreadsheet而不是Excel.XlFileFormat.xlWorkbookNormal
