我使用Excel 2010中我想这样救我的Excel文件,与此代码。 它保存一个.xls文件,但是当我打开该文件,我得到这个消息:
你试图打开,“tre.xls”的文件,是在不同的格式由文件扩展名指定。 验证该文件没有损坏,是从逆冲源打开文件之前。 你现在要打开的文件?
如果我按yes
打开该文件。 但是,我需要摆脱这种格式弹出的?
我的代码:
using System;
using System.Windows.Forms;
using ExcelAddIn1.Classes;
using ExcelAddIn1.Classes.Config;
using Microsoft.Office.Interop.Excel;
using Application = Microsoft.Office.Interop.Excel.Application;
using System.Runtime.InteropServices;
private void Foo(object sender, EventArgs e)
{
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "Execl files (*.xls)|*.xls";
saveFileDialog.FilterIndex = 0;
saveFileDialog.RestoreDirectory = true;
saveFileDialog.CreatePrompt = true;
saveFileDialog.FileName = null;
saveFileDialog.Title = "Save path of the file to be exported";
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
// Save.
// The selected path can be got with saveFileDialog.FileName.ToString()
Application excelObj =
(Application)Marshal.GetActiveObject("Excel.Application");
Workbook wbook = excelObj.ActiveWorkbook;
wbook.SaveAs(saveFileDialog.FileName, XlFileFormat.xlWorkbookDefault,
Type.Missing, Type.Missing, false, false,
XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing);
wbook.Close();
}
}
当我在Excel中保存在正常的方式,我得到“Book1.xlsx”,那也没问题打开。
=============最终解决============
private void Foo(object sender, EventArgs e)
{
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "Execl files (*.xls)|*.xls";
saveFileDialog.FilterIndex = 0;
saveFileDialog.RestoreDirectory = true;
saveFileDialog.CreatePrompt = true;
saveFileDialog.FileName = null;
saveFileDialog.Title = "Save path of the file to be exported";
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
Application excelObj = (Application)Marshal.GetActiveObject("Excel.Application");
Activate(); // <-- added (recommend by msdn, but maybe not nessary here)
Workbook wbook = excelObj.ActiveWorkbook;
wbook.SaveAs(saveFileDialog.FileName, XlFileFormat.xlExcel8, Type.Missing,
Type.Missing, false, false, XlSaveAsAccessMode.xlNoChange, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing);
// wbook.Close(); // <-- don't want this anymore
}
}
