如何在没有安装MS Office的计算机上使用Microsoft.Office.Interop.Excel？

Question

我正在编写一个与excel文件一起使用的应用程序.我需要一个删除工作表的功能.我必须使用程序集Microsoft.Office.Interop.Excel.dll.

它在开发人员计算机上运行良好,但当我尝试在服务器上部署它时,我收到一个错误:

无法加载文件或程序集'office,Version = 14.0.0.0,Culture = neutral,PublicKeyToken = 71e9bce111e9429c'或其中一个依赖项

我知道在计算机上未安装MS Office时会出现问题.客户不希望以任何价格在服务器上安装和购买MS Office.

我按照此处的建议在开发人员计算机上安装"Redistributable Primary Interop Assemblies":http://forums.asp.net/t/1530230.aspx/1 并再次编译我的项目.

代码示例:

public bool DeleteSheet(string tableName)
{
    Excel.Application app = null;
    Excel.Workbooks wbks = null;
    Excel._Workbook _wbk = null;
    Excel.Sheets shs = null;

    bool found = false;

    try
    {
        app = new Excel.Application();
        app.Visible = false;
        app.DisplayAlerts = false;
        app.AlertBeforeOverwriting = false;

        wbks = app.Workbooks;
        _wbk = wbks.Add(xlsfile);
        shs = _wbk.Sheets;
        int nSheets = shs.Count;

        for (int i = 1; i <= nSheets; i++)
        {
            Excel._Worksheet _iSheet = (Excel._Worksheet)shs.get_Item(i);
            if (_iSheet.Name == tableName)
            {
                _iSheet.Delete();
                found = true;

                Marshal.ReleaseComObject(_iSheet);
                break;
            }
            Marshal.ReleaseComObject(_iSheet);
        }

        if (!found)
            throw new Exception(string.Format("Table \"{0}\" was't found", tableName));

        _wbk.SaveAs(connect, _wbk.FileFormat, Missing.Value, Missing.Value, Missing.Value,
        Missing.Value, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
        Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);
    }
    finally
    {
        _wbk.Close(null, null, null);
        wbks.Close();
        app.Quit();

        Marshal.ReleaseComObject(shs);
        Marshal.ReleaseComObject(_wbk);
        Marshal.ReleaseComObject(wbks);
        Marshal.ReleaseComObject(app);
    }
    return true;
}

例外

由于以下错误,检索CLSID为{00024500-0000-0000-C000-000000000046}的组件的COM类工厂失败:80040154未注册类(HRESULT异常:0x80040154(REGDB_E_CLASSNOTREG)).

app = new Excel.Application();

任何人都可以建议如何使这项功能成功运作？

如果没有安装ms office,则无法使用Microsoft.Office.Interop.Excel.

只需在谷歌搜索一些库,允许修改xls或xlsx:

• http://code.google.com/p/excellibrary/
• http://simpleooxml.codeplex.com/(仅限xlsx)
