在我的应用程序中，我必须阅读OpenOffice电子表格并在网格视图中显示电子表格中的数据是我使用的代码，但是它提供了一个例外，即外部表格格式不正确我如何解决这个问题

 <div>
        Import Excel File:  
        <asp:FileUpload ID="FileUpload1" runat="server" />  
        <br />

    </div>  

 //Coneection String by default empty  
            string ConStr = "";
            //Extantion of the file upload control saving into ext because   
            //there are two types of extation .xls and .xlsx of Excel

            //getting the path of the file   
            string path = Server.MapPath("~/MyFolder/" + FileUpload1.FileName);
            //saving the file inside the MyFolder of the server  
            FileUpload1.SaveAs(path);
            Label1.Text = FileUpload1.FileName + "\'s Data showing into the GridView";
            //checking that extantion is .xls or .xlsx  
            if (ext.Trim() == ".ods")
            {
                //connection string for that file which extantion is .xls  
                ConStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";

            //making query  
            string query = "SELECT * FROM [Sheet1$]";
            //Providing connection  
            OleDbConnection conn = new OleDbConnection(ConStr);
            //checking that connection state is closed or not if closed the   
            //open the connection  
            if (conn.State == ConnectionState.Closed)
            {
                conn.Open();
            }
            //create command object  
            OleDbCommand cmd = new OleDbCommand(query, conn);
            // create a data adapter and get the data into dataadapter  
            OleDbDataAdapter da = new OleDbDataAdapter(cmd);
            DataSet ds = new DataSet();
            //fill the Excel data to data set  
            da.Fill(ds);
            //set data source of the grid view  
            gvExcelFile.DataSource = ds.Tables[0];
            //binding the gridview  
            gvExcelFile.DataBind();
            //close the connection  
            conn.Close();

ActiveXObject仅适用于Internet Explorer，如here所述。

对于其他浏览器，Silverlight可以AutomationFactory执行此操作。但是，由于涉及安全风险，我没有尝试过。

另一种方法是将ReadExcel()函数放在以.js结尾的文件中，然后在文件末尾添加行ReadExcel();。将excelFile设置为电子表格文件的路径。我双击运行它，然后它成功加载了OpenOffice文档。

修改：

查看以下行是否导致相同的错误：

var objShell = new ActiveXObject("WScript.shell");

如果是，那么问题与OpenOffice或您的代码无关。也许您需要授予Internet Explorer不安全的运行权限。请参阅https://social.technet.microsoft.com/Forums/ie/en-US/8db7ec28-45ca-4859-b051-f0571a4da14e/error-automation-server-cant-create-object?forum=ieitpropriorver。
