我正在使用oledb连接将Excel工作表导入DataTable,如下所示.

private static DataTable UploadExcelSheet(string fileName)
    {
        DataTable uploadDataTable;
        using (OleDbConnection objXConn = new OleDbConnection())
        {
            objXConn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName +
                                            ";Extended Properties=\"Excel 12.0;IMEX=1\"";

            objXConn.Open();

            OleDbCommand objCommand =
                new OleDbCommand("SELECT * FROM Template$ ", objXConn);
            OleDbDataAdapter objDataAdapter = new OleDbDataAdapter();

            // retrieve the Select command for the Spreadsheet
            objDataAdapter.SelectCommand = objCommand;

            // Create a DataSet
            DataSet objDataSet = new DataSet();

            // Populate the DataSet with the spreadsheet worksheet data
            objDataAdapter.Fill(objDataSet);
            uploadDataTable = objDataSet.Tables[0];
        }

        return uploadDataTable;
    }

一切都运行正常,但是当用户在上传excel之前删除几行内容时会出现问题.它还会读取这些空行以及非空行,并且由于业务规则违规(缺少必填字段),因此在数据库中保存数据失败.我尝试的是在查询中放置条件: …
