將程式碼部署到測試機器上，因為使用了OLEDB操作Excel，程式出現如下錯誤：
System.InvalidOperationException: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.
at System.Data.OleDb.OleDbServicesWrapper.GetDataSource(OleDbConnectionString constr, DataSourceWrapper& datasrcWrapper)
at System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection)
at System.Data.OleDb.OleDbConnectionFactory.CreateConnection(DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject)

at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet)
其中，連線程式碼如下：
?| 1 |
Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Excel 12.0 Xml;HDR=YES;
|
出現以上錯誤後，先安裝一個元件，如果不行再設定IIS即可。
因為伺服器上未安裝Microsoft office，所以從官網上下載了一個包：AccessDatabaseEngine.exe
相關說明：
This download will install a set of components that facilitate the transfer of data between existing Microsoft Office files such as Microsoft Office Access 2007 (*.mdb and *.accdb) files and Microsoft Office Excel 2007 (*.xls, *.xlsx, and *.xlsb) files to other data sources such as Microsoft SQL Server. Connectivity to existing text files is also supported.
安裝完成後，還需要在IIS連線池配置一個屬性即可：
開啟IIS-->找到與網站相對應的應用程式池-->高階設定-->常規-->啟用32位應用程式的值為：True即可。
