我的客户希望他们的价目表出现在他们的网站上。我正在尝试使用电子表格 (.xlsx) 作为数据源，以便在数据出现在网站上之前限制数据的处理。
该站点在 IIS 7 上运行。服务器是 Windows Server 2008。我已将其上的 .NET Framework 更新为 4.0。
它没有安装任何 Office 软件包，我有一种预感，那就是我的问题所在，但我真的很想确定。
这是我得到的错误文本：
System.InvalidOperationException: The 'Microsoft.Jet.OLEDB.4.0' 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.ProviderBase.DbConnectionFactory.CreateNonPooledConnection(DbConnection owningConnection, DbConnectionPoolGroup poolGroup) at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.OleDb.OleDbConnection.Open() at Products.Page_Load(Object sender, EventArgs e) in C:\HostingSpaces\webbuddies\waterinc.webbuddies.co.za\wwwroot\Products.aspx.vb:line 14
这是我的代码：

自发布以来，我已经从第一个答案中的链接在服务器上安装了 2007 办公驱动程序，并且我根据第二个答案修改了我的连接字符串：
<connectionStrings>
<add name="xlsx" connectionString="Provider=Microsoft.ACE.OLEDB.12.0; Data Source=App_Data/Pricelist.xlsx; Extended Properties=Excel 12.0 Xml; HDR=YES;"/>
</connectionStrings>
