<appSettings> <add key="sDBConnectionString" value="Provider=Microsoft.Jet.OLEDB.4.0;datasource=C:\excelsior\.Net Applications\TDAPP8-Web_Based_Bug_tracking_system\Web based Bug Tracking SystemAccessDB.mdb"/> </appSettings>

Answer 1

找不到可安装的ISAM是错误的连接字符串的典型代表。

"Provider=Microsoft.Jet.OLEDB.4.0;data source=C:\excelsior\.Net Applications\TDAPP8-Web_Based_Bug_tracking_system\Web based Bug Tracking SystemAccessDB.mdb"

注意数据源带有空格。
