C# .net web.config配置access连接字符串

<appSettings>

<add key="AccessConnString" value="provider=microsoft.jet.oledb.4.0;datasource="/>

<add key="DbPath" value="~/App_Data/Test .mdb"/>

</appSettings>

在c#代码中创建OleDbConnection 连接，通过MapPath取得服务器上的物理路径：

private static OleDbConnection conn = new OleDbConnection(System.Configuration.ConfigurationManager.AppSettings["AccessConnString"].ToString() + System.Web.HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings["DbPath"]) + ";");
