为什么我访问access数据库的时候经常会连接失败啊。我的连接串是写在web.config里面的
<add key="myds" value="Provider=Microsoft.Jet.OLEDB.4.0;Data source="/>
<add key="myconn" value="\App_Data\WaterDB.mdb"/>
代码如下：
public static readonly string ConnectionString = ConfigurationManager.AppSettings["myds"] +HttpContext.Current.Server.MapPath("~")+ (ConfigurationManager.AppSettings["myconn"].Trim());
C# code:
<connectionStrings>
<add name="ydycon" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=|DataDirectory|WaterDB.mdb" providerName="System.Data.OleDb"/>
</connectionStrings>
C# code:
string conn=System.Configuration .ConfigurationManager.ConnectionStrings ["ydycon"].ToString()
配置文件如下
<add key="Connectionstring" value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source="/>
<add key="dbPath" value="~/App_Data/testdb.mdb"/>
