asp.net連接access數(shù)據(jù)庫路徑問題

    解決方案一：
    在 Web.Config 中配置 Access 數(shù)據(jù)庫教程驅(qū)動(dòng)和數(shù)據(jù)庫文件名稱。
    請看代碼
    <appSettings>
    <add key="DBDriver" value="Provider=Microsoft.Jet.OLEDB.4.0; Data Source ="/>
    <add key="DBName" value="Company.mdb"/>
    </appSettings>
    在數(shù)據(jù)庫訪問層，如 OleDBHelper.cs 中獲得 Access 數(shù)據(jù)庫鏈接字符串。
    /**//// <summary>
    /// 從Web.Config取得數(shù)據(jù)庫聯(lián)接字符串
    /// </summary>
    //從配置文件中得到數(shù)據(jù)庫名稱
    public static readonly string DBName = ConfigurationManager.AppSettings.Get("DBName").ToString();
    //從配置文件中得到數(shù)據(jù)庫驅(qū)動(dòng)
    public static readonly string DBDriver = ConfigurationManager.AppSettings.Get("DBDriver").ToString();
    //得到數(shù)據(jù)庫連接字符串
    private static string DBConnectionString = DBDriver + HttpContext.Current.Server.MapPath(HttpContext.Current.Request.ApplicationPath + "/App_Data/") + DBName;
    //建立數(shù)據(jù)庫連接對象
    private static OleDbConnection OleDbConn = new OleDbConnection(DBConnectionString);
    這樣設(shè)置后，無論在任何子目錄，都能通過以上代碼正確的訪問數(shù)據(jù)庫。
    解決方案二：
    <appSettings>
    <add key="SQLConnString" value="provider=microsoft.jet.oledb.4.0;data source="/>
    <add key="dbPath" value="~/App_Data/mydata.mdb"/>
    </appSettings>
    程序中的數(shù)據(jù)訪問類中我把"SQLConnString"和"dbPath"取出來連接成一個(gè)字符串"CONN_STRING_NON_DTC"
    public static readonly string CONN_STRING_NON_DTC = System.Configuration.ConfigurationManager.AppSettings["SQLConnString"].ToString() + System.Web.HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings["dbPath"]) + ";";
