asp.net連接access數(shù)據(jù)庫路徑問題

　　解決方案一 

　　在 WebConfig 中配置 Access 數(shù)據(jù)庫教程驅(qū)動和數(shù)據(jù)庫文件名稱 
請看代碼

<appSettings> 
<add key="DBDriver" value="Provider=MicrosoftJetOLEDB; Data Source ="/> 
<add key="DBName" value="Companymdb"/> 
</appSettings> 

　　在數(shù)據(jù)庫訪問層如 OleDBHelpercs 中獲得 Access 數(shù)據(jù)庫鏈接字符串

/**//// <summary> 
/// 從WebConfig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 = ConfigurationManagerAppSettingsGet("DBName")ToString(); 
//從配置文件中得到數(shù)據(jù)庫驅(qū)動 
public static readonly string DBDriver = ConfigurationManagerAppSettingsGet("DBDriver")ToString(); 
//得到數(shù)據(jù)庫連接字符串 
private static string DBConnectionString = DBDriver + HttpContextCurrentServerMapPath(HttpContextCurrentRequestApplicationPath + "/App_Data/") + DBName; 
//建立數(shù)據(jù)庫連接對象 
private static OleDbConnection OleDbConn = new OleDbConnection(DBConnectionString); 

　　這樣設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=microsoftjetoledb;data source="/>
<add key="dbPath" value="~/App_Data/mydatamdb"/>
</appSettings>

　　程序中的數(shù)據(jù)訪問類中我把"SQLConnString"和"dbPath"取出來連接成一個字符串"CONN_STRING_NON_DTC"

public static readonly string CONN_STRING_NON_DTC = SystemConfigurationConfigurationManagerAppSettings["SQLConnString"]ToString() + SystemWebHttpContextCurrentServerMapPath(ConfigurationManagerAppSettings["dbPath"]) + ";";
