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(qǐng)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(duì)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"]) + ";";
