2007数据库
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Database1.accdb");
2003数据库
con=new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\"数据库.mdb\";Jet OLEDB:Database Password=aking");
********************
private static void openConnection()
{
if (conn.State == ConnectionState.Closed )
{
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="
+ System.Web.HttpContext.Current.Server.MapPath(ConfigurationManager.ConnectionStrings["DbPath"].ToString());
comm.Connection = conn;
try
{
conn.Open();
}
catch (Exception e)
{
throw new Exception(e.Message);
}
}
}
<connectionStrings>
<add name="DBPath" connectionString="~/App_Data/Web.mdb"/>
<!--数据库路径，前面的~必须保留-->
</connectionStrings>
改为ACCESS后怎么写呢?
<connectionStrings>
<add name="DBPath" connectionString="~/App_Data/Web.mdb"/>
<!--数据库路径，前面的~必须保留-->
</connectionStrings>
private static void openConnection()
{
if (conn.State == ConnectionState.Closed )
{
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="
+ System.Web.HttpContext.Current.Server.MapPath(ConfigurationManager.ConnectionStrings["DbPath"].ToString());
comm.Connection = conn;
try
{
conn.Open();
}
catch (Exception e)
{
throw new Exception(e.Message);
}
}
}
这两个 加一块 就行了,前面 那个 在web.config中写
<appSettings>
<add key="OLEDBCONNECTIONSTRING" value="provider=microsoft.jet.oledb.4.0;data source="/>
<add key="dbPath" value="~/App_Data/Data.mdb"/>
</appSettings>
***********************************************
public static OleDbConnection CreateDB()
{
return new OleDbConnection(ConfigurationManager.AppSettings["OLEDBCONNECTIONSTRING"].ToString() + System.Web.HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings["dbPath"]));
}
