XPO中的Session实例和创建Access数据库

创建Access数据库(文件名为:Data.MDF 密码为:123456)
String connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password=123456;Data Source=c://Data.MDF;";
ADOX.CatalogClass CreateADOX = new CatalogClass();
CreateADOX.Create(connectionString);

第一:
String connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password=123456;Data Source=c://Data.MDF;";
IDataLayer dataLayer = XpoDefault.GetDataLayer(connectionString, AutoCreateOption.DatabaseAndSchema);
Session retSession = new Session(dataLayer);
if (!retSession.IsConnected)
{ retSession.Connect(); }

第二:
string connectionString = MSSqlConnectionProvider.GetConnectionString(开发库配置.Host, 开发库配置.UserName, 开发库配置.PassWord, 开发库配置.Database);
IDataLayer dataLayer = XpoDefault.GetDataLayer(connectionString, AutoCreateOption.DatabaseAndSchema);
XpoDefault.DataLayer = dataLayer;
Session retSession = XpoDefault.Session;
if (!retSession.IsConnected)
{ retSession.Connect(); }

第三:
String connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password=123456;Data Source=c://Data.MDF;";
IDataLayer dataLayer = XpoDefault.GetDataLayer(connectionString, AutoCreateOption.DatabaseAndSchema);
XpoDefault.DataLayer = dataLayer;
Session retSession = XpoDefault.Session;
if (!retSession.IsConnected)
{ retSession.Connect(); }
