Will the helper utility in the reference manual suffice? And if so,
is my "GetAllTags" method the proper way to use it?
Public Function GetAllTags() As IList(Of String)
Dim tags As IList(Of String) = Nothing
Dim session As ISession =
Utility.NHibernateUtil.GetCurrentSession()
Try
tags = session.CreateQuery("select t.Name from Tag t
group by t.Name order by t.Name") _
.List(Of String)()
Finally
Utility.NHibernateUtil.CloseSession()
End Try
Return tags
End Function
Private Const CurrentSessionKey As String =
"nhibernate.current_session"
Private Shared sessionFactory As ISessionFactory
Shared Sub NHibernateUtil()
sessionFactory = New Configuration().Configure
().BuildSessionFactory()
End Sub
Public Shared Function GetCurrentSession() As ISession
Dim currentContext As HttpContext
currentContext = HttpContext.Current
Dim currentSession As ISession = currentContext.Items
(CurrentSessionKey)
If currentSession Is Nothing Then
currentSession = sessionFactory.OpenSession()
currentContext.Items(CurrentSessionKey) =
currentSession
End If
Return currentSession
End Function
Public Shared Sub CloseSession()
Dim currentContext As HttpContext
currentContext = HttpContext.Current
Dim currentSession As ISession = currentContext.Items
(CurrentSessionKey)
If currentSession Is Nothing Then
Return
End If
currentSession.Close()
currentContext.Items.Remove(CurrentSessionKey)
End Sub
Public Shared Sub CloseSessionFactory()
If Not sessionFactory Is Nothing Then
sessionFactory.Close()
End If
End Sub
