Thanks for the replying.
When I say mutliple assemblies I have a GUI app. and it uses log4net to log
to a file let's say 'C:\Claymore.log'.
I have developed several .dll files which I call from within the GUI app. I
want the code within the .dll files to also log to 'C:\Calymore.log'.
I've actually just managed to get it working but I'm not using locking and
wonder whether I should be or not for this scenario. As far as I'm aware
everything will run in the same process and should be fine without
locking......?
Here's what I've done:
In both the GUI front-end and each .dll I have added the following entry to
the AssemblyInfo.vb (yes, I'm using vb.net!) file
<Assembly:
log4net.Config.XMLConfigurator(ConfigFile:="Claymore.exe.log4net",
Watch:=True)>
In GUI Front-End Assembly ONLY I've added 'Claymore.exe.log4net' file.
Then in GUI Front-End class:
Public Class frmDashboard
Public Shared logger As log4net.ILog
Private Sub frmDashboard_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
log4net.GlobalContext.Properties("AssemblyName") =
Assembly.GetExecutingAssembly.GetName.Name()
logger = log4net.LogManager.GetLogger("ClaymoreLogger")
logger.Info("Dashboard_Load() - Start")
logger.Debug("Dashboard_Load() - Finish")
Dim clsGUI As New ClaymoreGUI.clsDashboard()
End Sub
End Class
In my ClaymoreGUI.dll:
Public Class clsDashboard
Public Shared logger As log4net.ILog
Public Sub New()
log4net.GlobalContext.Properties("AssemblyName") =
Assembly.GetExecutingAssembly.GetName.Name()
logger = log4net.LogManager.GetLogger("ClaymoreLogger")
logger.Info("New() - Start")
logger.Debug("New() - Finish")
End Sub
End Class
Seems to work well :-)
