Trace Listeners
in [Dot Net]
|
From: Chris Leffer on 31 Jan 2010 12:18 Hi. How can I dynamically decide which trace listener to use? I tried to use trace switches but it seems that I can't do that with switches. Suppose the configuration file below: <system.diagnostics> <trace autoflush="true"> <listeners> <add name="toFile" type="TextWriterTraceListener" initializeData="App.log" /> <add name="toEvent" type="EventLogTraceListener" initializeData="AppLog" /> </listeners> </trace> </system.diagnostics> Is it possible to redirect the trace output to just one of them during execution?

From: Patrice on 1 Feb 2010 10:10 Hi, Have you tried to you use <clear/> before adding those want ? See : http://msdn.microsoft.com/en-us/library/ms229330.aspx for details... Also it's unclear if you want to keep them both in the config file. If not just comment the one you don't need and your app will use this one else you could lokely change the listeners collection yourself based on your own runtime criteria... Which kind of app is this (Windows, ASP.NET) and what is your preferred programming language ? (in case a code snippet would help understanding the issue). -- Patrice "Chris Leffer" <chrisl(a)wank.com> a �crit dans le message de groupe de discussion : ODePflpoKHA.3948(a)TK2MSFTNGP06.phx.gbl... > Hi. > > How can I dynamically decide which trace listener to use?

From: dotNetDave on 22 Feb 2010 15:44 You can remove a trace listener during runtime via code, but to get it back you would have to restart the app. David ====================================== David McCarter [Microsoft MVP] www.dotNetTips.com David McCarter''''s .NET Coding Standards available at: http://codingstandards.notlong.com "Chris Leffer" wrote: > Hi. > > How can I dynamically decide which trace listener to use?
