EntLib 5 Changing logging location at runtime

Is there another way to change the logging location of Logging block of entlib? Currently i have the following code to do the change

开发者_运维知识库     var location = CommonConfiguration.ErrorLogPath;
        ConfigurationFileMap configFileMap = new ConfigurationFileMap();
        configFileMap.MachineConfigFilename = "AppName.exe.config";
        var entLibConfig = ConfigurationManager.OpenExeConfiguration(System.Configuration.ConfigurationUserLevel.None);
        LoggingSettings loggingSettings = (LoggingSettings)entLibConfig.GetSection(LoggingSettings.SectionName);
        RollingFlatFileTraceListenerData fileTraceListener = loggingSettings.TraceListeners.Get("Rolling Flat File Trace Listener") as RollingFlatFileTraceListenerData;
        fileTraceListener.FileName = Path.Combine(location, @"Log\Appname.log");
        entLibConfig.Save();

the issue with this is that when users don't have write access the change isn't being saved to the logging file

You may use Using the Fluent Configuration API,like following unit test code:

     [Test]   
     public void TestLoggingWithFluentConfigurationAPI()   
     {  
         var builder = new ConfigurationSourceBuilder();   
         builder.ConfigureLogging()  
             .WithOptions  
             .DoNotRevertImpersonation()  
             .LogToCategoryNamed("Basic")  
             .SendTo.FlatFile("Basic Log File")  
             .FormatWith(new FormatterBuilder()  
                             .TextFormatterNamed("Text Formatter")  
                             .UsingTemplate(  
                                 "Timestamp: {timestamp}{newline Message: {message}{newline}Category: {category}{newline}"))  
             .ToFile("d:\\logs\\BasicTest.log") 
             .SendTo.RollingFile("Rolling Log files") 
             .RollAfterSize(1024)  
             .ToFile("d:\\logs\\RollingTest.log")  
              .LogToCategoryNamed("General")  
      .WithOptions.SetAsDefaultCategory()  
      .SendTo.SharedListenerNamed("Basic Log File");  

         var configSource = new DictionaryConfigurationSource(); 
         builder.UpdateConfigurationWithReplace(configSource);  

         EnterpriseLibraryContainer.Current  
           = EnterpriseLibraryContainer.CreateDefaultContainer(configSource); 
         LogWriterFactory logFactory = new LogWriterFactory(configSource);  
         LogWriter logWriter = logFactory.CreateDefault();  
         logWriter.Write("This is test message", "Basic");  
         logWriter.Write("This is default message");  

         string logfilepath = Path.Combine("d:", "logs\\BasicTest.log");  
         Assert.IsTrue(File.Exists(logfilepath)); 
         Assert.IsTrue(File.Exists("d:\\logs\\RollingTest.log"));

     }
