構成ファイルではなく、コードで動的なローリング アペンダーを設定したいと考えています。だから私は log4net.ILog を返す関数を持っています
<Assembly: log4net.config.XmlConfigurator(ConfigFile:="Log4Net.config", Watch:=True)>
Public Function genLogXMLCfg(cls As Object) As log4net.ILog
Dim clsName As String = cls.ToString()
Dim rollAppen As New RollingFileAppender()
rollAppen.Name = clsName + "Appender"
rollAppen.RollingStyle = RollingFileAppender.RollingMode.Composite
rollAppen.File = "logs\\"
rollAppen.DatePattern = "'" + clsName.ToLower() + "'" + "yyyyMMdd'.log'"
rollAppen.LockingModel = New log4net.Appender.FileAppender.MinimalLock()
rollAppen.AppendToFile = True
rollAppen.StaticLogFileName = False
rollAppen.MaxSizeRollBackups = 3
rollAppen.MaximumFileSize = "100KB"
Dim layout As New log4net.Layout.PatternLayout("%d [%t] %-5p %c (line:%L) - %m%n")
rollAppen.Layout = layout
layout.ActivateOptions()
rollAppen.ActivateOptions()
Dim logg As ILog = LogManager.GetLogger(clsName)
Dim l As log4net.Repository.Hierarchy.Logger = DirectCast(logg.Logger, log4net.Repository.Hierarchy.Logger)
l.AddAppender(rollAppen)
l.Repository.Configured = True
Return logg
End Function
コードからローリングアペンダーを動的に生成したいが、同時に設定ファイルからロガーを設定したいので、次の設定ファイル呼び出し (Log4Net.config) があります。
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<appSettings>
<add key="log4net.Config" value="log4net.config"/>
<add key="log4net.Config.Watch" value="True"/>
</appSettings>
<log4net>
<logger name="ConsoleApplication1.LogTest2">
<level value="WARN" />
</logger>
<logger name="ConsoleApplication1.testCls">
<level value="INFO" />
</logger>
</log4net>
次に、次のコードで関数をテストします。
Dim cls As LogTest2 = New LogTest2()
Dim tCls As testCls = New testCls()
Dim l4n As log4net.ILog
Dim l4n2 As log4net.ILog
l4n = cls.genLogXMLCfg(tCls.GetType().ToString())
l4n2 = cls.genLogXMLCfg(cls.GetType().ToString())
l4n.Debug("... Here is a debug log -2.")
l4n.Info("... and an Info log.")
System.Threading.Thread.Sleep(3000)
l4n.Warn("... and a warning 1.")
l4n.Debug("... Here is a debug log -1.")
l4n.Warn("... and a warning 2.")
l4n.Warn("... and a warning 3.")
l4n2.Warn("l4n2 cls and a warning -1.")
l4n.Warn("... and a warning 4.")
l4n.Warn("... and a warning 5.")
Console.Write(" ... ... ... ")
System.Threading.Thread.Sleep(3000)
l4n.Warn("... and a warning 6.")
l4n.Debug("... Here is a debug log 1.")
l4n.Warn("... and a warning 7.")
l4n2.Debug("l4n2 cls Here is a debug log.")
l4n2.Info("l4n2 cls and an Info log.")
l4n.Fatal("... and a fatal .")
l4n2.Fatal("l4n2 and a fatal .")
l4n.Debug("... Here is a debug log 2.")
l4n.Warn("... and a warning 8.")
l4n.Error("... and an error.")
l4n.Debug("... Here is a debug log 3.")
l4n.Fatal("... and a fatal .")
l4n.Debug("... Here is a debug log 4.")
l4n2.Debug("l4n2 cls Here is a debug log.")
l4n2.Info("l4n2 cls and an Info log.")
l4n2.Warn("l4n2 cls and a warning.")
l4n2.Error("l4n2 cls and an error.")
l4n2.Fatal("l4n2 cls and a fatal .")
その後、logs フォルダー呼び出しで生成された 2 つのログ ファイル
**consoleapplication1.logtest220130610.log** and **consoleapplication1.testcls20130610.log**
The content are:

すべてOKです。しかし....プログラムの実行中に構成ファイルを変更すると、レベルをINFOからFATALに変更したとしましょう
<logger name="ConsoleApplication1.testCls">
<level value="FATAL" /> <!-- INFO to FATAL -->
</logger>
2 つのログ ファイルは次のとおりです。

ロガーデータを 1 つだけ変更しても、監視機能がログを正しく更新できず、他のログファイルに影響を与えるように見えるのはなぜでしょうか? 理由がわかりますか？私のコードの何が問題なのか
