Log4net-如何记录WCF中的调用方法名称

Question

我已经为log4net编写了一个Singleton包装器，它将在我的WCF服务的所有层中调用。我无法记录调用方法名称。请建议，如果有任何输入从我的下面的代码。谢谢

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Imports log4net
Imports System.Reflection

Public Class Logger
Implements ILog
Private Shared m_instance As Logger
Private Shared log As log4net.ILog = Nothing
Public Sub New()
    If log Is Nothing Then
        'log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType) ' -> This always logs 'Logger'
        log = log4net.LogManager.GetLogger(Assembly.GetCallingAssembly(), "MyLogger")  ' -> This always logs 'MyLogger'
    End If
End Sub
Public Shared ReadOnly Property Write() As Logger
    Get
        m_instance = New Logger()
        Return m_instance
    End Get
End Property
Public Sub Debug(msg As String) Implements ILog.Debug
    log.Debug(msg)
End Sub
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''  
Public Interface ILog
     Sub Debug(msg As String)
End Interface
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

我已经使记录方法名称变得更加简单，如下所示。但我必须将类名作为参数传递。请建议这个设计可以接受吗？

''''' Calling code ''''''''''''''''''''
Logger(of MyClassName).Debug("message")

''''''Log4net wrapper'''''''''''''''''''''
Imports log4net
Imports System.Reflection

Public NotInheritable Class Logger(Of T)
Private Shared log As log4net.ILog = Nothing
Private Shared ReadOnly Property LogProvider() As log4net.ILog
    Get
        If (log Is Nothing) Then
            Dim CallingMethod As String = GetType(T).ToString() & "." & (New StackTrace()).GetFrame(2).GetMethod().Name
            log = log4net.LogManager.GetLogger(CallingMethod)
        End If
        Return log
    End Get
End Property
Public Shared Sub Debug(msg As String)
    LogProvider.Debug(msg)
End Sub

一个日志实例只能有一个名称，您不能更改它。如果您想在每个方法中使用不同的名称，您需要为ech方法制作一个记录器。

    log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType) ' -> This always logs 'Logger'
    log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().Name) ' -> This gives you the name of the current method
    log = log4net.LogManager.GetLogger(Assembly.GetCallingAssembly(), "MyLogger")  ' -> This always logs 'MyLogger'

在您的方法中创建记录器，如：

    ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().Name) ' -> This gives you the name of the current method

你会有一个带有方法名称的记录器，我会添加类的名称：

    ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType + "." + MethodBase.GetCurrentMethod().Name) ' -> This gives you the name of the current method
