新的延遲初始化

嘗試使用NLog創建日誌助手類。但是在創建屬性時出現以下錯誤。新的延遲初始化

錯誤BC30518重載決策失敗，因爲沒有可訪問的「新」可以用這些參數

Private Shared ReadOnly LoggingMap As New Lazy(Of Dictionary(Of TraceLevel, Action(Of String)))(Function() New Dictionary(Of TraceLevel, Action(Of String))() From { 
      {TraceLevel.Info, ClassLogger.Info}, 
      {TraceLevel.Debug, ClassLogger.Debug}, 
      {TraceLevel.[Error], ClassLogger.[Error]}, 
      {TraceLevel.Fatal, ClassLogger.Fatal}, 
      {TraceLevel.Warn, ClassLogger.Warn} 
})

我想爲它可用於如下調用。

''' <summary> 
''' Get property for Logger 
''' </summary> 
Private ReadOnly Property Logger() As Dictionary(Of TraceLevel, Action(Of String)) 
    Get 
     Return LoggingMap.Value 
    End Get 
End Property

找到答案感謝這樣的：nlog Logging Map using VB.Net

Private Shared ReadOnly LoggingMap As New Lazy(Of Dictionary(Of TraceLevel, Action(Of String))) _ 
(Function() New Dictionary(Of TraceLevel, Action(Of String)) From 
      {{TraceLevel.Info, AddressOf ClassLogger.Info}, 
      {TraceLevel.Debug, AddressOf ClassLogger.Debug}, 
      {TraceLevel.Error, AddressOf ClassLogger.Error}, 
      {TraceLevel.Fatal, AddressOf ClassLogger.Fatal}, 
      {TraceLevel.Warn, AddressOf ClassLogger.Warn} 
     })
