.net - 在锁内返回有什么区别吗？

Question

样本一

Public _objLock As Object = New Object
Public ReadOnly Property MyObjects() As IEnumerable(Of Object)
    Get
        SyncLock _objLock
            If _myObjects Is Nothing Then
                _myObject = LoadMyObjects()
            End If
            Return _myObjects
        End SyncLock
    End Get
End Property

样本二

Public _objLock As Object = New Object
Public ReadOnly Property MyObjects() As IEnumerable(Of Object)
    Get
        SyncLock _objLock
            If _myObjects Is Nothing Then
                _myObject = LoadMyObjects()
            End If              
        End SyncLock
        Return _myObjects
    End Get
End Property

这些实现之间会有什么区别吗？

Answer 1

不，在锁内返回没有区别。一旦你离开锁，它就会不复存在。
