How would you simplify Entering and Exiting a ReaderWriterLock?

Question

This seems very noisy to me. Five lines of overhead is just too much.

m_Lock.EnterReadLock()
Try
    Return m_List.Count
Finally
    m_Lock.ExitReadLock()
En         


        

Answer 1

I ended up doing this, but I'm still open to better ways or flaws in my design.

Using m_Lock.ReadSection
    Return m_List.Count
End Using

This uses this extension method/class:

 Public Function ReadSection(ByVal lock As ReaderWriterLockSlim) As ReadWrapper
    Return New ReadWrapper(lock)
End Function


Public NotInheritable Class ReadWrapper
    Implements IDisposable

    Private m_Lock As ReaderWriterLockSlim
    Public Sub New(ByVal lock As ReaderWriterLockSlim)
        m_Lock = lock
        m_Lock.EnterReadLock()
    End Sub
    Public Sub Dispose() Implements IDisposable.Dispose
        m_Lock.ExitReadLock()
    End Sub

End Class
