此IDisposable代码是否需要Class Object的手册.Dipose？

如何解决此IDisposable代码是否需要Class Object的手册.Dipose？

我在Class对象内使用Implements Idisposable，因为在对Class方法中的DLL进行调用期间抛出了回调异常。这种想法是，当DLL仍在处理时，Class进行垃圾回收的时间过早。

但是，我发现并使用了MSDN（如下）中的一些代码，并在该类末尾用该代码替换了自动创建的代码，它似乎可以工作：

#Region "Idisposable"
    '---Code entirely copied from MSDN

    Private managedResource As System.ComponentModel.Component
    Private unmanagedResource As IntPtr
    Protected disposed As Boolean = False

    Protected Overridable Overloads Sub dispose(
        ByVal disposing As Boolean)
        If Not Me.disposed Then
            If disposing Then
                Try
                    managedResource.dispose()
                Catch
                End Try
            End If
            ' Add code here to release the unmanaged resource.
            unmanagedResource = IntPtr.Zero
            ' Note that this is not thread safe. 
        End If
        Me.disposed = True
    End Sub

    'Private Sub AnyOtherMethods()
    'If Me.disposed Then
    'Throw New ObjectdisposedException(Me.GetType().ToString,"This object has been disposed.")
    'End If
    'End Sub

    'Do not change or add Overridable to these methods. 
    'Put cleanup code in dispose(ByVal disposing As Boolean). 
    Public Overloads Sub dispose() Implements Idisposable.dispose
        '  dispose(True)
        GC.SuppressFinalize(Me)
    End Sub

    Protected Overrides Sub Finalize()
        '  dispose(False)
        MyBase.Finalize()
    End Sub
#End Region

有一个警告：如果在实例化该类之后，我循环并等待在该类内部方法的最后（调用DLL）将全局布尔参数设置为true，然后处置该对象，回调错误将会出现。

Public ProcFinished As Boolean

Public Class Procclass 
  Sub New(param1,param2,param3)
     MyMethodThatCallsDLL(param1,param3)
  End Sub

  Sub MyMethodThatCallsDLL(param1,param3)
    
    'Call DLL
    ReferenceName.DLLName(param1,param3) 

    '...do some math...

    ProcFinished = True
  End Sub

End Class   


'...somewhere else in Project
ProcFinished = False

Dim myproc As New Procclass(param1,param3)

Do Until ProcFinished = True 'waits till Public ProcFinished is True
Loop

myproc.dispose()  '(don't kNow if this is needed?)

问题是，给定IDiposable代码，是否需要上述myproc.dispose（）代码？我不能很好地理解Idisposable代码，但看起来确实有些技巧，可以将类分配为托管代码，因此它不会被GC（？）杀死。
