Disposing of Objects from a Generic.List(Of ...)

[woogoo]

Hi,

I have an Generic.List(Of MyObjects) these Objects implement IDisposable and as a result I want to clean up on exit.

Regardless of how I attack this I get an error when trying this (or similar):

Protected Overrides Sub OnStop()
        ' Service is stopping so clean up.
        Dim m_Object As MyObject = Nothing
        For Each m_Object In m_Objects
            m_Objects.Remove(m_Object)
            m_Object.Dispose()
        Next
    End Sub

The error I get is

Collection was modified; enumeration operation may not execute.

I can only assume that m_Object is only a reference to the actual Instance in the List(Of...). Does anyone know how I can clean up properly?

Use the for loop to just call the Dispose method. Afterwards, delete or replace the whole list.

That's what I love about this site. I'd worked that out, and was about to update the post only to have a reply; brilliant.

Thanks for your time anyway.
