从C#与Lotus Notes交互的最佳方法和推荐做法是什么？

Question

特别是,我必须以最快和最可靠的方式从Lotus Notes文件中提取所有消息和附件.可能相关的另一点是我需要从辅助线程执行此操作.

编辑

谢谢你的答案 - 两者都很好.我应该提供更多背景资料.

我们目前有一个使用Notes COM API的后台线程的WinForms应用程序.

然而它似乎不稳定.(当然可能是我们做错了.)例如,我们发现我们必须在主线程上预先初始化Notes会话,否则对后台线程上的session.CreateDXLExporter()的调用会引发异常.

我真的很讨厌那个NotesSession COM对象.

您不能在其初始化的线程之外的其他线程中使用它..NET中的线程是光纤,真正的底层线程可能随时发生变化.

所以我建议在使用块中以这种方式使用它:

Imports Domino
Imports System.Threading

Public Class AffinitedSession
    Implements IDisposable

    Private _session As NotesSession
    Public Sub New(ByVal pass As String)
        Thread.BeginThreadAffinity()
        _session = New NotesSession()
        _session.Initialize(pass)
    End Sub

    Public ReadOnly Property NotesSession() As NotesSession
        Get
            Return _session
        End Get
    End Property

    Private disposedValue As Boolean = False        ' To detect redundant calls

    ' IDisposable
    Protected Overridable Sub Dispose(ByVal disposing As Boolean)
        If Not Me.disposedValue Then
            If disposing Then
                ' TODO: free other state (managed objects).
            End If

            ' TODO: free your own state (unmanaged objects).
            ' TODO: set large fields to null.
            _session = Nothing
            Thread.EndThreadAffinity()
        End If
        Me.disposedValue = True
    End Sub

#Region " IDisposable Support "
    ' This code added by Visual Basic to correctly implement the disposable pattern.
    Public Sub Dispose() Implements IDisposable.Dispose
        ' Do not change this code.  Put cleanup code in Dispose(ByVal disposing As Boolean) above.
        Dispose(True)
        GC.SuppressFinalize(Me)
    End Sub
#End Region

End Class

注意Thread.BeginThreadAffinity()和Thread.EndThreadAffinity()

那些是你的朋友.

干杯!
