我有一些问题要将我的VB6项目转换为VB.NET

我不明白这个"AddressOf"函数应该如何在VB.NET中使用

我的VB6代码:

Declare Function MP4_ClientStart Lib "hikclient.dll" _
  (pClientinfo As CLIENT_VIDEOINFO, ByVal abab As Long) As Long

Public Sub ReadDataCallBack(ByVal nPort As Long, pPacketBuffer As Byte, _
  ByVal nPacketSize As Long)

  If Not bSaved_DVS Then
    bSaved_DVS = True
    HW_OpenStream hChannelHandle, pPacketBuffer, nPacketSize
  End If
    HW_InputData hChannelHandle, pPacketBuffer, nPacketSize

End Sub

nn1 = MP4_ClientStart(clientinfo, AddressOf ReadDataCallBack)
