我在线程中运行以下代码来枚举活动目录中的本地机器。这需要一些时间才能完成(大约 5-10 秒),因此如果用户在枚举完成之前退出应用程序,则应用程序需要 5-10 秒才能退出。我尝试了 thread.abort 但因为它正在等待For Each SubChildEntry In SubParentEntry.Children
完成它在返回之前不会中止。
Dim childEntry As DirectoryEntry = Nothing
Dim ParentEntry As New DirectoryEntry
ParentEntry.Path = "WinNT:"
For Each childEntry In ParentEntry.Children
Windows.Forms.Application.DoEvents()
Select Case childEntry.SchemaClassName
Case "Domain"
Dim SubChildEntry As DirectoryEntry
Dim SubParentEntry As New DirectoryEntry
SubParentEntry.Path = "WinNT://" & childEntry.Name
'The following line takes a long time to complete
'the thread will not abort until this returns
For Each SubChildEntry In SubParentEntry.Children
Select Case SubChildEntry.SchemaClassName
Case "Computer"
_collServers.Add(SubChildEntry.Name.ToUpper)
End Select
Next
End Select
Next
RaiseEvent EnumComplete()
