vb.net - 多个背景工作人员vb.net

Question

我需要使用backgroundwoker在后台运行多个任务

例如dim mybacgroundwokers(10) as backgroundwoker
在backgroundworker事件过程中，我可以做这样的事情吗，因为我不知道

mybackgroundwoker_dowork(,,index)

select case index
case 1
'dowork for backgroundworker1
case 2
'dowork for backgroundworker2
end select

或我如何处理多个背景工作人员

如果backgroundworker不可能做到这一点，那么我该如何使用线程多线程处理呢？

谢谢

您应该使用多个具有适当名称的Backgroundworkers，例如:

Dim CountSheepBackgroundWorker As BackgroundWorker WithEvents
Dim CountStarsBackgroundWorker As BackgroundWorker WithEvents
Dim StackEggsBackgroundWorker As BackgroundWorker WithEvents

如果您绝对要使用数组，Visual Studio将无法帮助您使用DoWork Subs:

Dim MyBackgroundWorkers(9) As BackgroundWorker
' Add first
MyBackgroundWorkers(0) = new BackgroundWorker
AddHandler MyBackgroundWorkers(0), AddressOf FirstBackgroundWorker_DoWork
MyBackgroundWorkers(0).RunWorkerAsync()
' Add second etc
