推荐答案

简单-使用AddHandler. MSDN [

Simple - use AddHandler. MSDN[^] shows you how.

' First define the Event, then the delegate Method.
AddHandler backgroundWorker1.DoWork, AddressOf work

与C#相比，它有点肿，但这是VB中的唯一方法:)
对于您的其他代码此转换器 [

It''s a bit bloated compared to C#, but it''s the only way in VB :)
For your other code this convertor[^] will probably do fine.
Good luck!

AddHandler BackgroundWorker1.DoWork, AddressOf work.Invoke
