With the newer versions of VB.NET you can use a lambda expression inline instead of an entire method (if you want)
使用较新版本的 VB.NET，您可以使用内联 lambda 表达式而不是整个方法（如果需要）
Dim MyButton as New Button()
MyButton.Name = "MyButton"
AddHandler MyButton.Click, Sub(sender2, eventargs2)
'code to do stuff
'more code to do stuff
End Sub
