vb是否支持虚拟事件的clr概念?

不,这是我们已经研究过的支持方法,但在给定的语言周期中没有达到当前的标准。

VB是否支持自定义事件的层次结构思想?

对。您可以使用自定义事件语法来允许层次结构控制的事件。

MustInherit Class Base
    Public Custom Event Event1 As EventHandler
        AddHandler(ByVal value As EventHandler)
            AddEvent1(value)
        End AddHandler

        RemoveHandler(ByVal value As EventHandler)
            RemoveEvent1(value)
        End RemoveHandler

        RaiseEvent(ByVal sender As Object, ByVal e As System.EventArgs)
            RaiseEvent1(sender, e)
        End RaiseEvent

    End Event

    Protected MustOverride Sub AddEvent1(ByVal value As EventHandler)
    Protected MustOverride Sub RemoveEvent1(ByVal value As EventHandler)
    Protected MustOverride Sub RaiseEvent1(ByVal sender As Object, ByVal e As EventArgs)

End Class
