VB.NET中事件的GetInvocationList

现在我想将以下函数转换为VB.NET

private void BroadcastMessage(ChatEventArgs e)
{

    ChatEventHandler temp = ChatEvent;

    if (temp != null)
    {
        foreach (ChatEventHandler handler in temp.GetInvocationList())
        {
            handler.BeginInvoke(this,e,new AsyncCallback(EndAsync),null);
        }
    }
}

但是我遇到了一些问题,因为编译器不接受以下代码

Private Sub BroadcastMessage(ByVal e As ChatEventArgs)

    Dim handlers As EventHandler(Of ChatEventArgs) = ChatEvent

    If handlers IsNot Nothing Then

        For Each handler As EventHandler(Of ChatEventArgs) In handlers.GetInvocationList()

            handler.BeginInvoke(Me,New AsyncCallback(AddressOf EndAsync),Nothing)

        Next

    End If

End Sub

它说

Public Shared Event ChatEvent(sender
As Object,e As ChatEventArgs)’ is an
event,and cannot be called directly

接下来,是否有可能在VB.NET中获得以某种其他方式链接到某个事件的处理程序？
