C# 转为 VB.net

小弟在将C#转为VB时，遇见如下问题，请各位路过时，指教一二，谢谢！

将C#转为VB时，这段代码总是编译不成功
Public Custom Event SolicitationEvent As EventHandler
        AddHandler(ByVal value As EventHandler)
            _solicitationEvent += value
        End AddHandler

        RemoveHandler(ByVal value As EventHandler)
            _solicitationEvent -= value
        End RemoveHandler
    End Event
错误信息：
缺少事件“SolicitationEvent”的“RaiseEvent”定义。
“Private Event _solicitationEvent(sender As Object, e As System.EventArgs)”是事件，不能直接调用。请使用“RaiseEvent”语句引发事件。
“Private Event _solicitationEvent(sender As Object, e As System.EventArgs)”是事件，不能直接调用。请使用“RaiseEvent”语句引发事件。

下面是源码
