事件调用的方法不在范围

我正在建立一个通过呼叫服务器(星号)接受呼叫并触发事件的系统

_manager.NewState += new NewStateEventHandler(manager_NewStateEvent);

AsteriskManager.cs

以下是manager_NewStateEvent

private void manager_NewStateEvent(object sender, NewStateEvent e)
{
    managerState = e.ChannelStateDesc;
    if (OnPhoneStateChange != null)
        OnPhoneStateChange(e);
    Console.WriteLine("New State : " + e.ChannelStateDesc);

     switch (e.ChannelStateDesc)
     {
         case "Down":
         case "OffHook":
         case "Dialing":
         case "Ring":
         case "Ringing":
         case "Up":
         case "Busy":
                break;
     }
 }

Form1.cs的

void _manager_OnPhoneStateChange(Asterisk.NET.Manager.Event.NewStateEvent e)
{
    StateLabel.Text = e.ChannelStateDesc;
    this.Refresh();
}

_manager.NewState是呼叫进入时被调用的事件。然后在我的C#表单中,我试图根据我得到的响应更改标签,但标签没有更新。

(我试图通过点击按钮强制方法_manager_OnPhoneStateChange,它工作正常)
