我試圖發送自定義命令的Windows服務。我的應用程序有一個窗口服務和一個窗體。當服務運行時，我想使用按鈕單擊事件在獨立存儲中創建一個文件。我正在使用本教程http://arcanecode.com/2007/05/30/windows-services-in-c-sending-commands-to-your-windows-service-part-7/。當我運行該程序並單擊該按鈕時似乎沒有任何事情發生，並且該文件未放置到獨立存儲中。我已經在這些方法上設置了斷點，以查看它們是否執行並且它們似乎有效。我不確定按鈕點擊方法是否可以從表單中的服務中獲得隔離存儲代碼，但根據本教程我看不出問題會是什麼。下面的源代碼。發送命令到Windows服務
