????????????/*
????????????注：Test操作方法是異步執行的操作方法【前綴有?async????內容有await關鍵字】
????????????????該程序的執行順序是?主線程執行著Main函數中除Test之外的代碼；?與此同時?異步線程執行著相應方法；
????????????????但是一旦主線程執行完了，不管異步線程執沒執行完，都算是Main函數執行完畢，控制臺應用程序?窗口隨之自動關閉。



????????????注：如果運行程序后不去點任何鍵，則
??????????????????第一步、輸出“Main”
??????????????????第二步、執行到???第一個Console.ReadKey（）;?等待用戶在主線程中輸入文字
??????????????????第三步、輸出“1“????這一步是由?異步開啟的線程?做的；
??????????????????第四步、輸出“Main末尾??”
??????????????????第五步、執行到???第二個Console.Read
