無法找到類型或命名空間名稱'Button'（您是否缺少using指令或程序集引用？）

我在想什麼我不能通過這種簡單的tic tac腳趾遊戲來弄清楚它。無法找到類型或命名空間名稱'Button'（您是否缺少using指令或程序集引用？）

另外我怎樣才能合併一個水平滾動條列表框來選擇播放器？玩家1 =（x）或玩家2 =（O）

在此先感謝！

主要形式 - xGameForm

      for (int i = 0; i < 9; i++) 

      this._buttonArray[i].Click += new System.EventHandler(this.ClickHandler);

Button處於System.Windows.Forms命名空間的類。
除非您導入命名空間，編譯器將不知道您想要哪個類。

您需要通過添加using System.Windows.Forms;到類的頂部導入命名空間..

謝謝，工作！還有一個問題，我怎樣才能添加一個水平滾動條「xGameScrollBar」的列表框「xGameListBox」來選擇播放器？ Player1 =（x）或Player2 =（O） – 2010-05-21 15:55:01

我不確定你的意思。 – SLaks 2010-05-21 15:58:32

您需要添加一個using指令使用System.Windows.Forms的與您的文件RESULT1類，或明確引用System.Windows.Forms.Button。否則complire不知道按鈕是什麼。
