本文實例講述了WinForm實現最小化到系統托盤方法。分享給大家供大家參考。具體分析如下：
有個叫NotifyIcon的控件
1、建個WinForm項目，其它操作略過。
2、拉個NotifyIcon控件，將屬性Visable設置成False，在Text屬性上隨便填些文件。
3、實現Form的SizeChanged事件，代碼如下：
?
1 2 3 4 5 if(this.WindowState == FormWindowState.Minimized) //判斷是否最小化 { this.ShowInTaskbar = false; //不顯示在系統任務欄 notifyIcon.Visible = true; //托盤圖標可見 }4、實現NotifyIcon控件的DoubleClick事件，代碼如下：
?
1 2 3 4 5 6 if(this.WindowState == FormWindowState.Minimized) { this.ShowInTaskbar = true; //顯示在系統任務欄 this.WindowState = FormWindowState.Normal; //還原窗體 notifyIcon.Visible = false; //托盤圖標隱藏 }例題：
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 private ContextMenu notifyiconMnu; #region 最小化到任務欄 /// <summary> /// 最小化到任務欄 /// </summary> private void Initializenotifyicon() { //定義一個MenuItem數組，並把此數組同時賦值給ContextMenu對象 MenuItem[] mnuItms = new MenuItem[3]; mnuItms[0] = new MenuItem(); mnuItms[0].Text = "顯示窗口"; mnuItms[0].Click += new System.EventHandler(this.notifyIcon1_showfrom); mnuItms[1] = new MenuItem("-"); mnuItms[2] = new MenuItem(); mnuItms[2].Text = "退出系統"; mnuItms[2].Click += new System.EventHandler(this.ExitSelect); mnuItms[2].DefaultItem = true; notifyiconMnu = new ContextMenu(mnuItms); notifyIcon1.ContextMenu = notifyiconMnu; //為托盤程序加入設定好的ContextMenu對象 } private void notifyIcon1_DoubleClick(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Minimized) { this.Show(); this.ShowInTaskbar = true; this.WindowState = FormWindowState.Normal; notifyIcon1.Visible = false; } } public void notifyIcon1_showfrom(object sender, System.EventArgs e) { if (this.WindowState == FormWindowState.Minimized) { this.Show(); this.ShowInTaskbar = true; this.WindowState = FormWindowState.Normal; notifyIcon1.Visible = false; } } public void ExitSelect(object sender, System.EventArgs e) { //隱藏托盤程序中的圖標 notifyIcon1.Visible = false; //關閉系統 this.Close(); this.Dispose(true); } #endregion private void Form_main_SizeChanged(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Minimized) //判斷是否最小化 { notifyIcon1.Visible = true; this.Hide(); this.ShowInTaskbar = false; Initializenotifyicon(); } }希望本文所述對大家的C#程序設計有所幫助。
