C#編寫自動關機程序復習的知識

開發后端

上面我每隔半秒進入中斷一次，判斷，如果已經設置過定時關機，就判斷是否到達關機時間，并顯示還剩多少秒關機。如果沒有設置定時關機，就不顯示。

[[148264]]

首先一個程序***要素是logo

在設置里面可以設置程序圖標，在ICON里設置。

ICON圖標可以在網上下載。

這些都是表面功夫

程序中涉及到Buton、Label、Timer、Notiflcon控件

Button按鈕控件，可以設計點擊事件

如下所示：

private void button1_Click(object sender, EventArgs e)

{

// int shi, fen, miao;

if (Flag_True == 0)

{

Flag_True = 1;

}

else

{

button1.Text = "確定";

label6.Text = " ";

label7.Text = " ";

label5.Text = " ";

//label1.Text = "定時關機設置";

Flag_True = 0;

}

shi = (int)numericUpDown3.Value;

fen = (int)numericUpDown2.Value;

miao = (int)numericUpDown1.Value;

time_set = shi * 3600 + fen * 60 + miao;

}

label控件操作簡單

能夠顯示字符，并且其成員有text，可以隨時更改文本

timer控件相當于嵌入式中的定時器，在屬性中行為一欄中設置ENABLE 并且設置interval時間間隔500就是半秒。

private void timer1_Tick(object sender, EventArgs e)

{

Int32 time_now;

Int32 extra;

if (Flag_True == 1)

{

if (DateTime.Now.Minute == fen && DateTime.Now.Hour == shi && DateTime.Now.Second == miao)

{

button1.Text = "取消";

label6.Text = "剩余關機時間";

label7.Text = "秒";

label5.Text = "0";

System.Diagnostics.Process.Start("shutdown","-s -t 0");//關機程序

}//shutdown

else

{

time_now = DateTime.Now.Second + DateTime.Now.Minute * 60 + DateTime.Now.Hour * 3600;

extra = time_set - time_now;

if (extra > 0)

{

button1.Text = "取消";

label6.Text = "剩余關機時間";

label7.Text = "秒";

//extra/3600

label5.Text = extra.ToString();

}

else

{

Flag_True = 0;

}

其中button1和Label的text都可以隨時更改。

基本功能設置完成

接下來還有一個最小化到托盤的設置

用到Notiflcon控件

此控件設置最小化圖標，在設置里可以設置icon圖標。

他帶有的事件有鼠標單擊，鼠標雙擊，單擊，雙擊。

private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)

{

this.Visible = true;

this.WindowState = FormWindowState.Normal;

this.notifyIcon1.Visible = false;

}

上述我設置了鼠標單擊，代碼里是恢復可視化，正常窗口。

再之得設置程序最小化時隱藏在下邊

private void Form1_SizeChanged(object sender, EventArgs e)

{

if (this.WindowState == FormWindowState.Minimized)

{

this.Hide();

this.notifyIcon1.Visible = true;

}

上述就是一個關機程序，自己做著玩的。。
