C#编写自动关机程序复习的知识-c语言自动关机代码

[[148264]]

首先一个程序***要素是logo

在设置里面可以设置程序图标，在ICON里设置。

ICON图标可以在网上下载。

这些都是表面功夫

程序中涉及到Buton、Label、Timer、Notiflcon控件

Button按钮控件，可以设计点击事件

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 = "确定";

label6.Text = " ";

label7.Text = " ";

label5.Text = " ";

//label1.Text = "定时关机设置";

Flag_True = 0;

}

shi = (int)numericUpDown3.Value;

fen = (int)numericUpDown2.Value;

miao = (int)numericUpDown1.Value;

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

}

label控件操作简单

能够显示字符，并且其成员有text，可以随时更改文本

timer控件相当于嵌入式中的定时器，在属性中行为一栏中设置ENABLE 并且设置interval时间间隔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 = "剩余关机时间";

label7.Text = "秒";

label5.Text = "0";

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

}//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 = "剩余关机时间";

label7.Text = "秒";

//extra/3600

label5.Text = extra.ToString();

}

else

{

Flag_True = 0;

}

上面我每隔半秒进入中断一次，判断，如果已经设置过定时关机，就判断是否到达关机时间，并显示还剩多少秒关机。如果没有设置定时关机，就不显示。

其中button1和Label的text都可以随时更改。

基本功能设置完成

接下来还有一个最小化到托盘的设置

用到Notiflcon控件

此控件设置最小化图标，在设置里可以设置icon图标。

他带有的事件有鼠标单击，鼠标双击，单击，双击。

private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)

{

this.Visible = true;

this.WindowState = FormWindowState.Normal;

this.notifyIcon1.Visible = false;

}

上述我设置了鼠标单击，代码里是恢复可视化，正常窗口。

再之得设置程序最小化时隐藏在下边

private void Form1_SizeChanged(object sender, EventArgs e)

{

if (this.WindowState == FormWindowState.Minimized)

{

this.Hide();

this.notifyIcon1.Visible = true;

}

上述就是一个关机程序，自己做着玩的。。

整体构架如下图所示。
