C#编写自动关机程序复习的知识
首先一个程序第一要素是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。
namespace 关机任务管理V1._0
{
public partial class Form1 : Form
{
int shi, fen, miao;
Int32 time_set;
int Flag_True = 0;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void numericUpDown1_ValueChanged(object sender, EventArgs e)
{
if (numericUpDown1.Value == -1)
numericUpDown1.Value = 60;
else if (numericUpDown1.Value == 61)
numericUpDown1.Value = 0;
}
private void numericUpDown2_ValueChanged(object sender, EventArgs e)
{
if (numericUpDown2.Value == -1)
numericUpDown2.Value = 60;
else if (numericUpDown2.Value == 61)
numericUpDown2.Value = 0;
}
private void numericUpDown3_ValueChanged(object sender, EventArgs e)
{
if (numericUpDown3.Value == 25)
numericUpDown3.Value = 0;
else if (numericUpDown3.Value == -1)
numericUpDown3.Value = 24;
}
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;
}
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;
}
}
}
}
private void label5_Click(object sender, EventArgs e)
{
}
private void label4_Click(object sender, EventArgs e)
{
}
private void label3_Click(object sender, EventArgs e)
{
}
private void label6_Click(object sender, EventArgs e)
{
}
private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
{
this.Visible = true;
this.WindowState = FormWindowState.Normal;
this.notifyIcon1.Visible = false;
}
//最小化代码
private void Form1_SizeChanged(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Hide();
this.notifyIcon1.Visible = true;
}
}
}
}
界面如下：
