This article mainly shows you "how to write an automatic shutdown program in C#", which is easy to understand and well-organized. I hope it can help you solve your doubts. Let the editor lead you to study and learn the article "how to write an automatic shutdown program in C#".

First of all, the element of a program is logo.

You can set the program icon in the settings and set it in ICON.

The ICON icon can be downloaded online.

These are all superficial skills.

Buton, Label, Timer and Notiflcon controls are involved in the program.

Button button control, you can design click events

As follows:

one

seven

eight

nine

ten

eleven

twelve

thirteen

fourteen

fifteen

sixteen

seventeen

eighteen

nineteen

twenty

Private void button1_Click (object sender, EventArgs e)

{

/ / int shi, fen, miao

If (Flag_True = = 0)

{

Flag_True = 1

}

Else

{

Button1.Text = "OK"

Label6.Text = ""

Label7.Text = ""

Label5.Text = ""

/ / label1.Text = "timing shutdown setting"

Flag_True = 0

}

Shi = (int) numericUpDown3.Value

Fen = (int) numericUpDown2.Value

Miao = (int) numericUpDown1.Value

Time_set = shi * 3600 + fen * 60 + miao

}

Label control is easy to operate.

Can display characters, and its members have text, you can change the text at any time

The timer control is equivalent to an embedded timer, setting ENABLE in the row column of the property and setting the interval interval of 500is half a second.

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 = "cancel"

Label6.Text = "remaining shutdown time"

Label7.Text = "seconds"

Label5.Text = "0"

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

} / / 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 = "cancel"

Label6.Text = "remaining shutdown time"

Label7.Text = "seconds"

/ / extra/3600

Label5.Text = extra.ToString ()

}

Else

{

Flag_True = 0

}

}

}

}

Above, I enter the interrupt every half a second to judge whether the shutdown time has been reached if the scheduled shutdown has been set, and show how many seconds of shutdown are left. If the timing shutdown is not set, it will not be displayed.

The text of both button1 and Label can be changed at any time.

Basic function setup completed

Then there is a setting that is minimized to the tray.

Use the Notiflcon control

This control sets the minimization icon, where you can set the icon icon.

He comes with events such as mouse clicks, double clicks, clicks, double clicks.

one

two

three

four

five

six

Private void notifyIcon1_MouseClick (object sender, MouseEventArgs e)

{

This.Visible = true

This.WindowState = FormWindowState.Normal

This.notifyIcon1.Visible = false

}

Above I set up the mouse click, the code is to restore visualization, the normal window.

Then, when the program is minimized, it can be hidden below.

eight

Private void Form1_SizeChanged (object sender, EventArgs e)

{

If (this.WindowState = = FormWindowState.Minimized)

{

This.Hide ()

This.notifyIcon1.Visible = true

}

}

The above is a shutdown program, do their own fun.
