如何抓取從電腦從 Sleep 狀態回復或進入 Sleep 狀態，僅需要抓取以下的事件，即可完成。

1. Windows 內建了 power 狀態改變的事件，只需增加以下的程式碼

2. 程式執行了睡眠與從睡眠中喚醒，範例的執行結果如下：

C# Sleep, Hibernate 喚醒

English
========================================================================
Add below code in your project.

using Microsoft.Win32;


private void Form1_Load(object sender, EventArgs e)
{
        SystemEvents.PowerModeChanged += new PowerModeChangedEventHandler(SystemEvents_PowerModeChanged);
}


void SystemEvents_PowerModeChanged(object sender, PowerModeChangedEventArgs e)
{
        if (e.Mode.Equals(PowerModes.Resume))
        {
                //Do  what you want when system back.
        }
}

System will occur the PowerModeChanged event when system back from Sleep or Hibernate. We can use this event to do what we want.

在程式中增加以下程式碼：

using Microsoft.Win32;


private void Form1_Load(object sender, EventArgs e)
{
        SystemEvents.PowerModeChanged += new PowerModeChangedEventHandler(SystemEvents_PowerModeChanged);
}


void SystemEvents_PowerModeChanged(object sender, PowerModeChangedEventArgs e)
{
        if (e.Mode.Equals(PowerModes.Resume))
        {
                //Do  what you want when system back.
        }
}

當系統從 S3 或 S4 恢復時，會觸發 PowerModeChange event，因此就能完成所想對應的事情。
