如何知道 Windows 何时启动或关闭？

我需要用 C# 开发一个程序，找出 Windows 何时启动或关闭。

是否有一个日志文件可供我读取以了解 Windows 启动和关闭时间？或者您有什么想法如何做到这一点？

在 Reed Copsey 先生的帮助下，在下面找到了最佳答案question https://stackoverflow.com/questions/6185608/getting-server-restart-count-in-a-day-using-c.

根据本文 http://web.archive.org/web/20111104234407/http://www.c-sharpcorner.com/UploadFile/scottlysle/TimeSinceBootCS06052008055807AM/TimeSinceBootCS.aspx您可以使用 WMI 来获取上次启动日期/时间.

// define a select query
SelectQuery query =
    new SelectQuery(@"SELECT LastBootUpTime FROM Win32_OperatingSystem
       WHERE Primary='true'");

// create a new management object searcher and pass it
// the select query
ManagementObjectSearcher searcher =
    new ManagementObjectSearcher(query);

// get the datetime value and set the local boot
// time variable to contain that value
foreach(ManagementObject mo in searcher.Get())
{
    dtBootTime =
        ManagementDateTimeConverter.ToDateTime(
            mo.Properties["LastBootUpTime"].Value.ToString());

    // display the start time and date
    txtDate.Text = dtBootTime.ToLongDateString();
    txtTime.Text = dtBootTime.ToLongTimeString();
}
