如何获取带有日期和时间的上次系统关闭状态 [英] How To get Last System Shut Down Status With Date and Time

问题描述

我需要c#中的以下内容:-

1.上次系统关闭来自事件查看器的日期和时间.事件ID = 1078
2.上次系统关闭模式，即正确关闭/意外关闭(错误关闭)事件ID = 6006
3.总系统运行时间.总正常运行时间.
以上所有内容在事件查看器中都可用，但是如何使用WMI C#获得唯一的最后一条记录.


问候

I need the Following things in c#:-

1. Last system OFF Date and Time From event Viewer. Event ID = 1078
2. Last System OFF mode i.e Proper shut down / un expected (improper Shut Down) Event ID = 6006
3. Total System Running duration. Total Up Time.
All the above things are available in Event Viewer, but how can I get the only last record using WMI C#.

推荐答案

试试这个代码:

Hi,
try this code:

private void button1_Click(object sender, EventArgs e)
{
   MessageBox.Show(GetLastSystemShutdown().ToString());
}

public static DateTime GetLastSystemShutdown()
{
   string sKey = @"System\CurrentControlSet\Control\Windows";
   Microsoft.Win32.RegistryKey key = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(sKey);

   string sValueName = "ShutdownTime";
   byte[] val = (byte[])key.GetValue(sValueName);
   long valueAsLong = BitConverter.ToInt64(val, 0);
   return DateTime.FromFileTime(valueAsLong);
}
