本文介绍了如何计算C＃中的系统正常运行时间和停机时间的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一些xml数据，他们正在传递last_time_down和last_time_up但是如何计算正常运行时间和停机时间百分比。
请查看我的xml数据。
我还需要计算。注意：我希望在今天或本月或昨天或过去24小时内获取数据过滤器。

我正在使用这种类型的计算，但我没有得到确切的数据。
var src = Convert.ToDateTime（result.GetString（result.GetOrdinal（ status_update_time）））;
var hm = new DateTime（src.Year，src.Month，src.Day， src.Hour，src.Minute， 0 ）;
var dow = Convert.ToDateTime（result.GetString（result.GetOrdinal（ last_time_down）））;
var dm = new DateTime（dow.Year，dow.Month，dow.Day， dow.Hour，dow.Minute， 0 ）;
var uptime = hm;
var 停机时间= hm - dm;
double up = uptime.Ticks / 6000 ;
double dt = downtime.Ticks / 6000 ;
double percentage =（ double ）（上/（上+ dt）* 100 ）;
string slastatus = percentage > Convert.ToDouble（_inputpercentage）？ PASSED： FAILED;
hostlist.Add（ new HostData
{
host_id = result.GetString（result.GetOrdinal（ host_id）），
status_update_time = result.GetString（result.GetOrdinal（ status_update_time）），
last_time_down = result.GetString（result.GetOrdinal（ last_time_down）），
alias = result.GetString（result.GetOrdinal （ 别名）），
display_name = result.GetString（result.GetOrdinal（< span class =code-string> display_name）） ，
uptime =（（ int ）Math.Ceiling（percentage））。ToString（ 0.00）+ ％，
status = slastatus，
totaluptime =（ float ）百分比
}）;
解决方案
不要使用刻度线。不要混淆时间（时间线上的一个点），持续时间（到时间点之间的时间跨度）。除了System.DateTime之外，还要使用System.TimeSpan类型：
System.DateTime first = // ...
System.DateTime second = System.DateTime.Now;
System.TimeSpan duration = second - first; // 运营商定义
var allYouWantedToKnowAboutDurationButWasAfraidToAsk = duration。 // ...任何内容，请参阅MSDN :: - ）

除了 Sergey Alexandrovich Kryukov [ ^ ]，我想提供样本（使用 LinqToXml [ ^ ]）：
var result = xdoc.Descendants（ hoststatus）
。选择（x = > new
{
hostid =（ int ）x.Element（ host_id），
statusUpdTime =（DateTime）x.Element（ status_update_time），
lastDownTime =（DateTime）x.Element（ last_time_down），
别名 =（ string ）x.Element （ a lias），
timeDiff =（TimeSpan）（（DateTime）x.Element（ status_update_time） - （DateTime）x.Element（ last_time_down））
}）;
结果：
hostid statusUpdTime lastDownTime alias timeDiff

I have some xml data they are passing last_time_down and last_time_up but how to calculate uptime and downtime with percentage.
Please see my xml data.
I need calculation also. Note : I want get data filter by today or this month or yesterday or last 24 hours.

I am using this type of calculation but am not getting exact data.
var src = Convert.ToDateTime(result.GetString(result.GetOrdinal("status_update_time")));
var hm = new DateTime(src.Year, src.Month, src.Day, src.Hour, src.Minute, 0);
var dow = Convert.ToDateTime(result.GetString(result.GetOrdinal("last_time_down")));
var dm = new DateTime(dow.Year, dow.Month, dow.Day, dow.Hour, dow.Minute, 0);
var uptime = hm;
var downtime = hm - dm;
double up = uptime.Ticks / 6000;
double dt = downtime.Ticks / 6000;
double percentage = (double)(up / (up + dt) * 100);
string slastatus = percentage > Convert.ToDouble(_inputpercentage) ? "PASSED" : "FAILED";
hostlist.Add(new HostData
{
host_id = result.GetString(result.GetOrdinal("host_id")),
status_update_time = result.GetString(result.GetOrdinal("status_update_time")),
last_time_down = result.GetString(result.GetOrdinal("last_time_down")),
alias = result.GetString(result.GetOrdinal("alias")),
display_name = result.GetString(result.GetOrdinal("display_name")),
uptime = ((int)Math.Ceiling(percentage)).ToString("0.00") + "%",
status = slastatus,
totaluptime = (float)percentage
});
解决方案
Don't use ticks. Don't mix up time (a point on the time line), with duration (time span between to points in time). Use the typeSystem.TimeSpanin addition toSystem.DateTime:
System.DateTime first = //... System.DateTime second = System.DateTime.Now; System.TimeSpan duration = second - first; // operator defined var allYouWantedToKnowAboutDurationButWasAfraidToAsk = duration.// ...anything, see MSDN: :-)

In addition to solution 1 by Sergey Alexandrovich Kryukov[^], i would like to provide sample (using LinqToXml[^]):
var result = xdoc.Descendants("hoststatus") .Select(x=>new { hostid = (int)x.Element("host_id"), statusUpdTime = (DateTime)x.Element("status_update_time"), lastDownTime = (DateTime)x.Element("last_time_down"), alias = (string)x.Element("alias"), timeDiff = (TimeSpan)((DateTime)x.Element("status_update_time") - (DateTime)x.Element("last_time_down")) });
result:
hostid statusUpdTime lastDownTime alias timeDiff 3132 2015-09-19 07:58:26 1970-01-01 02:00:00 ex Test Server 16697.05:58:26
