Get elapsed time since application start
提问by Michael IV
I am porting an app from ActionScript3.0 (Flex) to C# (WPF).AS3.0 has got a handy utility called getTimer()which returns time since Flash Virtual machine start in milliseconds.I was searching in C# through classes as
我正在将应用程序从 ActionScript3.0 (Flex) 移植到 C# (WPF)。AS3.0 有一个名为getTimer()的方便实用程序，它以毫秒为单位返回自 Flash 虚拟机启动以来的时间。我通过类在 C# 中搜索
DateTime
DispatcherTimer
System.Diagnostics.Process
System.Diagnostics.Stopwatch
but found nothing like this.It seems a very basic feature to me.For example Unity3D which runs on Mono has something familiar. Do I miss some utility here?
但没有发现这样的东西。对我来说，这似乎是一个非常基本的功能。例如，在 Mono 上运行的 Unity3D 有一些熟悉的东西。我在这里错过了一些实用程序吗？
Thanks in advance.
提前致谢。

Process.GetCurrentProcess().StartTimeis your friend.
Process.GetCurrentProcess().StartTime是你的朋友。
..so to get elapsed time since start:
..so 获取自开始以来经过的时间：
DateTime.UtcNow - Process.GetCurrentProcess().StartTime.ToUniversalTime()
alternatively, if you need more definition, System.Diagnostics.Stopwatchmight be preferable. If so, start a stopwatch when your app starts:
或者，如果您需要更多定义，System.Diagnostics.Stopwatch可能更可取。如果是这样，请在您的应用程序启动时启动秒表：
Stopwatch sw = Stopwatch.StartNew();
then query the sw.Elapsedproperty during your execution run.
然后sw.Elapsed在执行运行期间查询该属性。
