I want create Resources monitor as UWP application. 我想将资源监视器创建为UWP应用程序。 I read a lot about performanceCounter class from System.Diagnostics but... this class is not contain to UWP. 我从System.Diagnostics中阅读了很多关于performanceCounter类的信息，但是...该类不包含在UWP中。 Then i read about some native classes but my skill is too low to implement this yet ;/. 然后，我了解了一些本机类，但是我的技能太低，无法实现； //。

Then i found ProcessCpuUsage class Windows.SystemDiagnostics; 然后我找到了ProcessCpuUsage类Windows.SystemDiagnostics; and i tried implements this class but i cant find info about constructors and i dont know how implements it? 我试过实现此类，但是我找不到有关构造函数的信息，我也不知道如何实现它？ What info can i get from this class ? 我可以从这堂课中学到什么信息？

In my app i need string with cpu/ram usage, and info about free disk space, and i want to show it as widget. 在我的应用程序中，我需要使用cpu / ram用法的字符串以及有关可用磁盘空间的信息，并且我想将其显示为小部件。 Please Help. 请帮忙。

ProcessCpuUsage class has no constructor, it provides access to data about the CPU usage of a process. ProcessCpuUsage类没有构造函数，它提供对有关进程CPU使用率的数据的访问。 And this class only has a GetReport method, which gets the ProcessCpuUsageReport for the process. 并且此类仅具有GetReport方法，该方法获取流程的ProcessCpuUsageReport 。 With ProcessCpuUsageReport class, we can get KernelTime and UserTime consumed by the process. 使用ProcessCpuUsageReport类，我们可以获取进程消耗的KernelTime和UserTime 。

To get a ProcessCpuUsage object, we need use ProcessDiagnosticInfo.CpuUsage property. 要获取ProcessCpuUsage对象，我们需要使用ProcessDiagnosticInfo.CpuUsage属性。 This is one of the properties in ProcessDiagnosticInfo class. 这是ProcessDiagnosticInfo类的属性之一。 This class provides diagnostic information about a process, such as CPU usage, disk usage, memory usage and so on. 此类提供有关进程的诊断信息，例如CPU使用率，磁盘使用率，内存使用率等。 And ProcessDiagnosticInfo class has two static methods: GetForCurrentProcess and GetForProcesses that help us to get the ProcessDiagnosticInfo . ProcessDiagnosticInfo类具有两个静态方法： GetForCurrentProcess和GetForProcesses ，它们可以帮助我们获取ProcessDiagnosticInfo 。

However, please note that these two methods can only get the ProcessDiagnosticInfo related to your own app . 但是，请注意，这两种方法只能获取与您自己的应用程序相关的ProcessDiagnosticInfo 。 GetForProcesses method can return a list of ProcessDiagnosticInfo objects for all running processes. GetForProcesses方法可以返回所有正在运行的进程的ProcessDiagnosticInfo对象的列表。 But here the "all running processes" means all running processes in the same App Container. 但是这里的“所有正在运行的进程”是指同一App容器中的所有正在运行的进程。 For example, for a UWP with out-of-process background tasks , GetForProcesses method may return several ProcessDiagnosticInfo s including running background tasks. 例如，对于具有进程外后台任务的UWP， GetForProcesses方法可能返回几个ProcessDiagnosticInfo包括正在运行的后台任务。 But for a simple UWP app, it may always return one ProcessDiagnosticInfo . 但是对于一个简单的UWP应用，它可能总是返回一个ProcessDiagnosticInfo 。 This method can't return diagnostic informations for all running processes in the computer/device as UWP apps are running in app containers and isolated from each other. 由于UWP应用程序正在应用程序容器中运行并且彼此隔离，因此该方法无法返回计算机/设备中所有正在运行的进程的诊断信息。

So if you are going to create a resources monitor application, UWP may be not a good choice. 因此，如果要创建资源监视器应用程序，则UWP可能不是一个好选择。 Classic desktop apps might be better for your scenario. 经典桌面应用程序可能更适合您的方案。
