如何從UWP應用程序獲取診斷統計信息

我們需要將我們的應用程序升級到通用Windows應用程序（UWP）框架。該應用程序的主要目的是收集診斷統計信息並通過其餘呼叫將它們發送回我們的服務器。如何從UWP應用程序獲取診斷統計信息

但是我沒有發現任何的API可用於獲取統計

此前我們

PerformanceCounter _memoryCounter = new PerformanceCounter(); 

public SystemProperty GetPhysicalMemory() 
    { 
     string s = _QueryComputerSystem("totalphysicalmemory"); 
     double totalphysicalmemory = Convert.ToDouble(s); 
     double d = _GetCounterValue(_memoryCounter, "Memory", "Available Bytes", null); 
     return new SystemProperty { PropertyName = "Physical Memory", Total = totalphysicalmemory, Used = totalphysicalmemory - d }; 
    }

這回總使用和內存可用字節

。我們還收集了網絡和CPU統計信息。其中沒有一個與新框架兼容。我應該在哪些名稱空間中查看此功能？或者我需要使用Pinvoke（link）之類的東西？

最後我發現調用本地函數是最好的解決方案。鏈接：really good pinvoke site
