如何从 UWP 应用获取诊断统计信息

Question

我们需要将我们拥有的应用程序升级到通用 Windows 应用程序 (UWP) 框架。该应用程序的主要目的是收集诊断统计信息并通过 rest 调用将它们发送回我们的服务器。

但是我找不到任何 api 可用于获取统计信息

之前我们是

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 };
    }

返回已用和可用内存的总字节数。我们还收集了网络和 cpu 统计数据。 None 其中与新框架兼容。我应该为这个功能寻找什么命名空间？或者我需要使用 Pinvoke () 之类的东西吗？

Answer 1

您可以使用 MemoryManager 获取设备的内存

https://msdn.microsoft.com/en-us/library/windows.system.memorymanager.aspx

还可以获取设备信息

https://msdn.microsoft.com/en-us/library/windows/apps/windows.system.profile.aspx

更新：这是获取当前设备更多详细信息的示例 https://www.suchan.cz/2015/08/uwp-quick-tip-getting-device-os-and-app-info/

最后我发现调用本机函数是最好的解决方案。 Link: really good pinvoke site
