Hi Everyone,

I am working on a Windows 10 UWP app and I am trying to get to current memory usage by OS in an app like we see the memory in task manager. I am unable to find a solution.

Did anyone come across such a requirement or worked on it? Please help with a code snippet or any links with a solution.

Device memory

Thanks in advance!

    Welcome to Microsoft Q&A!

    How to get current memory usage by OS/device in a UWP Windows10 app programmatically?

    Currently, there is no API in UWP that could get the memory usage of the system. .NET APIs like PerformanceCounter are not support in UWP.

    You might need to take a look at GlobalMemoryStatusEx function which is a Win32 API that could be used in UWP. Based on the document, this API should be able to get the memory usage of the system that you required. Since it's a Win32 API, there is no code sample about how to use it in UWP app. You need to do it by yourself.

    Thank you.

    using Windows.System.Diagnostics;

    ulong availableSizeInBytes = SystemDiagnosticInfo.GetForCurrentSystem().MemoryUsage.GetReport().AvailableSizeInBytes;

    ulong totalPhysicalSizeInBytes = SystemDiagnosticInfo.GetForCurrentSystem().MemoryUsage.GetReport().TotalPhysicalSizeInBytes;

    decimal percentFree = ((decimal)availableSizeInBytes / (decimal)totalPhysicalSizeInBytes) * 100;

    decimal percentOccupied = 100 - percentFree;

    I can achieve it with the above code. Is it the correct way?
