interop::GetMonitorFromDisplayId function (microsoft.ui.interop.h)
Gets the HMONITOR that corresponds to the specified DisplayId, if the displayId argument is valid and the system has an HMONITOR that represents the display monitor.
Note
The microsoft.ui.interop.h header has a dependency on microsoft.ui.h, which is not shipped as part of the Windows App SDK. You can run the MIDL compiler (midl.exe) on Microsoft.UI.idl in order to generate microsoft.ui.h. Or just use the functions in the winrt/Microsoft.ui.interop.h header instead.
C#. For C# desktop application developers, the interop functions in this header are wrapped by the methods of the Microsoft.UI.Win32Interop class.
