Alternative Managed API:

GC.GetTotalMemory() can return the current memory in GC but no other details.

Notes:

Taken from openNetCF in OpenNETCF.Win32.Core

Tips & Tricks:

you can ignore the dwTotalPageFile and dwAvailPageFile as they are not supported

under CE

Sample Code:

    ''' <summary>
    ''' gets the memory status of the current ce platform
    ''' </summary>
    ''' <returns></returns>
    ''' <remarks></remarks>
    Public Shared Function GetMemory() As MEMORYSTATUS
    Dim ms As MEMORYSTATUS
    ms.dwLength = Marshal.SizeOf(ms)
    GlobalMemoryStatus(ms)
    Return ms
    End Function
