求助：使用C#获取物理内存量
需要获取系统的总物理内存量及剩余内存量。参考了sno888在2008-9-8回复“准确获取内存”的内容，编写的代码如下：
ManagementClass memo = new ManagementClass("Win32_OperatingSystem");
ManagementObjectCollection memoVol = memo.GetInstances();
double capacity = 0;
foreach (ManagementObject mo in memoVol)
{
capacity += ((Math.Round(Int64.Parse(mo.Properties["FreePhysicalMemory"].Value.ToString()) / 1024 / 1024 / 1024.0, 1)));
}
运行上述代码，得到的capacity值为0，是何原因？请教各位高手^^

MEMORYSTATUS ms = new MEMORYSTATUS();
NativeMethods.GlobalMemoryStatus(out ms);
MessageBox.Show((ms.dwTotalPhys/1024/1024).ToString());
[System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential)]
public struct MEMORYSTATUS
{
/// DWORD->unsigned int
public uint dwLength;
/// DWORD->unsigned int
public uint dwMemoryLoad;
/// SIZE_T->ULONG_PTR->unsigned int
public uint dwTotalPhys;

public uint dwTotalPageFile;
/// SIZE_T->ULONG_PTR->unsigned int
public uint dwAvailPageFile;
/// SIZE_T->ULONG_PTR->unsigned int
public uint dwTotalVirtual;
/// SIZE_T->ULONG_PTR->unsigned int
public uint dwAvailVirtual;
}
public partial class NativeMethods
{
/// Return Type: void
///lpBuffer: LPMEMORYSTATUS->_MEMORYSTATUS*
[System.Runtime.InteropServices.DllImportAttribute("kernel32.dll", EntryPoint = "GlobalMemoryStatus")]
public static extern void GlobalMemoryStatus([System.Runtime.InteropServices.OutAttribute()] out MEMORYSTATUS lpBuffer);
}
补充：.NET技术 , C#
