How to get total physical memory (ram) information in GB by WMI query?
提问by user2287201
I know how to get total physical memory from win32_computersystem class. but that comes in bytes or kb. I want this information in MB or GB. in wmi (wql) query. wmic also work. thanks in advance.

You must convert the value of the property manually. Also is better use Win32_PhysicalMemoryWMI class.
您必须手动转换属性的值。也最好使用Win32_PhysicalMemoryWMI 类。
Try this sample
试试这个样本
using System;
using System.Collections.Generic;
using System.Management;
using System.Text;
namespace GetWMI_Info
{
class Program
{
static void Main(string[] args)
{
try
{
ManagementScope Scope;
Scope = new ManagementScope(String.Format("\\{0}\root\CIMV2", "."), null);
Scope.Connect();
ObjectQuery Query = new ObjectQuery("SELECT Capacity FROM Win32_PhysicalMemory");
ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);
UInt64 Capacity = 0;
foreach (ManagementObject WmiObject in Searcher.Get())
{
Capacity+= (UInt64) WmiObject["Capacity"];
}
Console.WriteLine(String.Format("Physical Memory {0} gb", Capacity / (1024 * 1024 * 1024)));
Console.WriteLine(String.Format("Physical Memory {0} mb", Capacity / (1024 * 1024)));
}
catch (Exception e)
{
Console.WriteLine(String.Format("Exception {0} Trace {1}", e.Message, e.StackTrace));
}
Console.WriteLine("Press Enter to exit");
Console.Read();
}
}
}

you can convert TotalPhysicalMemoryof Win32_ComputerSystem. Try this :
你可以转换TotalPhysicalMemory的的Win32_ComputerSystem。尝试这个 ：
using System;
using System.Management;
namespace WMISample
{
public class MyWMIQuery
{
public static void Main()
{
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\CIMV2",
"SELECT TotalPhysicalMemory FROM Win32_ComputerSystem");
foreach (ManagementObject queryObj in searcher.Get())
{
double dblMemory;
if(double.TryParse(Convert.ToString(queryObj["TotalPhysicalMemory"]),out dblMemory))
{
Console.WriteLine("TotalPhysicalMemory is: {0} MB", Convert.ToInt32(dblMemory/(1024*1024)));
Console.WriteLine("TotalPhysicalMemory is: {0} GB", Convert.ToInt32(dblMemory /(1024*1024*1024)));
}
}
}
catch (ManagementException e)
{
}
}
}
}

Wanted to make mention that I used the Win32_PhysicalMemory Capacity property until I met inconsistent results on Windows Server 2012. Now I use both properties (Win32_ComputerSystem:TotalPhysicalMemory and Win32_PhysicalMemory:Capacity) and choose the larger of the two.
想提一下，我使用了 Win32_PhysicalMemory 容量属性，直到我在 Windows Server 2012 上遇到不一致的结果。现在我使用这两个属性（Win32_ComputerSystem:TotalPhysicalMemory 和 Win32_PhysicalMemory:Capacity）并选择两者中较大的一个。
