我知道如何从 win32_computersystem 类获取总物理内存。但这是以字节或 kb 为单位的。我想要此信息以 MB 或 GB 为单位。在 wmi (wql) 查询中。 wmic 也可以工作。预先感谢。
您可以转换
Win32_ComputerSystem的
TotalPhysicalMemory
。试试这个:
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)
{
}
}
}
}
您必须手动转换属性的值。最好还是使用 Win32_PhysicalMemory WMI 类。
尝试这个示例
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();
}
}
}
想要提一下,我使用了 Win32_PhysicalMemory 容量属性,直到在 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。

Get-WmiObject 在 PowerShell 3.0 及更高版本中已弃用。 (来源:https://ss64.com/ps/get-wmiobject.html)
Get-WmiObject 正在替换为 Get-CimInstance,它在很多方面都好得多!
如果您仍然想这样做,请考虑使用以下 -
$MemoryUncleaned = (Get-CimInstance Win32_PhysicalMemory | Measure-Object -Property capacity -Sum).sum /1gb
$Memory = $MemoryUncleaned.ToString() + "GB"
$Memory
64GB
