[英]How to get total physical memory (ram) information in GB by WMI query?
我知道如何從win32_computersystem類獲取總物理內存。 但以字節或kb表示。 我想要此信息以MB或GB為單位。 在WMI(WQL)查詢中。 WMIC也可以。 提前致謝。
您必須手動轉換屬性的值。 也最好使用Win32_PhysicalMemory WMI類。
試試這個樣本
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();
}
}
}
您可以轉換Win32_ComputerSystem的 TotalPhysicalMemory
。 嘗試這個 :
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)
{
}
}
}
}
想要提及的是,在Windows Server 2012上遇到不一致的結果之前,我一直使用Win32_PhysicalMemory Capacity屬性。現在我同時使用兩個屬性(Win32_ComputerSystem:TotalPhysicalMemory和Win32_PhysicalMemory:Capacity),然后選擇兩者中較大的一個。
