Question

我正在尝试获取PC上安装的RAM类型。我能够找到一个代码示例，但它并没有真正起作用，它告诉我DDR2总是未知。对于DDR3，它也总是返回0.对于SDRAM来说这个字很好

编辑：不应该认为它可以在XP上运行。

    public string RAM_Type()
    {

        int type=0;
        var searcher = new ManagementObjectSearcher("Select * from Win32_PhysicalMemory");
        foreach (ManagementObject obj in searcher.Get())
        {
           type = Int32.Parse(obj.GetPropertyValue("MemoryType").ToString());

        }

        switch (type)
        {
            case 20:
                return "DDR";
                break;
            case 21:
                return "DDR-2";
                break;
            case 17:
                return "SDRAM";
                break;
            default:
                if (type == 0 || type > 22)
                    return "DDR-3";
                else
                    return "Unknown";
        }

    }

.NET没有提供获取我所知道的内存类型的方法。

.Net中的现有方法仅返回等效值，但必须按照本指南手动完成对字符串的转换：Win32_PhysicalMemory class

我为此目的制作了一个专门课程，我将代码翻译成各自的名称

using System;
using System.Management;

namespace Hector
{
    public class RamInfo
    {
        public static string RamType
        {
            get
            {
                int type = 0;

                ConnectionOptions connection = new ConnectionOptions();
                connection.Impersonation = ImpersonationLevel.Impersonate;
                ManagementScope scope = new ManagementScope("\\\\.\\root\\CIMV2", connection);
                scope.Connect();
                ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_PhysicalMemory");
                ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
                foreach (ManagementObject queryObj in searcher.Get())
                {
                    type = Convert.ToInt32(queryObj["MemoryType"]);
                }

                return TypeString(type);
            }
        }

        private static string TypeString(int type)
        {
            string outValue = string.Empty;

            switch (type)
            {
                case 0x0: outValue = "Unknown"; break;
                case 0x1: outValue = "Other"; break;
                case 0x2: outValue = "DRAM"; break;
                case 0x3: outValue = "Synchronous DRAM"; break;
                case 0x4: outValue = "Cache DRAM"; break;
                case 0x5: outValue = "EDO"; break;
                case 0x6: outValue = "EDRAM"; break;
                case 0x7: outValue = "VRAM"; break;
                case 0x8: outValue = "SRAM"; break;
                case 0x9: outValue = "RAM"; break;
                case 0xa: outValue = "ROM"; break;
                case 0xb: outValue = "Flash"; break;
                case 0xc: outValue = "EEPROM"; break;
                case 0xd: outValue = "FEPROM"; break;
                case 0xe: outValue = "EPROM"; break;
                case 0xf: outValue = "CDRAM"; break;
                case 0x10: outValue = "3DRAM"; break;
                case 0x11: outValue = "SDRAM"; break;
                case 0x12: outValue = "SGRAM"; break;
                case 0x13: outValue = "RDRAM"; break;
                case 0x14: outValue = "DDR"; break;
                case 0x15: outValue = "DDR2"; break;
                case 0x16: outValue = "DDR2 FB-DIMM"; break;
                case 0x17: outValue = "Undefined 23"; break;
                case 0x18: outValue = "DDR3"; break;
                case 0x19: outValue = "FBD2"; break;
                case 0x1a: outValue = "DDR4"; break;
                default: outValue = "Undefined"; break;
            }

            return outValue;
        }
    }
}

private void Form1_Load(object sender, EventArgs e)
{
    label1.Text = Hector.RamInfo.RamType;
}

Answer 2

有一些已知的issues具有此值和一些操作系统。它似乎也取决于存储器本身，并非所有存储器都具有在其EEPROM中编码的信息。

一种替代方法是直接查询SMBIOS。

此处还有program（尽管在c ++中），您可以帮助诊断问题，并了解如何获取您要检索的信息。
