C# 如何从Win32_CDROMDrive WMI类获取接口类型？

我已经实现了的目标，但在WMI类中不存在该属性（InterfaceType）

如何获取光盘驱动器的接口类型？是否存在另一种获得它的方法

提前感谢。

您可以从

DeviceID

或

PNPDeviceID

属性中提取接口类型

试试这个样品

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 = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", "localhost"), null);
                Scope.Connect();
                ObjectQuery Query = new ObjectQuery("SELECT * FROM Win32_CDROMDrive");
                ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);

                foreach (ManagementObject WmiObject in Searcher.Get())
                {
                    String InterfaceType =  ((String)WmiObject["DeviceID"]).Substring(0, ((String)WmiObject["DeviceID"]).IndexOf(@"\"));
                    Console.WriteLine("{0,-35} {1,-40}", "InterfaceType", InterfaceType);
                    Console.WriteLine("{0,-35} {1,-40}","Drive",WmiObject["Drive"]);
                    Console.WriteLine("{0,-35} {1,-40}","Name",WmiObject["Name"]);

                }
            }
            catch (Exception e)
            {
                Console.WriteLine(String.Format("Exception {0} Trace {1}",e.Message,e.StackTrace));
            }
            Console.WriteLine("Press Enter to exit");
            Console.Read();
        }
    }
}

如果您在CD-ROM界面上运行Win32_DiskDrive，会发生什么情况？@RobertHarvey，它只显示计算机上安装的实际硬盘驱动器。嗯，我认为您无法从该类中获得它。如果您检查PNPDeviceID的前3个字符，您可以判断它是否是USB，但仅此而已。看见
