.net 获取声卡基本信息

通过 ManagementObjectSearcher 类查询 Win32_SoundDevice 信息,获取 PNPDeviceID 信息

        /// <summary>
        /// 声卡PNPDeviceID
        /// </summary>
        public string GetSoundPNPID()
        {
            string st = "";
            ManagementObjectSearcher mos = new ManagementObjectSearcher("Select * from Win32_SoundDevice");
            foreach (ManagementObject mo in mos.Get())
            {
                st = mo["PNPDeviceID"].ToString();
            }
            return st;
        }

运行结果:

获取声卡列表信息

通过ManagementObjectSearcher 类,初始化root\\CIMV2, 查询 Win32_SoundDevice 信息

遍历获取Name, Manufacturer , ProductName 值

        /// <summary>
        /// 获取声卡
        /// </summary>
        /// <returns></returns>
        public static string GetSoundAdapters()
        {

            ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_SoundDevice");
            StringBuilder stringBuilder = new StringBuilder();
            uint i = 1;
            foreach (ManagementObject wmi in searcher.Get())
            {
                var n = wmi.GetPropertyValue("Name")?.ToString().Replace("(TM)", "™").Replace("(tm)", "™").Replace("(R)", "®").Replace("(r)", "®").Replace("(C)", "©").Replace("(c)", "©");
                var m = wmi.GetPropertyValue("Manufacturer")?.ToString();
                var pn = wmi.GetPropertyValue("ProductName")?.ToString();
                stringBuilder.AppendLine($"序号{i}>>{n}，{m}");
                stringBuilder.AppendLine();
                i++;

            }
            return stringBuilder.ToString();
        }
