C# 获取系统盘符

1、使用.net管理对象（引入System.Management）

        public static List<string> getDisk()
        {
            WqlObjectQuery wmiquery = new WqlObjectQuery("select * from Win32_LogiCalDisk");
            ManagementObjectSearcher wmifind = new ManagementObjectSearcher(wmiquery);
            ManagementObjectCollection queryCollection = wmifind.Get();
            List<string> ls = new List<string>();
            foreach (var disk in queryCollection)
            {
                ls.Add(disk["DeviceID"].ToString());
            }
            return ls;
        }

2、使用驱动信息（引入System.IO）

        public static List<string> getDisk()
        {
            var drivers = DriveInfo.GetDrives();
            List<string> ls = new List<string>();
            foreach (var driver in drivers)
            {
