C#获取电脑硬件信息

方法大多是从网上搜到的，由于出处太多,有一些方法又经过了修改，具体出处已无从考证，如有冒犯望谅解，此处仅供学习使用

首先引用System.Management

获取硬盘信息

1. 方法一

        /// <summary>
        /// 硬盘ID,大小
        /// </summary>
        /// <returns></returns>
        public Dictionary<string, string> GetDisk()  
        {
            Dictionary<string, string> dic = new Dictionary<string, string>();
            ManagementClass mc = new ManagementClass("Win32_DiskDrive");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                string HDid = (string)mo.Properties["Model"].Value;
                string bytes = mo["Size"].ToString();
                dic.Add(HDid, bytes);
            }
            moc = null;
            mc = null;
            return dic;   
        } 

1. 方法二

        /// <summary>
        /// 获取驱动盘符
        /// C,D,E,F
        /// </summary>
        /// <returns></returns>
        public List<string> GetRemovableDeviceID()
        {
            List<string> deviceIDs = new List<string>();
            ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT  *  From  Win32_LogicalDisk ");
            ManagementObjectCollection queryCollection = query.Get();
            foreach (ManagementObject mo in queryCollection)
            {
                switch (int.Parse(mo["DriveType"].ToString()))
                {
                    case (int)DriveType.Removable:   //可以移动磁盘       
                        {
                            //MessageBox.Show("可以移动磁盘");  
                            deviceIDs.Add(mo["DeviceID"].ToString());
                            break;
                        }
                    case (int)DriveType.Fixed:   //本地磁盘       
                        {
                            //MessageBox.Show("本地磁盘");  
                            deviceIDs.Add(mo["DeviceID"].ToString());
                            break;
                        }
                    case (int)DriveType.CDRom:   //CD   rom   drives       
                        {
                            //MessageBox.Show("CD   rom   drives ");  
                            break;
                        }
                    case (int)DriveType.Network:   //网络驱动     
                        {
                            //MessageBox.Show("网络驱动器 ");  
                            break;
                        }
                    case (int)DriveType.Ram:
                        {
                            //MessageBox.Show("驱动器是一个 RAM 磁盘 ");  
                            break;
                        }
                    case (int)DriveType.NoRootDirectory:
                        {
                            //MessageBox.Show("驱动器没有根目录 ");  
                            break;
                        }
                    default:   //defalut   to   folder       
                        {
                            //MessageBox.Show("驱动器类型未知 ");  
                            break;
                        }
                }

            }
            return deviceIDs;
        } 

1. 方法三

        /// <summary>  
        /// 物理内存  
        /// </summary>  
        /// <returns></returns>
