我们在利用C#开发桌面程序（Winform）程序的时候，

经常需要获取一些跟系统相关的信息，

以下这些代码获取能有些用处。

c#中如何获取本机用户名、MAC地址、IP地址、硬盘ID、CPU序列号、系统名称、物理内存。

首先需要引入命名空间：

using System.Management;

/// 操作系统的登录用户名：

string GetUserName(){    try    {        string st = "";        ManagementClass mc = new ManagementClass("Win32_ComputerSystem");        ManagementObjectCollection moc = mc.GetInstances();        foreach (ManagementObject mo in moc)        {			 st = mo["UserName"].ToString();        }        moc = null;        mc = null;        return st;    }    catch    {        return "unknow";    }    finally	{     } }

//获取MAC地址：

string GetMacAddress(){    try    {        //获取网卡硬件地址        string mac = "";        ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");        ManagementObjectCollection moc = mc.GetInstances();        foreach (ManagementObject mo in moc)        {            if ((bool)mo["IPEnabled"] == true)            {                mac = mo["MacAddress"].ToString();                break;            }        }        moc = null;        mc = null;        return mac;    }    catch    {        return "unknow";    }    finally    {     }}

//获取IP地址：

        /// <summary>        /// 获取客户端内网IP地址        /// </summary>        /// <returns></returns>        private static string getClientLocalIPAddress()        {            string localIP=null;            try            {                IPHostEntry ipHost = System.Net.Dns.GetHostEntry(Dns.GetHostName());// Dns.Resolve(Dns.GetHostName()); ;                IPAddress ipaddress = ipHost.AddressList[0];                localIP = ipaddress.ToString();                return "内网IP地址："+localIP;            }            catch            {                return "内网IP地址：unknown";            }            finally            {              }        }         /// <summary>        /// 获得客户端外网IP地址        /// </summary>        /// <returns>IP地址</returns>        public static string getClientInternetIPAddress()        {            string internetAddress = "";            try            {                using (WebClient webClient = new WebClient())                {                    internetAddress = webClient.DownloadString("http://www.coridc.com/ip");//从外部网页获得IP地址                    //判断IP是否合法                    if (!System.Text.RegularExpressions.Regex.IsMatch(internetAddress, "[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}"))                    {                        internetAddress = webClient.DownloadString("http://fw.qq.com/ipaddress");//从腾讯提供的API中获得IP地址                    }                }                return "外网IP地址：" + internetAddress;            }            catch            {                return "外网IP地址：unknown";            }            finally            {             }        }

//获取硬盘ID：

string GetDiskID(){    try    {        String HDid = "";        ManagementClass mc = new ManagementClass("Win32_DiskDrive");        ManagementObjectCollection moc = mc.GetInstances();        foreach (ManagementObject mo in moc)        {            //HDid = (string)mo.Properties["Model"].ToString();            HDid = (String)mo.Properties["Model"].Value.ToString();        }        moc = null;        mc = null;        return HDid;    }    catch    {        return "unknow";    }    finally    {     }}

//获取CPUid：

string GetCpuID(){    try    {        //获取CPU序列号代码        string cpuInfo = "";//cpu序列号        ManagementClass mc = new ManagementClass("Win32_Processor");        ManagementObjectCollection moc = mc.GetInstances();        foreach (ManagementObject mo in moc)        {            cpuInfo = mo.Properties["ProcessorId"].Value.ToString();        }        moc = null;        mc = null;        return cpuInfo;    }    catch    {        return "unknow";    }    finally    {     }}

//系统名称：

string GetSystemType(){    try    {        string st = "";        ManagementClass mc = new ManagementClass("Win32_ComputerSystem");        ManagementObjectCollection moc = mc.GetInstances();        foreach (ManagementObject mo in moc)        {            st = mo["SystemType"].ToString();        }        moc = null;        mc = null;        return st;    }    catch    {        return "unknow";    }    finally    {     }}

//获取物理内存：

string GetTotalPhysicalMemory(){    try    {        string st = "";        ManagementClass mc = new ManagementClass("Win32_ComputerSystem");        ManagementObjectCollection moc = mc.GetInstances();        foreach (ManagementObject mo in moc)        {            st = mo["TotalPhysicalMemory"].ToString();        }        moc = null;        mc = null;        return st;    }    catch    {        return "unknow";    }    finally    {     }}
