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：

///         /// 获取客户端内网IP地址        /// 
        /// 
                  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 { } } ///  /// 获得客户端外网IP地址 /// 
 /// 
          
           IP地址
           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 { } }
