软件开发过程中经常需要获取 CPU 序列号、MAC 序列号或者硬盘 ID 等系统信息，在给软件加序列号时这三个应该是最有用的，可以实现序列号和机器绑定，用于保护软件。下面看一下使用 C# 如何获取。
using System;using System.Management; // Computer Information public class Computer {public string CpuID; //1.cpu序列号public string MacAddress; //2.mac序列号public string DiskID; //3.硬盘idpublic string IpAddress; //4.ip地址public string LoginUserName; //5.登录用户名public string ComputerName; //6.计算机名public string SystemType;//7.系统类型public string TotalPhysicalMemory; //8.内存量 单位：M// 构造函数public Computer() {CpuID = GetCpuID();MacAddress = GetMacAddress();DiskID = GetDiskID(); IpAddress = GetIPAddress();LoginUserName = GetUserName();SystemType = GetSystemType(); TotalPhysicalMemory = GetTotalPhysicalMemory();ComputerName = GetComputerName();}// 1.获取CPU序列号string GetCpuID() {try {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 {}}// 2.获取网卡硬件地址string GetMacAddress() {try {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 {}}// 3.获取硬盘IDstring GetDiskID() {try {String HDid = "";ManagementClass mc = new ManagementClass("Win32_DiskDrive");ManagementObjectCollection moc = mc.GetInstances();foreach (ManagementObject mo in moc){HDid = (string)mo.Properties["Model"].Value;}moc = null;mc = null;return HDid;} catch {return "unknow";}finally {}}// 4.获取IP地址string GetIPAddress() {try {string st = "";ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");ManagementObjectCollection moc = mc.GetInstances();foreach (ManagementObject mo in moc) {if ((bool)mo["IPEnabled"] == true) {System.Array ar;ar = (System.Array)(mo.Properties["IpAddress"].Value); st = ar.GetValue(0).ToString(); break; } }moc = null; mc = null; return st; } catch {return "unknow";}finally {} }// 5.操作系统的登录用户名string GetUserName() {try {string un= "";st = Environment.UserName;return un; } catch {return "unknow"; } finally {} } // 6.获取计算机名string GetComputerName() {try {return System.Environment.MachineName;} catch {return "unknow"; } finally {} }// 7.PC类型 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 {} }// 8.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; } }
