本文实例讲述了C#获取机器码的方法。分享给大家供大家参考，具体如下：

using System.Runtime.InteropServices; using System.Management; using System; public class HardwareInfo { //取机器名 public string GetHostName() { return System.Net.Dns.GetHostName(); } //取CPU编号 public String GetCpuID() { try { ManagementClass mc = new ManagementClass("Win32_Processor"); ManagementObjectCollection moc = mc.GetInstances(); String strCpuID = null ; foreach( ManagementObject mo in moc ) { strCpuID = mo.Properties["ProcessorId"].Value.ToString(); break; } return strCpuID; } catch { return ""; } }//end method //取第一块硬盘编号 public String GetHardDiskID() { try { ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia"); String strHardDiskID = null ; foreach(ManagementObject mo in searcher.Get()) { strHardDiskID = mo["SerialNumber"].ToString().Trim(); break; } return strHardDiskID ; } catch { return ""; } }//end public enum NCBCONST { NCBNAMSZ =16, /* absolute length of a net name */ MAX_LANA =254, /* lana's in range 0 to MAX_LANA inclusive */ NCBENUM =0x37, /* NCB ENUMERATE LANA NUMBERS */ NRC_GOODRET =0x00, /* good return */ NCBRESET =0x32, /* NCB RESET */ NCBASTAT =0x33, /* NCB ADAPTER STATUS */ NUM_NAMEBUF =30, /* Number of NAME's BUFFER */ } [StructLayout(LayoutKind.Sequential)] public struct ADAPTER_STATUS { [MarshalAs(UnmanagedType.ByValArray, SizeConst=6)] public byte[] adapter_address; public byte rev_major; public byte reserved0; public byte adapter_type; public byte rev_minor; public ushort duration; public ushort frmr_recv; public ushort frmr_xmit; public ushort iframe_recv_err; public ushort xmit_aborts; public uint xmit_success; public uint recv_success; public ushort iframe_xmit_err; public ushort recv_buff_unavail; public ushort t1_timeouts; public ushort ti_timeouts; public uint reserved1; public ushort free_ncbs; public ushort max_cfg_ncbs; public ushort max_ncbs; public ushort xmit_buf_unavail; public ushort max_dgram_size; public ushort pending_sess; public ushort max_cfg_sess; public ushort max_sess; public ushort max_sess_pkt_size; public ushort name_count; } [StructLayout(LayoutKind.Sequential)] public struct NAME_BUFFER { [MarshalAs(UnmanagedType.ByValArray, SizeConst=(int)NCBCONST.NCBNAMSZ)] public byte[] name; public byte name_num; public byte name_flags; } [StructLayout(LayoutKind.Sequential)] public struct NCB { public byte ncb_command; public byte ncb_retcode; public byte ncb_lsn; public byte ncb_num; public IntPtr ncb_buffer; public ushort ncb_length; [MarshalAs(UnmanagedType.ByValArray, SizeConst=(int)NCBCONST.NCBNAMSZ)] public byte[] ncb_callname; [MarshalAs(UnmanagedType.ByValArray, SizeConst=(int)NCBCONST.NCBNAMSZ)] public byte[] ncb_name; public byte ncb_rto; public byte ncb_sto; public IntPtr ncb_post; public byte ncb_lana_num; public byte ncb_cmd_cplt; [MarshalAs(UnmanagedType.ByValArray, SizeConst=10)] public byte[] ncb_reserve; public IntPtr ncb_event; } [StructLayout(LayoutKind.Sequential)] public struct LANA_ENUM { public byte length; [MarshalAs(UnmanagedType.ByValArray, SizeConst=(int)NCBCONST.MAX_LANA)] public byte[] lana; } [StructLayout(LayoutKind.Auto)] public struct ASTAT { public ADAPTER_STATUS adapt; [MarshalAs(UnmanagedType.ByValArray, SizeConst=(int)NCBCONST.NUM_NAMEBUF)] public NAME_BUFFER[] NameBuff; } public class Win32API { [DllImport("NETAPI32.DLL")] public static extern char Netbios(ref NCB ncb); } //取网卡mac public string GetMacAddress() { string addr=""; try { int cb; ASTAT adapter; NCB Ncb=new NCB(); char uRetCode; LANA_ENUM lenum; Ncb.ncb_command = (byte)NCBCONST.NCBENUM; cb = Marshal.SizeOf(typeof(LANA_ENUM)); Ncb.ncb_buffer = Marshal.AllocHGlobal(cb); Ncb.ncb_length = (ushort)cb; uRetCode = Win32API.Netbios(ref Ncb); lenum = (LANA_ENUM)Marshal.PtrToStructure(Ncb.ncb_buffer, typeof(LANA_ENUM)); Marshal.FreeHGlobal(Ncb.ncb_buffer); if(uRetCode != (short)NCBCONST.NRC_GOODRET) return ""; for(int i=0; i < lenum.length ;i++) { Ncb.ncb_command = (byte)NCBCONST.NCBRESET; Ncb.ncb_lana_num = lenum.lana[i]; uRetCode = Win32API.Netbios(ref Ncb); if(uRetCode != (short)NCBCONST.NRC_GOODRET) return ""; Ncb.ncb_command = (byte)NCBCONST.NCBASTAT; Ncb.ncb_lana_num = lenum.lana[i]; Ncb.ncb_callname[0]=(byte)'*'; cb = Marshal.SizeOf(typeof(ADAPTER_STATUS)) + Marshal.SizeOf(typeof(NAME_BUFFER))*(int)NCBCONST.NUM_NAMEBUF; Ncb.ncb_buffer = Marshal.AllocHGlobal(cb); Ncb.ncb_length = (ushort)cb; uRetCode = Win32API.Netbios(ref Ncb); adapter.adapt = (ADAPTER_STATUS)Marshal.PtrToStructure(Ncb.ncb_buffer, typeof(ADAPTER_STATUS)); Marshal.FreeHGlobal(Ncb.ncb_buffer); if (uRetCode == (short)NCBCONST.NRC_GOODRET) { if(i>0) addr += ":"; addr = string.Format("{0,2:X}{1,2:X}{2,2:X}{3,2:X}{4,2:X}{5,2:X}", adapter.adapt.adapter_address[0], adapter.adapt.adapter_address[1], adapter.adapt.adapter_address[2], adapter.adapt.adapter_address[3], adapter.adapt.adapter_address[4], adapter.adapt.adapter_address[5]); } } } catch { } return addr.Replace(' ', '0'); } }
