C#使用System.Management类库获取本机信息

首先需要使用依赖库

using System.Management;

获取CPU代码

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 
            { 
            }

获取网卡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 
            { 
            } 

        }

获取到的网卡地址是6位16进制数，如44:33:66:FF:CC:CF

获报IP地址

string GetIPAddress() 
        { 
            try 
            { 
                //获取IP地址 
                string st = ""; 
                ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); 
                ManagementObjectCollection moc = mc.GetInstances(); 
                foreach (ManagementObject mo in moc) 
                { 
                    if ((bool)mo["IPEnabled"] == true) 
                    { 
                        //st=mo["IpAddress"].ToString(); 
                        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 
            { 
            } 
        }

获取硬盘ID

 string GetDiskID() 
        { 
            try 
            { 
                //获取硬盘ID 
                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 
            { 
            }

获取操作系统的登录用户名

/// <summary> 
        /// 操作系统的登录用户名 
        /// </summary> 
        /// <returns></returns> 
        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PC类型

   /// <summary> 
        /// PC类型 
        /// </summary> 
        /// <returns></returns> 
        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 
            { 
            } 

        }

获取物理内存信息

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

有些可以直接在系统环境变量中获取，如下：

获取获取电脑名称

        /// <summary> 
        ///  获取电脑名称
        /// </summary> 
        /// <returns></returns> 
        string GetComputerName() 
        { 
            try 
            { 
                return System.Environment.GetEnvironmentVariable("ComputerName"); 
            } 
            catch 
            { 
                return "unknow"; 
            } 
            finally 
            { 
            } 
        }
