本文提供了一段C#代码，用于获取计算机的各种硬件信息，包括CPU序列号、MAC地址、硬盘ID、IP地址等，并介绍了如何使用System.Management命名空间来实现这些功能。

首先在资源管理~引用~中添加 System.Management 要不然会提示找不到System.Management命名空间

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id
public 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

public Computer()
{
CpuID = GetCpuID();
MacAddress = GetMacAddress();
DiskID = GetDiskID();
IpAddress = GetIPAddress();
LoginUserName = GetUserName();
SystemType = GetSystemType();
TotalPhysicalMemory = GetTotalPhysicalMemory();
ComputerName = GetComputerName();
}
//1.获取CPU序列号代码

string GetCpuID()
{
try
{
string cpuInfo = "";//cpu序列号
ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{

}
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)
{

break;
}
}

mc = null;
return mac;
}
catch
{
return "unknow";
}
finally
{
}

}

//3.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"].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)
{
//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
{
}

}

/// 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

ManagementClass mc = new ManagementClass("Win32_ComputerSystem");

{

}

return st;
}
catch
{
return "unknow";
}
finally
{
}
}

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)
{
