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
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，
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：
/// <summary>
/// 获取客户端内网IP地址
/// </summary>
/// <returns></returns>
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";
}
/// <summary>
/// 获得客户端外网IP地址
/// </summary>
/// <returns>IP地址</returns>
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

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

ManagementClass mc = new ManagementClass("Win32_DiskDrive");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{

HDid = (String)mo.Properties["Model"].Value.ToString();
}
moc = null;
mc = null;
return HDid;
}
catch
{
return "unknow";
}
}
//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";
}
}
//系统名称：
string GetSystemType()
{
try

return st;
}

}
}
//获取系统名称
private static string GetSystemName()
{
string buffer = string.Empty;
ManagementObjectSearcher searcher;
searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT PartComponent FROM Win32_SystemOperatingSystem");
foreach (ManagementObject queryObj in searcher.Get())
{
buffer = queryObj["PartComponent"].ToString();
//会返回"\\ZHANGYUNYONG-PC\root\cimv2:Win32_OperatingSystem=@"
}
searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT Caption FROM Win32_OperatingSystem");
foreach (ManagementObject queryObj in searcher.Get())
{
buffer = queryObj["Caption"].ToString();
//会返回"Microsoft Windows 7 旗舰版 "
}
return buffer;
}
//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)
