C#实现获取计算机信息

 一、基本信息

1、本机名

 public static string getLocalhostName(){
    return Environment.GetEnvironmentVariable("COMPUTERNAME");
 }

2、获取本机MAC地址

public static string getLocalhostMac() {
    string mac = null;
    ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration");
    ManagementObjectCollection queryCollection = query.Get();
    foreach (ManagementObject mo in queryCollection) {
        if (mo["IPEnabled"].ToString() == "True")
        mac = mo["MacAddress"].ToString();
    }
    return (mac);
}

3、获取计算机名

public static string getComputerName() {
    return Environment.MachineName;
}

4、显示器分辨率

public static string getResolution() {
    return SystemInformation.PrimaryMonitorMaximizedWindowSize.Width + " x " + SystemInformation.PrimaryMonitorMaximizedWindowSize.Height;
}

5、主显示器分辨率

public static string getMainResolution() {
    return SystemInformation.PrimaryMonitorSize.Width + " x " + SystemInformation.PrimaryMonitorSize.Height;
}

6、系统路径

[DllImport("kernel32")]
public static extern void GetSystemDirectory(StringBuilder SysDir, int count);
 
public static string getSystemPath() {
    const int nChars = 128;
    StringBuilder Buff = new StringBuilder(nChars);
    GetSystemDirectory(Buff, nChars);
    return Buff.ToString();
}

二、操作系统信息

1、操作系统类型

public static string getSystemType() {
    string st = "";
    ManagementClass mc = new ManagementClass("Win32_ComputerSystem");
    ManagementObjectCollection moc = mc.GetInstances();
    foreach (ManagementObject mo in moc) {
        st = mo["SystemType"].ToString();
    }
    return st;
}

2、获得操作系统位数

public static string getOSBit() {
    if (Environment.Is64BitOperatingSystem) {
        return "64bit."
    } else {
        return  "32bit.";
    }
}

3、获得操作系统版本

public static string getOSVersion()  {
    return Environment.OSVersion.VersionString;
}

三、处理器信息

1 、处理器个数

public static string getProcessorCount()  {
    return Environment.ProcessorCount.ToString();
}

四、CPU信息

1、CPU的个数
