判断客户端相关信息

 

【本机IP地址】第一种方法：IPHostEntry hostentry = Dns.Resolve(Dns.GetHostName());IPAddress address=hostentry.AddressList[0];第二种方法：Dns.GetHostAddresses(Dns.GetHostName())[0].ToString();【判断当前用户是否连网】PingReply reply = new Ping().Send(address);        if (reply.Status == IPStatus.Success)           MessageBox.Show("Ping successfully.");        else           MessageBox.Show("Ping failure.");【获取当前客户端硬盘盘符】string[] mydrivers = Directory.GetLogicalDrives();【判断客户端移动硬盘、硬盘】SelectQuery select = new SelectQuery("select * from win32_logicaldisk");            ManagementObjectSearcher mos = new ManagementObjectSearcher(select);            foreach (ManagementObject disk in mos.Get())            {                string msg = disk["Name"].ToString();                DriveInfo info = new DriveInfo(msg);                switch (info.DriveType.ToString())                {                    case "Unknown":                        label1.Text += msg + "这是未知设备__";                        break;                    case "NoRootDirectory":                        label1.Text += msg + "这是未分区__";                        break;                    case "Removable":                        label1.Text += msg + "这是可以动磁盘__";                        break;                    case "Fixed":                        label1.Text += msg + "这是硬盘__";                        break;                    case "Network":                        label1.Text += msg + "这是网络驱动器__";                        break;                    case "CDRom":                        label1.Text += msg + "这是光驱__";                        break;                }            }【获取当前显示的长宽】宽：Screen.PrimaryScreen.WorkingArea.Width 长：Screen.PrimaryScreen.WorkingArea.Height【获取客户端进程信息】System.Diagnostics.Process[] processes = System.Diagnostics.Process.GetProcesses();【关闭进程信息】 foreach (System.Diagnostics.Process p in processes)            {                if (p.ProcessName == "IntelliTrace")                {                    p.Kill();               }           }【判断客户端是否安装声卡】        [DllImport("winmm.dll", EntryPoint = "waveOutGetNumDevs")]        public static extern int waveOutGetNumDevs();        private void button1_Click(object sender, EventArgs e)        {            if (waveOutGetNumDevs() != 0)            {                MessageBox.Show("已经安装声卡");            }            else {                MessageBox.Show("未安装声卡");            }        }【获取计算机名称和当前登录用户】计算机名称： Dns.GetHostName();当前登录用户：Environment.GetEnvironmentVariable("UserName");
