【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__";

                }
            }




【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)
            {

        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 {
