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");
