C#如何读取硬件信息

Question

用C#如何读取硬件信息，获得各个硬件的基本信息。如显卡的品牌、硬盘品牌等。

Answer 1

WMI 获取硬件信息
ManagementClass driveClass = new ManagementClass("Win32_DiskDrive");

Answer 4

参考8楼的就可以了。我下面的代码可以获取显卡信息。 ManagementClass mc = new ManagementClass("Win32_VideoController");            ManagementObjectCollection moc = mc.GetInstances();            StringBuilder content = new StringBuilder("Video controller infomation:\r\n");
            content.Append("----------\r\n");            content.Append(moc.Count.ToString() + " Video controller in your PC\r\n\r\n");            int index = 0;            foreach (ManagementObject mo in moc)
            {
                content.Append("Video controller " + index.ToString() + " :\r\n");                foreach (PropertyData data in mo.Properties)
                {
                    content.Append("\t" + data.Name + "\t:\t" + ((data.Value != null) ? (data.Value.ToString() + "\r\n") : "") + "\r\n");
                }
            }

Answer 5

  RegistryKey Rkey = Registry.LocalMachine;
            richTextBox1.Text = "";
            Rkey = Rkey.OpenSubKey("HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0");
            richTextBox1.Text += "处理器信息:\r\n" + Rkey.GetValue("ProcessorNameString").ToString().Replace("  ", "");
            richTextBox1.Text += "\r\n计算机名:\r\n" + System.Windows.Forms.SystemInformation.ComputerName.ToString();
            richTextBox1.Text += "\r\n用户系统中磁盘分区:\r\n";
            for (int i = 0; i < Environment.GetLogicalDrives().Length; i++)
            {
                richTextBox1.Text += Environment.GetLogicalDrives()[i] + " ";
            }
            Rkey = Registry.LocalMachine;
            //GetOsVersion()//取得操作系统版本 
            //GetMemInfo();//取得内存信息 
            //GetDriverInfo();//取得驱动器信息 
            //GetCpuInfo();//
            MEMORYSTATUS1 vBuffer = new MEMORYSTATUS1();//实例化结构
            GlobalMemoryStatus(ref   vBuffer);//给此结构赋值
            string useinfo = Convert.ToString(vBuffer.dwAvailPhys);//获得已用内存量
            string allinfo = Convert.ToString(vBuffer.dwTotalPhys);//获得内存总量
            //MessageBox.Show(useinfo + ":" + allinfo);
            int infoAll, infoUsed;
            infoAll = int.Parse(allinfo) / 1024/1024;
            infoUsed = int.Parse(useinfo) / 1024/1024;
            richTextBox1.Text += "\r\n已用内存容量:"+infoUsed.ToString() +"MB\r\n"+"系统内存总量:"+ infoAll.ToString()+"MB";这一段

Answer 6

WMI
这东西很好玩的ManagementClass driveClass = new ManagementClass("SELECT * FROM Win32_Printer");不过就是太慢了

Answer 7

WMI API还有.net架构提供的对象等等。
