获取计算机的网卡及打印机信息

1.获取网卡地址：

 1  private string GetMacAddress()
 2         {
 3             string code = null;
 4             SelectQuery query = new SelectQuery("select * from Win32_ComputerSystemProduct");
 5             using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
 6             {
 7                 foreach (var item in searcher.Get())
 8                 {
 9                     using (item) code = item["UUID"].ToString();
10                 }
11             }
12             return code;
13         }

2.获取本机系统打印机：

 1         [DllImport("winspool.drv")]
 2         public static extern bool SetDefaultPrinter(String Name); //调用win api将指定名称的打印机设置为默认打印机
 3 
 4         private static PrintDocument pd = new PrintDocument();
 5         //获取本机默认打印机名称
 6         public static String DefaultPrinter()
 7         {
 8             return pd.PrinterSettings.PrinterName;
 9         }
10         public static List<String> GetLocalPrinters()
11         {
12             List<String> fPrinters = new List<String>();
13             fPrinters.Add(DefaultPrinter()); //默认打印机始终出现在列表的第一项
14             foreach (String fPrinterName in PrinterSettings.InstalledPrinters)
15             {
16                 if (!fPrinters.Contains(fPrinterName))
17                 {
18                     fPrinters.Add(fPrinterName);
19                 }
20             }
21             return fPrinters;
22         }

显示在下拉列表中

1   List<String> list = LocalPrinter.GetLocalPrinters(); //获得系统中的打印机列表
2             foreach (String s in list)
3             {
4                 printerComboBox.Items.Add(s); //将打印机名称添加到下拉框中
5             }
6             printerComboBox.SelectedIndex = 0;
