The following small series for everyone to bring an article WinForm C # get the MAC address, IP address, subnet mask, the default gateway instance. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting. 1. Add an assembly 2. Introduce namespaces Using System.Management; 3. Methods ManagementClass mc = new ManagementC
