C#中获取本机IP地址 子网掩码 网关地址

首先添加对程序集System.Management的引用

usingSystem;usingSystem.Management;namespaceConsoleApplication1{classProgram{staticvoidMain(string[]args){ManagementClassmc=newManagementClass("Win32_NetworkAdapterConfiguration");ManagementObjectCollectionnics=mc.GetInstances();foreach(ManagementObjectnicinnics){if(Convert.ToBoolean(nic["ipEnabled"])==true){Console.WriteLine((nic["IPAddress"]asString[])[0]);Console.WriteLine((nic["IPSubnet"]asString[])[0]);Console.WriteLine((nic["DefaultIPGateway"]asString[])[0]);}}}}}
