C# 获取IPV4地址，网关，子网掩码，网卡信息的方法
///这里是获取本机IPV4，网卡地址，网关，子网掩码
ManagementClassmc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection nics = mc.GetInstances();
foreach (ManagementObjectnic in nics)
{
if (Convert.ToBoolean(nic["ipEnabled"]) == true)
{
Console.WriteLine( (nic["IPAddress"] asString[])[0]);
Console.WriteLine( ["IPSubnet"] asString[])[0]）;
Console.WriteLine( (nic["DefaultIPGateway"] asString[])[0]);
}
}
////这个获取网卡一些信息
NetworkInterface[] adapters =NetworkInterface.GetAllNetworkInterfaces();//获取本地计算机上网络接口的对象
Console.WriteLine("适配器个数：" + adapters.Length);
Console.WriteLine();
foreach (NetworkInterfaceadapter in adapters)
{
Console.WriteLine("描述：" +adapter.Description);
Console.WriteLine("标识符：" + adapter.Id);
Console.WriteLine("名称：" + adapter.Name);
Console.WriteLine("类型：" +adapter.NetworkInterfaceType);
Console.WriteLine("速度：" + adapter.Speed *0.001 * 0.001 + "M");
Console.WriteLine("操作状态：" + adapter.OperationalStatus);
Console.WriteLine("MAC 地址：" +adapter.GetPhysicalAddress());
// 格式化显示MAC地址
PhysicalAddresspa = adapter.GetPhysicalAddress();//获取适配器的媒体访问（MAC）地址
byte[] bytes =pa.GetAddressBytes();//返回当前实例的地址
StringBuilder sb = newStringBuilder();
for (int i = 0; i
{
sb.Append(bytes[i].ToString("X2"));//以十六进制格式化
if (i != bytes.Length- 1)
{
sb.Append("-");
}
}
Console.WriteLine("MAC 地址：" + sb);
Console.WriteLine();
