本文告诉大家如何在 C# .NET 获取本机 IP 地址
有两个获取方法,第一个方法是通过 DNS 获取
var host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var ip in host.AddressList)
{
// 下面的判断过滤 IP v4 地址
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
Console.WriteLine(ip.ToString());
}
}
第二个方法可以过滤指定是 WIFI 的地址还是有限网的地址
foreach (NetworkInterface item in NetworkInterface.GetAllNetworkInterfaces())
{
if
((
item.NetworkInterfaceType == NetworkInterfaceType.Ethernet // 有线网络
|| item.NetworkInterfaceType == NetworkInterfaceType.Wireless80211 // 无线 wifi 网络
)
&& item.OperationalStatus == OperationalStatus.Up)
{
foreach (UnicastIPAddressInformation ip in item.GetIPProperties().UnicastAddresses)
{
if (ip.Address.AddressFamily == AddressFamily.InterNetwork)
{
Console.WriteLine(ip.Address.ToString());
}
}
}
}
过滤方法通过 NetworkInterfaceType 判断
