C#获取本机IP的6种方法
print?1、//GetHostName
private void GetIP()
{
string hostName = Dns.GetHostName();//本机名
//System.Net.IPAddress[] addressList = Dns.GetHostByName(hostName).AddressList;//会警告GetHostByName()已过期，我运行时且只返回了一个IPv4的地址
System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);//会返回所有地址，包括IPv4和IPv6
foreach (IPAddress ip in addressList)
{
listBox1.Items.Add(ip.ToString());
}
}
private void GetIP()
{
string hostName = Dns.GetHostName();//本机名
//System.Net.IPAddress[] addressList = Dns.GetHostByName(hostName).AddressList;//会警告GetHostByName()已过期，我运行时且只返回了一个IPv4的地址
System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);//会返回所有地址，包括IPv4和IPv6
foreach (IPAddress ip in addressList)
{
listBox1.Items.Add(ip.ToString());
}
}
1、//GetHostName
private void GetIP()
{
string hostName = Dns.GetHostName();//本机名
//System.Net.IPAddress[] addressList = Dns.GetHostByName(hostName).AddressList;//会警告GetHostByName()已过期，我运行时且只返回了一个IPv4的地址
System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);//会返回所有地址，包括IPv4和IPv6
foreach (IPAddress ip in addressList)
{
listBox1.Items.Add(ip.ToString());
}
}
2、使用IPHostEntry获取本机局域网地址
private void GetIP()
{
string hostName = Dns.GetHostName();//本机名
//System.Net.IPAddress[] addressList = Dns.GetHostByName(hostName).AddressList;//会警告GetHostByName()已过期，我运行时且只返回了一个IPv4的地址
System.Net.IPAddress[] addressList = Dns.GetHostAddresses(hostName);//会返回所有地址，包括IPv4和IPv6
foreach (IPAddress ip in addressList)
{
listBox1.Items.Add(ip.ToString());
}
}
2、使用IPHostEntry获取本机局域网地址
[csharp]
static string GetLocalIp()
拼魔方的技巧 {
string hostname = Dns.GetHostName();//得到本机名
//IPHostEntry localhost = Dns.GetHostByName(hostname);//方法已过期，只得到IPv4的地址
IPHostEntry localhost = Dns.GetHostEntry(hostname);
IPAddress localaddr = localhost.AddressList[0];
return localaddr.ToString();
}
拼魔方的技巧 {
string hostname = Dns.GetHostName();//得到本机名
//IPHostEntry localhost = Dns.GetHostByName(hostname);//方法已过期，只得到IPv4的地址
IPHostEntry localhost = Dns.GetHostEntry(hostname);
IPAddress localaddr = localhost.AddressList[0];
return localaddr.ToString();
}
static string GetLocalIp()
{
string hostname = Dns.GetHostName();//得到本机名
//IPHostEntry localhost = Dns.GetHostByName(hostname);//方法已过期，只得到IPv4的地址
IPHostEntry localhost = Dns.GetHostEntry(hostname);
{
string hostname = Dns.GetHostName();//得到本机名
//IPHostEntry localhost = Dns.GetHostByName(hostname);//方法已过期，只得到IPv4的地址
IPHostEntry localhost = Dns.GetHostEntry(hostname);
IPAddress localaddr = localhost.AddressList[0];
return localaddr.ToString();
}
3、获取本机网络ip地址
return localaddr.ToString();
