如何将服务器URL IP地址转换为asp.net中的域名，c＃？

Hi
How to convert server URL IP Address to Domain name in asp.net,c#?

推荐答案

哪一个？可以从一个IP地址托管多个域。



您可以尝试：

Which one? A number of domains can be hosted from a single IP address.

You can try this:

IPAddress url = IPAddress.Parse("2.100.56.197");
IPHostEntry iphe = Dns.GetHostEntry(url);
Console.WriteLine(iphe.HostName);

但很有可能它在很多情况下不起作用。

But there is a good chance it won't work in a lot of cases.

// Get Ip Address from DomainName
static void GetIPAddress(string hostname)
{
    IPAddress[] ipAddr = Dns.GetHostAddresses(hostname);
    Console.WriteLine("GetHostAddresses({0}) :", hostname);

    foreach (IPAddress ip in ipAddr)
    {
        Console.WriteLine(ip);
    }
}

// Get HostName from IPAddress
static void GetDomainName(string ipaddress)
{
    IPHostEntry hostEntry = Dns.GetHostEntry(ipaddress);
    Console.WriteLine("DNS name : " + hostEntry.HostName);

    //Aliases if any
    String[] aliases = hostEntry.Aliases;
    for (int i = 0; i < aliases.Length; i++)
    {
        Console.WriteLine("Alias: " + aliases[i]);
    }
}
