我從msdn站點（代碼如下）發現了一些code，看起來它會返回給定服務器的所有DNS別名。我已經在cosole應用程序中實現了代碼，應該允許我輸入服務器的主機名，並且它應該返回所有的dns別名。我輸入已知有別名的域中的服務器的主機名（我可以ping主機和別名，它們都解析爲相同的IP），但是此代碼未找到別名。 Obvously我的DNS別名和/或代碼缺乏瞭解......請教育我......查詢DNS別名
static void Main(string[] args)
{
Console.Write("Host? (Enter for local): ");
string strHost = Console.ReadLine();
if (strHost.Trim().Length == 0)
{
strHost = System.Net.Dns.GetHostName();
}
try
{
//System.Net.IPAddress hostIPAddress = System.Net.IPAddress.Parse(strHost);
System.Net.IPHostEntry hostInfo = System.Net.Dns.GetHostByName(strHost);//.GetHostByAddress(hostIPAddress);
// Get the IP address list that resolves to the host names contained in
// the Alias property.
System.Net.IPAddress[] address = hostInfo.AddressList;
// Get the alias names of the addresses in the IP address list.
String[] alias = hostInfo.Aliases;
Console.WriteLine("Host name : " + hostInfo.HostName);
Console.WriteLine("\nAliases :");
for (int index = 0; index < alias.Length; index++)
{
Console.WriteLine(alias[index]);
}
Console.WriteLine("\nIP address list : ");
for (int index = 0; index < address.Length; index++)
{
Console.WriteLine(address[index]);
}
