範例
下列程式代碼範例會以標準壓縮格式顯示目前主機的 None 位址值。
// This method displays the value of the current host's None address in
// standard compressed format. The None address is used by the host to disable
// listening to client activities on all the interfaces.
void displayIPv6NoneAddress()
{
try
{
// Get the None address.
IPAddress^ none = IPAddress::IPv6None;
// Transform the None address to a string using the overloaded
// ToString() method. Note that the resulting string is in the compact
// form: "::".
String^ ipv6None = none->ToString();
Console::WriteLine( "The IPv6 None address is: {0}", ipv6None );
}
catch ( Exception^ e )
{
Console::WriteLine( "->Item[displayIPv6NoneAddress] Exception: {0}", e );
}
}

Console.WriteLine("The IPv6 None address is: " + ipv6None);
}
catch (Exception e)

Console.WriteLine("[displayIPv6NoneAddress] Exception: " + e.ToString());
}
}

備註
方法 Socket.Bind 會 IPv6None 使用欄位來 Socket 表示 不得接聽客戶端活動。 欄位 IPv6None 相當於 0:0:0:0:0:0:0:0:0,以冒號十六進位表示法表示,或等於 ::0。
