这是我用于 BindIPEndPointDelegate 的代码：
ServicePoint servicePoint,
IPEndPoint remoteEndPoint,
int retryCount)
{
if (lastIpEndpoint != null)
{
return lastIpEndpoint;
}
var candidates =
GetAddresses(remoteEndPoint.AddressFamily);
if (candidates == null || candidates.Count() == 0)
{
throw new NotImplementedException();
}
return
lastIpEndpoint = new IPEndPoint(candidates[rnd.Next(candidates.Count())], remoteEndPoint.Port);
};
static IPAddress[] GetAddresses(AddressFamily af)
{
System.Net.IPHostEntry _IPHostEntry = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName());
return (from i in _IPHostEntry.AddressList where i.AddressFamily == af select i).ToArray();
}
无论我做什么，我都会收到以下错误：
System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: The requested address is not valid in its context 173.194.39.68:80

代码有什么问题？
