如何解决主机名在Metro / WinRT的IP地址？ [英] How to resolve a hostname to an IP address in Metro/WinRT?

问题描述

我在一个移植WP7应用到Windows 8 Metro和我所遇到的基于主机名或DNS名称发现一个IP地址（多）转换障碍之一的过程。以下是我以前使用WP7中的一个例子：

  DnsEndPoint dnsEnd =新DnsEndPoint（www.google.com ，80，AddressFamily.InterNetwork）; 
 DeviceNetworkInformation.ResolveHostNameAsync（dnsEnd，IPLookupCallbackMethod，这一点）; 
  

我在网上搜索了一个解决方案，并浏览了地铁API，但我没有发现任何东西然而。有没有其他人遇到这个问题，地铁/ WinRT中，发现一个解决办法？

解决方案

 使用Windows.Networking;使用Windows.Networking.Sockets 
; 
 
主机名SERVERHOST =新的主机名（www.google.com）; 
 StreamSocket ClientSocket的=新Windows.Networking.Sockets.StreamSocket（）; 
 
 //尝试连接到远程主机的
等待clientSocket.ConnectAsync（SERVERHOST，HTTP）; 
 
 //现在尝试clientSocket.Information财产
 //例如clientSocket.Information.RemoteAddress 
 //获取IP地址
  

一旦ClientSocket的试图连接时，clientSocket.Information属性将凭借丰富的网络信息，包括远程主机的信息，包括IP地址进行水合。所以我希望没有错误，我刚才输入这行内。希望这可以帮助！也可以尝试此链接到MSDN 。

I'm in the process of porting a WP7 app to Windows 8 Metro and one of the (many) conversion obstacles I've encountered is discovering an IP address based on a hostname or DNS name. The following is an example of what I was previously using in WP7:

DnsEndPoint dnsEnd = new DnsEndPoint("www.google.com", 80, AddressFamily.InterNetwork);
DeviceNetworkInformation.ResolveHostNameAsync(dnsEnd, IPLookupCallbackMethod, this);

I've searched online for a solution and browsed the Metro API, but I haven't found anything yet. Has anyone else encountered this problem with Metro/WinRT and found a solution?

解决方案

using Windows.Networking;
using Windows.Networking.Sockets;

HostName serverHost = new HostName("www.google.com");
StreamSocket clientSocket = new Windows.Networking.Sockets.StreamSocket();

// Try to connect to the remote host
await clientSocket.ConnectAsync(serverHost, "http");

// Now try the clientSocket.Information property
// e.g. clientSocket.Information.RemoteAddress
// to get the ip address

Once the clientSocket has attempted a connection, the clientSocket.Information property will be hydrated with a wealth of networking information including the remote host information including ip address. I just typed this inline so I hope there are no errors. Hope this helps! Also try this link to msdn.
