WP7芒果 - 如何获取IP地址对于一个给定的主机名 [英] WP7 Mango - How to get an IP address for a given hostname

问题描述

我需要得到一个IP地址从一个DnsEndPoint一个给定的主机名，并将其转换为一个IPEndPoint。我将如何去这样做呢？ WP7缺乏Dns.GetHostEntry功能，所以有没有办法做到这一点，而无需创建一个Socket，发送数据到主机，然后从主机接收ping和阅读RemoteEndPoint属性来获取主机的IP地址？

I need to get an IP address for a given hostname from a DnsEndPoint, and convert it to an IPEndPoint. How would I go about doing this? WP7 lacks a Dns.GetHostEntry function, so is there any way to do this without creating a Socket, sending data to the host, then receiving a ping from the host and reading the RemoteEndPoint property to get the IP address of the host?

推荐答案

尝试使用 DeviceNetworkInformation.ResolveHostNameAsync 在微软.Phone.Net.NetworkInformation 命名空间，就像这样：

Try using DeviceNetworkInformation.ResolveHostNameAsync in the Microsoft.Phone.Net.NetworkInformation namespace, like this:

public void DnsLookup(string hostname)
{
    var endpoint = new DnsEndPoint(hostname, 0);
    DeviceNetworkInformation.ResolveHostNameAsync(endpoint, OnNameResolved, null);  
}

private void OnNameResolved(NameResolutionResult result)
{
    IPEndPoint[] endpoints = result.IPEndPoints;
    // Do something with your endpoints
}
