Detailed explanation of C# using Youdao IP address query interface method example

This article describes the C# using Youdao IP address query interface method. Share it for your reference. The specific implementation method is as follows:

#region Read interface IP address/// &lt;summary&gt;
/// Read the interface IP address/// &lt;/summary&gt;
public static string GetstringIpAddress(string strIP)//strIP is IP{
 string sURL = "/smartresult-xml/?type=ip&amp;q="+strIP+"";
 //youdao's URL string stringIpAddress = "";
 using (XmlReader read = (sURL))
 //Get the xml format file content returned by youdao {
  while (())
  {
   switch ()
   {
    case ://Get the text content in the xml format file     if (("{0}", ).ToString().Trim() != strIP)
     //One of the xml format file contents returned by youdao is IP.     //The other is the IP address. If it is not an IP, then it is the IP address     {
      stringIpAddress=("{0}", ).ToString().Trim();//Assignment     }
     break;
    //other
   }
  }
 }
 return stringIpAddress;
}

The returned xml data format:

&lt;?xml version="1.0" encoding="gbk" ?&gt; 
&lt;smartresult&gt;
&lt;product type="ip"&gt;
&lt;ip&gt;60.223.233.226&lt;/ip&gt; 
&lt;location&gt;Shuozhou City, Shanxi Province Netcom&lt;/location&gt; 
&lt;/product&gt;
&lt;/smartresult&gt;
