#region Read http://www.yodao.com interface IP address///<summary>///Read http://www.yodao.com interface IP address///</summary> public The static string getstringipaddress (String StrIP)//strip is an IP {string surl = "http://www.youdao.com/smartresult-xml/ Search.s?type=ip&q= "+strip+"; Youdao URL string stringipaddress = ""; using (XmlReader read = Xmlreader.create (sURL))//Get Youdao returned XML format file content {while read. Read ()) {switch (read. NodeType) {Case xmlnodetype.text://takes the text content of an XML format file if (string. Format (' {0} ', read. Value). ToString ().
