從谷歌和譯典通能上自動下載英語單詞mp3的好方法

最近在學英語，很多單詞不怎么會讀．每次得去iciba.com和dreye.com上查，很是麻煩！

后來一想，能不能寫個程序自動下載？測試一番，最終搞定！

下載的都是真人語音mp3，效果很棒！谷歌愛詞霸是女聲發音，譯典通是男聲發音，各有千秋．

核心的代碼：

bool DownMp3FromDrEye(string word, string localPath)
??????? {
??????????? HttpWebRequest webRequest = WebRequest.Create("http://www.dreye.com.cn/ews/dict.php") as HttpWebRequest;
??????????? webRequest.Method =?"POST";
??????????? webRequest.ContentType =?"application/x-www-form-urlencoded";

??????????? string postString =?"w="?+ word;
??????????? postString = System.Web.HttpUtility.HtmlEncode(postString);
??????????? byte[] postData = Encoding.ASCII.GetBytes(postString);
??????????? webRequest.ContentLength = postData.Length;

??????????? Stream reqStream = webRequest.GetRequestStream();
??????????? reqStream.Write(postData, 0, postData.Length);
??????????? reqStream.Close();

??????????? Stream respStream = webRequest.GetResponse().GetResponseStream();
??????????? StreamReader reader =?new StreamReader(respStream, true);
??????????? string html = reader.ReadToEnd();
??????????? respStream.Close();
??????????? //Debug.Write(html);

??????????? string prefix =?"http{add}";
??????????? int i = html.IndexOf(prefix);

??????????? Debug.WriteLine("Word:"?+ word +?", URL; "?+ mp3Url);

??????????? HttpWebRequest webRequest1 = WebRequest.Create(new Uri(wordWebUrl)) as HttpWebRequest;

??????? void DownFile(string fileUrl, string localPath, bool replace)
