One of the quickest way is to using yahoo http request (some details can be found in see http://www.gummy-stuff.org/Yahoo-data.htm)
最快的方法之一是使用 yahoo http 请求（一些详细信息可以在http://www.gummy-stuff.org/Yahoo-data.htm 中找到）
Then using the following code to retrieve the result programmatically instead of manual download or using spreadsheet.
然后使用以下代码以编程方式检索结果，而不是手动下载或使用电子表格。
public static string Extract(string yahooHttpRequestString)
{
//if need to pass proxy using local configuration
System.Net.WebClient webClient = new WebClient();
webClient.Proxy = HttpWebRequest.GetSystemWebProxy();
webClient.Proxy.Credentials = CredentialCache.DefaultCredentials;
Stream strm = webClient.OpenRead(yahooHttpRequestString);
StreamReader sr = new StreamReader(strm);
string result = sr.ReadToEnd();
strm.Close();
return result;
}
then you can process the returned string further, or modify the above code to parse the string for each segment of the quote, into a more elaborated data structure.
然后你可以进一步处理返回的字符串，或者修改上面的代码以将引号的每个段的字符串解析为更详细的数据结构。
