我创建了一个方法，使用thesaurus.com查找单词的同义词，我正在寻找评论和反馈。无论在速度，安全性，可靠性方面（无论依靠第三方网站进行查询的“可靠性”）等，我都能以何种方式改进它。

/// This method relies heavily on thesaurus.com for synonym lookups. It is not completely reliable, but is deemed reliable enough in instances where you dont have your own thesaurus

public static string[] GetSynonyms(string word)
{
string url = string.Format("http://thesaurus.com/search?q={0}", word);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
List<string> synonyms = new List<string>();
StringBuilder data = new StringBuilder();
string line;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
//we know that the synonyms is in the upper-part of the html stream so we do not want to read the entire stream.
while((line = reader.ReadLine()) != null) {
var index = line.IndexOf("<span class=\"text\">");
if(index > 0)
{
index = index + "<span class=\"text\">".Length;
synonyms.Add(line.Substring(index).Replace("</span>", ""));
}
//break when we come to the Antonyms section of the page
if (line.Contains("container-info antonyms"))
{
break;
}
}
}
return synonyms.ToArray<string>();
}
else
{
return null;
}
}
编辑：例如，现在需要大约3.5秒来查找单词“old”的同义词。
