說明：google提供了一組API可以給我們很方便的實現(xiàn)語言翻譯功能，對于我們(中國人)而言，常用的是中文與英文的互譯。大家英文好的可以看看GOOGLE的文檔：http://code.google.com/apis/ajaxlanguage/documentation/reference.html#LangNameArray

這篇文章原創(chuàng)在：http://blog.moozi.net/archives/2008/10/16/the-realization-of-web-service-of-full-text-translations-based-on-google-ajax-language-api.aspx

需要使用到JSON.NET在http://www.codeplex.com/Json下載。

什么是序列化？可以看看我前面的文章。http://www.sosuo8.com/article/show.asp?id=2470

其實google已經(jīng)提供了在JS下很方便的翻譯功能，但有些情況下我們卻需要在.net下操作。什么情況？采集中文文章并翻譯成英文入庫，或者是寫一個C/S的軟件。下面我將主要貼出代碼，具體的可以看木子寫的文章。
其需要用：
encodeURIComponent
傳值。
主要代碼：

復制代碼代碼如下:

/// <summary> 
/// 替換翻譯后的特殊字符，用于換行等 
/// </summary> 
/// <param name="str"></param> 
/// <returns></returns> 
private string TransToHtml(string str) 
{ 
string temp; 
temp = str.Replace("003c", "<"); 
temp = temp.Replace("003e",">"); 
return temp; 
} 

/// <summary> 
/// 使用WebRequest獲取Google翻譯后的內(nèi)容 
/// </summary> 
/// <param name="str"></param> 
/// <param name="strRequestLan"></param> 
/// <param name="strResultLan"></param> 
/// <returns></returns> 
private string GetGoogleTransJSONString(string str, string strRequestLan, string strResultLan) 
{ 
try 
{ 
WebRequest request = HttpWebRequest.Create("http://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=" + str + "&langpair=" + strRequestLan + "%7C" + strResultLan); 
request.Credentials = CredentialCache.DefaultCredentials; 
HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
Stream stream = response.GetResponseStream(); 
StreamReader reader = new StreamReader(stream); 
string responseFromServer = reader.ReadToEnd(); 
reader.Close(); 
stream.Close(); 
response.Close(); 
return responseFromServer; 
} 
catch (Exception ex) 
{ 
return ex.Message; 
} 
} 


/// <summary> 
/// 翻譯 
/// </summary> 
/// <param name="str">需要翻譯的內(nèi)容</param> 
/// <param name="strReuest">原文</param> 
/// <param name="strResult">譯文</param> 
/// <returns></returns> 
public string Translate(string str, string strReuestLan, string strResultLan) 
{ 
try 
{ 
if (!string.IsNullOrEmpty(str)) 
{ 
TranslateString transtr = (TranslateString)Newtonsoft.Json.JavaScriptConvert.DeserializeObject(GetGoogleTransJSONString(str, strReuestLan, strResultLan),typeof(TranslateString)); 
if (transtr.responseStatus == 200) 
{ 
return transtr.responseData.translatedText; 
} 
else 
{ 
return "有錯誤發(fā)生"; 
} 
} 
else 
{ 
return str; 
} 

} 
catch (Exception ex) 
{ 
return ex.Message; 
} 
} 

反序列化：

復制代碼代碼如下:

using System; 

/// <summary> 
///反序列化 
/// </summary> 
/// {"responseData": {"translatedText":"ahuinan"}, "responseDetails": null, "responseStatus": 200} 
[Serializable] 
public class TranslateString 
{ 
private TranslatedText _responseData; 
private string _responseDetails; 
private int _responseStauts; 

public TranslatedText responseData 
{ 
get 
{ 
return _responseData; 
} 
set 
{ 
_responseData = value; 
} 
} 

public string responseDetails 
{ 
get 
{ 
return _responseDetails; 
} 
set 
{ 
_responseDetails = value; 
} 
} 

public int responseStatus 
{ 
get 
{ 
return _responseStauts; 
} 
set 
{ 
_responseStauts = value; 
} 
} 

/// <summary> 
/// 譯文內(nèi)容 
/// </summary> 
public class TranslatedText 
{ 
private string _translatedText; 
public string translatedText 
{ 
get 
{ 
return _translatedText; 
} 
set 
{ 
_translatedText = value; 
} 
} 
} 
}
