asp.net use Google API to do translation _ practical skills

Description: Google provides a set of API can give us very convenient to achieve language translation functions, for us (Chinese), commonly used in Chinese and English translation. Good English can look at Google's documents:http://code.google.com/apis/ajaxlanguage/documentation/reference.html

Need to use to Json.NET in http://www.codeplex.com/Json download.

What is serialization? You can look at the article in front of me. http://www.sosuo8.com/article/show.asp?id=2470

In fact, Google has provided a very convenient translation function in JS, but in some cases we need to operate under. Net. What's the situation? Collect Chinese articles and translate them into English, or write a C/s software. Below I will mainly paste out the code, concrete can see miracle write article.
It needs to use:
encodeURIComponent
The value is passed.
Main code:

Copy Code code as follows:

<summary>
REPLACES special translated characters for line-wrapping, etc.
</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>
Use WebRequest to get Google translated content
</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>
Translation
</summary>
<param name= "str" > What needs to be translated </param>
<param name= "Strreuest" > Original </param>
<param name= "strresult" > Translation </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 "error occurred";
}
}
Else
{
return str;
}

}
catch (Exception ex)
{
Return ex. message;
}
}

deserialization:

Copy Code code as follows:

Using System;

<summary>
Deserialization
</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>
Content of the translation
</summary>
public class Translatedtext
{
private string _translatedtext;
public string Translatedtext
{
Get
{
return _translatedtext;
}
Set
{
_translatedtext = value;
}
}
}
}
