Windows Phone 7调用必应翻译服务

xuke123

　　这讲是介绍如何在Windows Phone上调用必应翻译服务。想必大家也知道必应为我们提供了很多服务，诸如搜索、地图、翻译等。前面已经介绍了如何在Windows Phone上调用必应的地图服务，今天调用必应的翻译服务，在它的服务中包含36种以上语言，包括简体中文、繁体中文等。下面是一个快照。有兴趣的朋友赶快行动吧！


　　
　　效果图如下

　　起始界面
　　

　　没有选择语言时弹出提示框
　　

　　没有输入数据时弹出提示框
　　

　　翻译完成后界面
　　
　　好啦！开始吧.
　　Step 1：创建语言类Language.cs
　　每种语言都有两个属性，Name，Code。如上俩图中文的Name是chinese simplified，Code是zh-CHS.


public class Language
{
    public string Code { get; set; }
    public string Name { get; set; }
}　　
　　　Step 2：用户接口
　　我们定义了一些控件，并绑定Language的Name属性，来显示数据。




源语言:








目标语言:











　　
　　在MainPage.cs文件中定义三个List，来保存数据。
　　private List codes;
        　　　　　　private List names;
        　　　　　　private List languages;
　　
　　Step 3：使用Bing SOAP 服务
　　添加服务引用，地址为：http://api.microsofttranslator.com/V2/Soap.svc，LanguageServiceClient是一个Proxy，提供了一些调用服务的方法。下面我们定义一个对象
　　private BTS.LanguageServiceClient proxy;
　　要使用必应的翻译服务我们首先必须获取一个APP_ID，到http://cn.bing.com/developers/createapp.aspx网站，输入信息来获取。我注册的ID也可以使用，请看下图。

　　
　　接下来我们注册事件
　　proxy.GetLanguagesForTranslateCompleted += new EventHandler(proxy_GetLanguagesForTranslateCompleted);
      proxy.GetLanguageNamesCompleted += new EventHandler(proxy_GetLanguageNamesCompleted);
　　proxy.TranslateCompleted += new EventHandler(proxy_TranslateCompleted);
　　其中GetLanguagesForTranslateCompleted事件有一个GetLanguagesForTranslateCompletedEventArgs类型的参数。包含一些从服务中得到的数据，如Language的Code值。
　　GetLanguageNamesCompleted事件有一个GetLanguageNamesCompletedEventArgs类型的参数，包含Language的Name值。
　　TranslateCompleted事件将我们输入原语言的数据翻译为目标语言的数据。


  private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
proxy.GetLanguagesForTranslateCompleted += new EventHandler(proxy_GetLanguagesForTranslateCompleted);
proxy.GetLanguageNamesCompleted += new EventHandler(proxy_GetLanguageNamesCompleted);
proxy.TranslateCompleted += new EventHandler(proxy_TranslateCompleted);

proxy.GetLanguagesForTranslateAsync(APP_ID);
}

public void proxy_GetLanguagesForTranslateCompleted(object sender, BTS.GetLanguagesForTranslateCompletedEventArgs e)
{
codes = e.Result.ToList();

proxy.GetLanguageNamesAsync(APP_ID, "en", e.Result);
}

public void proxy_GetLanguageNamesCompleted(object sender, BTS.GetLanguageNamesCompletedEventArgs e)
{
names = e.Result.ToList();
loadLanguages();
}

public void proxy_TranslateCompleted(object sender, BTS.TranslateCompletedEventArgs e)
{
txtTarget.Text = e.Result;
}　　
　　现在给ListBox对象绑定数据


   private void loadLanguages()
{
for (int index = 0; index < codes.Count; index++)
{
languages.Add(new Language
{
Code = codes[index],
Name = names[index]
});
}

lbxFrom.ItemsSource = languages;
lbxTo.ItemsSource = languages;
}　　
　　定义Translate()方法来完成翻译


  private void Translate()
{
if (lbxFrom.SelectedItem == null || lbxTo.SelectedItem == null)
{
MessageBox.Show("请先选择语言","提示",MessageBoxButton.OK);

return;
}

if (this.txtOrign.Text.Trim().Length==0)
{
MessageBox.Show("请先输入要翻译的单词或语句","提示",MessageBoxButton.OK);

return;
}
else
{
Language from = lbxFrom.SelectedItem as Language;
Language to = lbxTo.SelectedItem as Language;

proxy.TranslateAsync(APP_ID, txtOrign.Text, from.Code, to.Code);
}
}
}
